Fertilizer nitroammofosk: instructions for use and effectiveness

Fertilizer composition

The chemical composition of superphosphate called nitroammophoska is represented by the following formula - NH4H2PO4 + NH4NO3 + KCL. The formula encodes three components known to all: nitrogen, phosphorus, potassium.

It is this ratio that can favorably and quickly influence the growth of culture. Superphosphate release form:

• gray granules;
• mineral liquid substance.

It is customary to apply the agrochemical in the form of granules during the main sowing or pre-sowing work, but the mineral liquid is better suited for foliar feeding of both garden and garden plants. Nitrogen, as one of the three components, is presented in this fertilizer in an easily assimilable form, which allows it to be used for a wide range of crops. Phosphorus, as the main element of growth, is represented in three types of nitroammophos:

• Monocalcium phosphate;
• Dicalcium phosphate;
• Ammonium phosphate.

Such a triad of components allows phosphorus to be easily and quickly transformed into the form that is necessary for the nutrition of a particular plant. This is precisely what is explained by such a quick effect after applying a useful fertilizer.

Pros and cons

Despite the high popularity of superphosphate among experienced agricultural technicians and fans of growing potatoes or seedlings, before using the tool, you should learn about the pros and cons of its use. Nitroammofosk, like any other mineral component, has both advantages and disadvantages. What are the advantages of using:

1. Long storage period of fertilizer - throughout the entire shelf life, the granules remain absolutely crumbly.
2. High concentration of growth stimulants. The total part of active substances in superphosphate is at least 30% of the total weight.
3. Unlike one-part fertilizers, nitroammofosk fertilization is less fixed by the soil.
4. One small granule contains three active elements at once, which means that you will have to spend less on the purchase of fertilizers in general.
5. Easily soluble in aqueous media.
6. Depending on the type of crop, the yield with the use of a growth stimulator can increase from 30 to 70%.

What unfavorable application of this type of fertilizer can bring:

1. Nitroammofoska is an inorganic agrochemical.
2. Inadequate fertilization can lead to the accumulation of nitrates in the soil.
3. The substance is highly flammable and even explodes.
4. The relatively short shelf life of the fertilizer.

Popular types

Despite the fact that the composition always has the three above-mentioned components, its individual types are distinguished depending on the concentration of nitrogen, phosphorus and potassium. Different brands of nitroammofoska with different ratios of components are necessary for more effective use of the product on different types of soil. Consider the fertilizer brands:

1. NPK 16:16:16. A composition with such a ratio assumes the presence of all three components in equal proportions. Thus, the total proportion of active substances in the total mass reaches 48%. The scope of application is quite extensive: almost all plants in the pre-sowing and post-sowing period.
2. NPK brands 15:15:20, 13:13: 24,8: 24: 24 contain an increased proportion of potassium. It is effective to use such a superphosphate composition on chernozem soils to obtain high yields of potatoes, grapes and a variety of seedlings.

Depending on the type of soil and the crop being grown, you can independently choose a brand of an agrochemical with the right proportion of the main components.

Terms of use

The substance has an increased explosiveness, therefore the first rule for use is to avoid heating the granules of nitroammophoska. The optimal storage place is a brick or concrete building, where the average daily temperature does not exceed plus 30. The air humidity should not exceed 50%. Do not store superphosphate with other formulations. It is strictly forbidden to use heating devices and open flames near the storage area. The optimal storage period for top dressing is 6 months. For transportation, use land transport, and transport the substance both packed and in bulk.

If we talk about the types of soils and methods of using granules, then the best potato yields can be obtained from superphosphate on chernozems and alumina. The denser the soil, the longer it takes for the fertilizer to react. Therefore, on heavy soils, nitroammofosku fertilizer should be applied in the fall, and for light soils, spring feeding of seedlings is optimal.

What plants can I use

Fertilizer nitroammofosk is used by farmers for more than a dozen years. At the same time, some are wary of such a composition, since feeding during the entire growing season is fraught with the accumulation of nitrates in the soil and plant tissues. However, if you stop applying fertilizer in advance, then the harvest will be as "healthy" as possible. Fertilizer can be used with many crops. Fertilization chart for the most popular crops:

• potatoes - 20 grams per square meter;
• tomato seedlings - 20 grams per square meter;
• berries (currants and gooseberries) - it is enough to apply 65-70 grams of fertilizer under one bush;
• raspberries and blackberries - 35 grams per square meter;
• fruit trees and top dressing of grapes - 70-90 grams.

The fertilizer must be mixed with the soil around the trunk. This instruction is advisory in nature, since the exact dose of fertilization depends on the type of soil and the growing season of the crop. The use of such fertilizer on plantations and a small summer cottage saves money and time, since the concentration of the composition is quite high. Therefore, to feed even a large area, much less nitroammophoska will be required than other mineral fertilizers.
