11 conditions for using lime fertilizers
Why lime soils (part 3)
With liming of acidic soils, the nutrition of plants with nitrogen and ash elements - phosphorus, calcium, magnesium and molybdenum - improves. A number of conditions must be met.
1. Liming should be done regularly - once every five to six years. Under the influence of the processes occurring in the soil and the applied fertilizers, the reaction of the environment changes, after about five to six years it returns to its original level, therefore liming must be repeated periodically.
2. The positive effect of liming on most agricultural crops is fully manifested only when the ratio in the soil solution and the absorbing complex of the soil of calcium and magnesium is favorable for their growth and development. Plants can develop at different ratios between these cations, however, the best conditions for most plants are created when the ratio between Ca and Mg is 100: 40-80, i.e. 40-80 parts of Mg per 100 parts of Ca.
In strongly acidic sod-podzolic soils, poorly saturated with bases, especially of light texture, there is less magnesium absorbed than is required to create a favorable ratio between it and calcium. When lime fertilizers containing only CaCO3 are applied, the unfavorable ratio between these elements expands even more. Their too wide ratio in the absorbing complex and soil solution is the reason for the reduced efficiency and even the negative effect of lime on some plants.
The introduction of lime materials containing, along with calcium, a significant amount of magnesium, improves the ratio between these elements and therefore increases the yield of many crops more than the use of lime fertilizers that do not contain magnesium. Therefore, when applying calcium-only lime fertilizers, it is advisable to use them in conjunction with the corresponding magnesium fertilizers.
3. The effect of lime is significantly increased when it is used together with organic and mineral fertilizers, especially with manure, superphosphate, potassium, boric, copper, cobalt and bacterial fertilizers, which accelerate soil physicochemical reactions and more significantly increase soil fertility.
4. Before adding lime, you first need to determine the degree of need for a summer cottage in liming. It is known that the higher the acidity of the soil, the more the soil needs lime and the greater the increase in yield from liming. However, on slightly acidic and neutral soils, this method does not give a significant effect. Therefore, before adding lime, you need to make sure of the need (need) for liming.
The need for liming can be roughly determined by some external features of the soil. Strongly acidic soils have a whitish, gray tint, a pronounced podzolic horizon, reaching 10 centimeters or more in thickness. Such soils require liming in the first place.
The need for liming can be determined by the condition of some cultivated plants and the development of weeds. Poor growth and strong thinning of clover, beets, wheat and other crops that are most sensitive to high acidity (despite good agricultural technology, correct fertilization and other favorable conditions) indicate a high degree of liming need. The first two groups of plants strongly need liming, they do not tolerate excessive acidity, the third and fourth groups have an average need, and the fifth group of plants grows well on acidic soils and does not need liming. Some weeds and wild plants - sorrel, field coryza, pikulnik, creeping buttercup, whitebeard, pike, rump, wild rosemary, heather and others - grow well on acidic soils. Their abundant distribution on fields and roadsides indicates an increased acidity of the soil and the primary need for lime application.
The degree of soil acidity is an important, but not the only indicator characterizing the need for liming in soils. More precisely, the degree of plant need for liming can be established on the basis of a complete agrochemical analysis of the soil, determination of the exchange acidity (pH of the salt extract) and the degree of its saturation with bases (V), and its mechanical composition.
Depending on the exchangeable acidity with an average humus content (2-3%), soils are subdivided according to the degree of need for liming as follows: at pH 4.5 and below - the need is strong, from 4.6 to 5.0 - medium, from 5, 1 to 5.5 - weak and at a pH above 5.5 - the soil does not need liming.
Depending on the degree of saturation with bases, the soils are divided into the following groups: V = 50% and below - the need for liming is strong, 50-70% - medium, 70% and above - weak, more than 80% - the soil does not need liming.
The high content of aluminum, manganese, iron is also an important reason for the need for liming.
Liming can also serve as a means of obtaining hygienically healthy crop products, a means of reducing the harmful effects of heavy metals and radionuclides, the accumulation of which is associated not with acidity, but with pollution due to unreasonable human activities. In the presence of these signs, the need for liming increases greatly. With technogenic pollution of soils, the need for liming is high, although, according to the usual agrochemical indicators, they may not need lime at all.
5. Lime fertilizers should be used in optimal doses. With a strong need, full doses of lime are used, with an average one - you can do with half doses, with a weak one - in small doses or use a neutralizing lime additive.
The amount of lime required to reduce the increased acidity of the arable soil layer to a slightly acidic reaction (pH of the water extract 6.2-6.5, salt extract 5.6-5.8), favorable for most crops and beneficial microorganisms, is called the full or normal dose ... More precisely, the full dose of lime can be determined by the hydrolytic acidity. To calculate in this way the dose of lime (in grams of CaCO3 per 1 m²), multiply the value of hydrolytic acidity (Hg), expressed in meq. per 100 g of soil, by a factor of 150. Dose of CaCOz = NG150.
The dose of lime can be determined both by the pH value and the mechanical composition of the soil. At pH less than 4.5 on sandy loam and light loamy soils, the dose is 800-900 g / m2, and on medium and heavy loamy soils - 900-1200 g / m2, at pH 4.6-5.0 it is equal to 500-800, respectively , at pH 5.1-5.5 - 200 and 400 g / m².
There are complex methods for determining the doses of lime, but we will talk about them a little later.
6. Depending on the economic conditions, it is necessary to select the optimal methods of adding lime. A full dose of lime can be applied to the soil all at once or in several steps. When a full dose is applied in one step, a faster and more complete neutralization of the acidity of the entire arable layer of soil for a long time is achieved and higher yield increases for most agricultural crops are obtained. The introduction of a full dose of lime is especially important when cultivating crops that are sensitive to acidity on strongly acidic soils, as well as when deepening the arable layer of poorly cultivated sod-podzolic soils.
If it is not possible to apply a full dose of lime to the entire area of acidic soils at once, then liming is carried out in several stages. A half dose can be used instead of the full dose. In this case, twice the area is lime. However, the increase in yield from each square meter in this case will be 20-30% less, although the total increase from the entire area to which lime is applied will be higher in the first years than from the use of the full dose, but on an area that is half as much ... In the first years after application, the difference in the effectiveness of the full and half dose of lime is relatively small. However, in the second-third and subsequent years, the increase in yield from a half dose becomes almost two times less than from a full dose.
A full dose of lime has a positive effect on the yield on medium and heavy loamy soils for 5 years, and on soils with light texture - 2-4 years. The positive effect of a half dose is less lasting than a full dose, therefore, the second half of the dose is reintroduced in the same area after 1-2 years.
With the systematic use of mineral fertilizers, especially physiologically acidic fertilizers, the loss of calcium and magnesium increases significantly, and a more rapid acidification of previously calcified soils occurs. In this case, re-liming should be carried out after a shorter period.
The introduction of lime in small doses may be advisable only as an additional measure to increase yields in combination with other methods of using lime fertilizers, in particular, when acid-sensitive crops are sown on strongly acidic soil, and it is not possible or undesirable to apply the full dose. For example, if crop rotations with flax and potatoes contain crops such as clover, wheat, barley, peas, beets, corn, then it is advisable to combine the application of a half dose of lime for plowing with local application of small doses (50-100 g / m2) of it in rows when sowing a culture sensitive to an acid reaction. Spread application of a half dose of lime provides an optimal reaction of the medium for crops of the second-fourth group, and local application against this background of small doses of lime creates favorable conditions for the growth of plants that are more sensitive to an acid reaction.
A small amount of lime is also used in combination with mineral fertilizers to neutralize their potential acidity. In this case, lime is called a neutralizing additive to mineral fertilizers. At the same time, further acidification of the soil is prevented due to the physiological acidity of the fertilizers, which sharply increases the efficiency of all fertilizers.
To neutralize acidity, 1 kg of ammonium sulfate requires 1.3 kg of CaCO3, 1 kg of ammonium nitrate - 1 kg of CaCO3 and 1 kg of superphosphate - 0.1 kg of CaCO3. On average, it is believed that for each kg of mineral fertilizers, 1 kg of lime must be added to neutralize.
7. Lime is introduced taking into account the applied agricultural technology. Full doses of lime are added for digging in spring or summer after harvesting the main crop. In principle, lime can be applied in spring, summer or autumn. But it is better when the soil is being digged. It's spring or summer. The best time is spring, when mineral and organic fertilizers are applied. Then lime dissolves better and better reduces the acidity of the soil and the physiological acidity of fertilizers.
8. The application of lime fertilizers must be carried out taking into account the crop rotation and in combination with other fertilizers. In crop rotations with vegetables and fodder crops, all types of lime fertilizers are used; it is best to apply them in full dose at one time in the spring. In vegetable crop rotations, lime is applied directly under the cabbage or root crops.
When applying carbonic lime, it is necessary to combine liming with the use of manure and mineral fertilizers in crop rotation, and to apply boric fertilizers directly under root crops and potatoes, and on peaty soils - together with copper fertilizers.
It is especially important to apply increased doses of potassium fertilizers, since there is a certain antagonism of ions between calcium and potassium. With sufficient application of organic and mineral fertilizers, liming with full doses can also be carried out in crop rotations with potatoes.
In crop rotations with annual lupine or seradella for green fertilization, lime is applied when plowing these plants for fertilization.
On meadows and lawns, lime fertilizers are applied in a half dose superficially with harrowing in late autumn or early spring. With a radical improvement of meadows and lawns, a full dose of lime is used for plowing. Under the influence of lime, the number of acid-tolerant grasses and weeds decreases, and the number of legumes increases, the growth and development of grasses improves, as a result of which the yield and nutritional value of hay is greatly increased, as well as the design of the lawn is improved.
9. Lime is scattered on the soil first, creating the first and necessary contact of lime with the soil. Then mineral and organic fertilizers are scattered and then the fertilizers are mixed well with the soil by plowing or digging with the seam turnover.
10. Lime fertilizers must be dry and crumbly, in this case, their effectiveness will be the highest.
11. Lime should be applied in dry and calm weather.so that the fertilizer does not swell during sowing and does not stick together from dampness.
We wish you every success!

Fertilizing the lawn. Rules and terms of application.
Lawn fertilization provides optimal nutrition for lawn plants.
There are features and rules of application fertilizers on lawns, which should be guided by. Grass on lawn grows constantly, starting to grow back earlier than all cultivated plants (only alder, hazel, or hazelnuts are ahead of it, blooming in late March - early April, when all the snow has not yet melted, then coltsfoot, anemone, wolf and a small number species) - green meadows and lawns first of all confirm the arrival of spring.
With this in mind, the plants on the lawn must be constantly fed. fertilizers. So we will understand the question: Lawn fertilization.
On the lawn, they are always applied from the surface, without embedding. You need to distribute fertilizers evenly over the entire area.
It is necessary to apply only reasonable rates and doses of fertilizers: if the recommended rates are exceeded, damage (burnout) of grass stands is possible, spots or even completely, due to a re-concentration of the active substance (most often nitrogen).
With the introduction of lower doses, the grass stands on the lawns are thinned out, the leaves of the plants brighten, the intensity of the green color decreases, weeds and mosses settle in rarefied places.
Without fertilizers, the growth of grass stands stops by the middle of summer (at the end of June), they turn yellow, gray, losing their decorative effect, in addition, the life expectancy of the lawn is noticeably reduced. Fertilizers should be applied not on the growing grass stand, but immediately after the start of regrowth in the spring, when the lawn is just beginning to turn green, or after the next mowing.
To obtain a good fertilization effect, certain conditions are required, first of all, moderately humid weather. In too damp weather, nutrients may be washed out, and in dry times they are difficult for plants to access and, in addition, the loss of nutrients from fertilizers in gaseous form - into the air - increases. So in dry periods, fertilization must be accompanied by irrigation of grass stands.

Strawberry : when watering: 0.1-0.2% solution (1-2 kg / 1000 l of water). Foliar dressing: three times 5 kg / ha during the growth of the fruit.
It is strongly not recommended to mix calcium nitrate with fertilizers containing phosphates and sulfates, due to the precipitation of nutrients into the insoluble sediment. For this reason, calcium is usually not included in complex fertilizers. Calcinite must be applied separately from other complex fertilizers.
How to deoxidize the soil on the site
In the publication What is soil acidity and how it affects plants, we dealt with the theory (what is pH and acidity scale) and considered the effect of acidity of soil solutions on plants. Having learned to determine the degree of acidity in various ways, you can finally move on to the main question - how to deacidify the soil on the site.
In most of the territory of our country, due to climatic conditions, the soil itself is acidic. The use of fertilizers - organic, and especially mineral (ammonium nitrate, urea) - also increases acidity. Measures to improve the acid-base balance of the soil are called chemical reclamation... They consist in the use of lime fertilizers - substances containing hydroxides, oxides and carbonates of calcium (in most cases) and magnesium. Scientists believe that people began to engage in liming of soils in order to improve farmland as early as the 1st century BC. BC, and maybe even earlier, but there is no reliable evidence of this.
Liming is one of the oldest ways to improve soil fertility in different regions of the world.
The need to use lime fertilizers depends on the degree of soil acidity:
- strongly acidic (pH less than 4.5) very much in need of liming
- acidic (pH 4.6-5) - the need for liming is medium
- slightly acidic (pH 5.1-5.5) - the need for lime fertilizers is low
- soils close to neutral (pH 5.6-6) do not need deoxidation measures.
In agriculture, in addition to the acidity level (pH), when applying lime fertilizers, the saturation of the soil with bases and its granulometric composition are also taken into account. The need for liming also depends on the crops cultivated. So, beets and white cabbage, as well as other crops, whose optimal pH range lies in the range of 6-7.5 (see tables in the previous article), respond well to the application of lime fertilizers even on soils where the pH is close to neutral. This must be taken into account when crop rotation.
Different types of lime fertilizers have different characteristics - particle size and chemical composition. As a result, they have unequal effectiveness and have different effects.
There are several types of lime fertilizers.
- Fertilizers of industrial production (chalk, limestone, dolomitized limestone, limestone dolomite and dolomite) - sedimentary rocks of the ancient seas containing calcite (CaCO₃) and magnesite (MgCO₃). The differences lie in the amount of magnesium - there is practically no magnesium in the chalk, in dolomite up to 50%. The more Mg is in the composition, the more durable the rock and the worse it dissolves. But such fertilizers are more valuable - precisely because of the presence of an element necessary for crops growing on light soils.
Limestone prepared for quicklime production
From solid limestone rocks, lime and dolomite flour is obtained by crushing, by burning limestone - burnt quicklime, slaked lime (fluff) - by the interaction of quicklime with water. Chalk shows its neutralizing properties faster than lime flour. Lime has a great neutralizing ability, and in quicklime it is almost 1.5 times higher than that of chalk and lime and dolomite flour. Lime acts as quickly as chalk, but is washed out more quickly, so the duration of this fertilizer is shorter.
Extraction of chalk
- Local lime fertilizers - it is drywall (lake lime), limestone tuff (key lime), marl, peat, natural dolomite flour.
Lacustrine and spring lime, marl and peat tufa are deposits of fresh water bodies rich in calcium. Natural dolomite flour is the result of erosion of dolomites, it is found in places of their occurrence. These rocks are soft, do not require grinding, and after application, their action begins faster than that of limestone or dolomite flour. But their neutralizing ability is lower. Marl is recommended for liming light soils, and peat tufa - for introduction into soils poor in humus.
Liming is carried out to deoxidize the soil
- Industrial waste rich in Ca and Mg, in the form of oxides, silicates, carbonates. These include: defecate (waste from the production of beet sugar), blast-furnace slags and sludge (waste from the steel and metallurgical industry), shale ash, slaked lime (waste from the production of bleach), cement dust, belite flour (waste from aluminum production), waste cellulose and paper industry, nepheline flour (apatite processing waste) and others.
Defecate is a valuable lime fertilizer, because, in addition to CaCO₃, it contains organic substances, as well as nitrogen, phosphorus, potassium and some trace elements. But lime fertilizers made from defecation mud are difficult to buy - they are most often used in places of industrial cultivation of sugar beets, which strongly react to soil acidity, because sugar factories are also located there.
Sugar beet grows well in neutral soils
Valuable and shale ash obtained from the combustion of oil shale. This fertilizer has a fairly high degree of acid neutralization, and also contains Mg, P, K, S. Minus - Ca and Mg in shale ash are contained mainly in the form of silicates, so the effect of the fertilizer is slower. In general, according to studies, shale ash and cement dust are 15-39% more effective as fertilizer than the ubiquitous dolomite flour ("dolomite"). When using waste from the steel industry, the possible presence of heavy metals must be taken into account.
How to use lime fertilizers
Lime fertilizers are long-acting fertilizers. Depending on the degree of acidity, the mechanical composition of the soil, cultivated crops, experts talk about 5-10 years. The application of lime fertilizers is usually timed to the rotation of the crop rotation, applying them in front of crops that are most sensitive to high acidity: beets, cabbage, legumes, carrots, celery, cucumbers, onions.
Lime fertilizers are applied for digging
Before applying lime fertilizers, you must first determine their rate. Significant yield gains can be expected when calcium supplements are used in very acidic and acidic soils. In addition to high acidity, liming is necessary with an increased content of iron, aluminum and manganese, as well as with technogenic pollution.
The approximate norms are as follows:
- for those in great need (pH of medium and heavy loamy - 900-1200 g / m2
- for medium requirements (pH from 4.6 to 5.0), half the dose can be dispensed with - 600 g / m² for light soils and 800 g / m² for heavy soils
- at low (pH from 5.1 to 5.5) - 200 and 400 g / m², respectively.
Liming efficiency is increased with the simultaneous application of organic or mineral fertilizers
Liming can be carried out at any time of the year - but it is more intelligent to give the full dose in one step in spring along with deep digging of the soil. Deacidification will be more effective if fertilized with organic matter or mineral fertilizers at the same time. Fertilizers must be evenly distributed over the entire arable layer, therefore, damp, crumpled materials must not be used. To reduce dusting, liming work is best done in calm weather.
In our market, which brings together large online stores, you can find a suitable additive for soil deoxidation on your site. Take a look at the selection of products For soil deoxidation.
Between the planned introduction of full doses of lime additives to reduce the acidic effect of mineral fertilizers, small amounts of lime are added simultaneously with them. To neutralize 1 kg of ammonium sulfate, ammonium nitrate and superphosphate, 1.3, 1 and 0.1 kg of lime fertilizers are required, respectively. If liming is carried out before planting potatoes or root crops, boron must be added along with fertilizers containing calcium. On peat soils - copper-containing preparations. When liming, it is worth increasing the dose of potassium supplements, because calcium comes into conflict with potassium.
By adding the right additives, you can improve your soil
Liming is an important agricultural technique. The introduction of the necessary additives not only reduces acidity, but also improves the structure and absorbency of the soil, sanitizes it, preventing the development of fungal diseases and improving the activity of bacterial microflora. The required doses of basic mineral fertilizers are reduced due to the better digestibility of nutrients by plants, the quality of fruits is improved - taste, keeping quality and transportability. Good harvests to you!
Fertilizers for the lawn: timing, composition, 23 manufacturers
To maintain an attractive appearance of the lawn, it must not only be regularly mowed and watered, but also fertilized. Since the lawn grass is periodically renewed, it is deprived of the nutrients that accumulate in the stems. In order for top dressing to be beneficial, it must be applied in compliance with certain rules.
What substances are needed to feed the lawn
To replenish the lawn flora, the following elements are required:
- nitrogen - accelerates growth, makes the color more saturated
- phosphorus - helps the accumulation of nutrients, improves metabolic processes
- potassium - normalizes electrolyte metabolism, improves resistance to negative environmental influences.
Nutrient deficiencies can be easily identified visually.
With a lack of nitrogen, the grass grows slowly, bald spots may occur. The leaves lose their rich tone, become faded. With an insufficient amount of phosphorus, the plants become very fragile, the greens take on a lilac hue. Lack of calcium is determined by burns on the foliage.
An excess of nutrients, like their lack, can harm plants. Therefore, when applying dressings, it is important to observe the dosage.
An excessive amount of nitrogen makes the grass weak, because of this, resistance to infections and parasites disappears. Plants age and wilt quickly.
Excess phosphorus interferes with other nutrients, so the grass slows down growth. A lot of calcium burns the root system, which can cause plants to die.
To normalize the level of useful elements, you need to water the lawn often (at least 2-3 times a day).
An excess of nutrients can provoke the active growth of more aggressive plants (ryegrass, bent grass).
This will negatively affect decorativeness.
Fertilization by seasons, rules
In order for nutritional mixtures to be beneficial, and not harmful, they must be applied according to the rules, observing the dosage. It is better to fertilize before heavy rain.
If precipitation is not expected, and fertilization is urgently needed, the lawn must be watered abundantly.
Wait until the plants are dry, but the ground is still wet, add organic matter and minerals.
When a drought is observed within two days after feeding, it is necessary to re-water it so that the substances get to the roots.
Fertilizing the lawn in spring, summer and autumn
Fertilizer ingredients and purpose of application differ depending on the season.
In spring, complex feeding with nitrogen, calcium and phosphorus content is necessary for intensive growth, better tillering, bright foliage color. Applying a nutrient mixture will help your lawn recover from winter dormancy. The manipulation is carried out after the snow has completely melted, when the ground warms up, but before the grass begins to grow.
In summer, in hot weather, plants consume large amounts of nitrogen, so fertilizers containing this element are needed. He will be responsible for growth throughout the growing season. The preparations are applied after every 2nd mowing of the lawn.
Fall fertilization is necessary to prepare for wintering. The procedure is performed in the 1st decade of October. The mixture should contain a lot of phosphorus and calcium, which strengthen the roots and increase immunity to infections.
Seasonal application depending on the type of fertilizer
Fertilizers are granular and liquid. The first type is recommended for use in spring and autumn.
Preparations in liquid form are best applied as additional fertilizing in late spring or summer, when the lawn is damaged by frost, trampling, infections or insects.
Liquid fertilizers should be diluted with water and the lawn should be watered. Nutrients are immediately delivered to the roots, so a quick effect is achieved. However, the result will be short-lived.
Regardless of which form of the drug is used, the following rules must be observed when feeding:
- pre-mow the lawn and clear of debris
- use preparations only on wet soil
- after applying top dressing, do not walk on the lawn for 24-48 hours
- do not manipulate in rain or drought, because substances will not be received in full
- strictly observe the dosage
- put on rubber gloves before the procedure, and after it is completed, wash your hands thoroughly.
Dry fertilizers, if the area is small, can be scattered by hand. First, walk along the territory using half of the mixture, then across, adding the rest.It is important to distribute the drugs evenly. If the area is large, it is advisable to use a special spreader.
For even application of liquid mixtures, you can use a watering can with a nozzle. For large areas it is recommended to use pump sprayers.

Fertilizers for the lawn do it yourself
You can make fertilizer from ordinary nettle. It is important that there are no seeds on it. Approximately 1 kg of grass is placed on the bottom of the barrel and 6-8 liters of settled water is poured. The solution is infused for 10 days. It needs to be stirred daily.
Before use, dilute the liquid with water in a ratio of 1 to 10 for irrigation, 1 to 20 for spraying.
By applying fertilizers regularly, without skipping and observing all the rules when applying mixtures, you can get a healthy, beautiful and bright lawn. He will not be afraid of diseases and pests, as well as aggressive environmental influences and mechanical stress.
11 conditions for using lime fertilizers - garden and vegetable garden

To fertilize the soil correctly, you need to follow a few simple tips. There will always be ways to fertilize the soil in the garden or in the vegetable garden without resorting to the use of chemicals. So you can grow natural products that will only benefit, not harm.
It is not without reason that manure is considered the best fertilizer for the garden and vegetable garden. True, it has a relatively low content of macronutrients - such as calcium, potassium and phosphorus with a sufficient amount of nitrogen.
Manure also has a good supply of beneficial bacteria. They convert organic compounds into inorganic ones and thus contribute to the improvement of the fertile qualities of the soil. Regular application of manure saturates the soil with oxygen, which increases the heat capacity of the soil and provides optimal conditions for plant cultivation.
It is recommended to apply manure to the soil not annually, but after two years. This is how long its beneficial effect lasts. But the excessive application of organic fertilizers dries up the soil, making it unsuitable for the development of some plant species.
It is necessary to make from 300 to 400 kilograms of manure per 100 sq. m. And the compost should be taken twice as much. The soil is filled with humus in spring or autumn. And the optimal time for fertilizing the soil with manure is only autumn. During the winter, it will rot a little and give some nutrients to the plants by the spring.
Feces must first be poured into the compost heap, and only then into the soil. This is done because they can contain many substances harmful to humans.
The most common inorganic plant fertilizer is common ash. Eggshells are also used as fertilizer. Before entering into the soil, it is thoroughly crushed.
The use of ash is justified to lower the acidity of the soil. The ash obtained after burning fuel such as peat does an excellent job with this task. More valuable ash is obtained after burning brushwood, especially deciduous trees.
It is not recommended to add ash along with manure, as this will lose a large amount of nitrogen. This combination can be carried over to spring. But bone and dolomite flour are perfectly combined with organic fertilizers. Again, when applying lime fertilizers, you must observe the measure, since excessive application of lime will change the acidic characteristics of the soil and thus the plants will stop developing.
If the soil is peaty, then it is better to add a small amount of river sand and clay to it, this brings a tangible result, although it is somewhat difficult to add such components to the soil.
Do not use shale and peat ash when it has a rusty color. This indicates the presence of harmful impurities. Ash in some cases is replaced by the introduction of a small amount of potassium sulfate.
What fertilizers do plants need
For the normal development of plants, all mineral elements are necessary, but the following are worth highlighting:
1. Nitrogen. It is used to form greenery. Nitrogen is especially needed for plants from the beginning of the growing season.
2. Phosphorus improves the formation of the ovary, flower. Therefore, this element is extremely important for those crops that bear fruit - for example, cucumbers, tomatoes, and other vegetables.
3. Potassium promotes active plant growth. In addition, it increases the resistance of crops to pathogens.
4. Calcium regulates the acidity of the soil.
Both the lack and excess of minerals have a bad effect on the development of plants. So you need to achieve the optimal proportions of all nutrients in the soil in order for the crops being raised to give a good harvest.
Microelements are also vital for the normal development of plants. They are found in the soil in the smallest quantities, but, despite this, they affect plant growth no less than macronutrients.
To fertilize the soil, you can use the following fertilizers:
• Urea. It is rich in lots of nitrogen. It is enough to add a kilogram of urea per one hundred square meters.
• Ammonium sulfate. You need to apply from 2.5 to 4 kg of fertilizer per hundred square meters. To neutralize the increased acidity, it is advisable to mix it with chalk.
• Superphosphate - applied in autumn or spring. Two to three kilograms of fertilizer are enough for a hundred square meters.
• Potassium chloride has an adequate amount of potassium. Fertilizer is applied in the fall - 1-2 kg per hundred square meters.
• Potassium nitrate is dissolved in an amount of 30 - 40 g per 10 liters of water. The resulting solution of 0.5 liters is sufficient for one plant.
The methods of application of mineral fertilizers are indicated on the packaging.
