Ammonium sulfate granulated, Rivne region.

Application of nitrogen-sulfurgranulated fertilizers (N21:S24)
It has been established that each culture has its own physiology of mineral nutrition with respect to sulfur and nitrogen compounds. Physiology of mineral nutrition of winter rape requires a ratio - N:S= 5-10:1. For grain crops and corn, this ratio should be - N:S= 16-20:1, respectively. Only if this ratio is observed, the problem of optimizing mineral nutrition with sulfur and nitrogen compounds is solved. Only under such conditions, cultures are able to synthesize protein compounds normally, their rate of assimilation of nitrogen compounds increases.
Granular nitrogen-sulfur fertilizer is a highly effective nitrogen fertilizer, the use of which ensures high agronomic and economic efficiency of growing the main agricultural crops.
Granular nitrogen-sulfur fertilizer is obtained by granulation of crystalline ammonium sulfate with the addition of an aqueous solution of humates.
The main raw materials used for the production of fertilizer are:
-ammonium sulfate;
- humates (potassium or sodium salt of humic acids).
Ammonium sulfate granulation is carried out by pressing intwo-roll granulators, due to which it does not clump together!
The technical conditions of TU U 24.1-37685405-001:2011 for nitrogen-sulfur fertilizer are registered.

The most important advantages of granular nitrogen-sulfur fertilizer compared to crystalline ammonium sulfate are:
Improved physical and mechanical properties of fertilizer:
- uniform granulometric composition.
The mass fraction of the commodity fraction size:
• from 3 to 4 mm is at least 90% (with a norm of 80%),
• from 1 mm (that is, dust) is only 2%.

the indicator of the dynamic strength of the granules is at the level of the indicator for potassium chloride and is 80-90% with a norm of at least 80%.
- friability (the product does not clump together, after long-term storage, the granules do not break down, even slightly clumped ones crumble).
Improved environmental performance. Nitrogen-sulfur fertilizer has a neutral pH value:
The pH of a 10% aqueous solution of nitrogen-sulfur is 5.8-6.4 against the value for crystalline sulfate of 4.6-4.8. Thus, by using humates in the granulation process of ammonium sulfate, we improve the ecological indicators of the fertilizer, namely, we change the physiological acidity of the fertilizer; The ammonium form of nitrogen, compatible with sulfur, prevents the accumulation of nitrates by 3 times, reduces the content of radionuclides in plants by 2 times, heavy metals by 1.7 times. Can be used in contaminated areas.
Improved agro-chemical benefits:
• § homogeneity of introduction (granules are dispersed by technical means homogeneously, evenly);
• § granular form provides the possibility of using nitrogen-sulfur fertilizer as a component of fat mixtures. Unlike crystalline, humate-neutralized nitrogen-sulfur fertilizer does not enter into a chemical reaction with other components of fat mixtures and provides a stable chemical and granulometric composition;
• § absence of burns on plants after application.
Use of humates in nitrogen-sulfur granulated fertilizer:
• § increases the digestibility of nitrogen-sulfur fertilizer nutrients by plants by 30-50%;(//tractor-service.com)
• § accelerates seed germination;
• § contributes to the development of the root system;
• § increases the resistance of plants to adverse environmental factors: low temperature, poor lighting, insufficient moisture;
• § increases plant resistance to diseases and pests;
• § stimulates the development of all soil microorganisms, which contributes to the intensive recovery of humus;
• § increases the efficiency of assimilation of mineral substances and trace elements by plants;
• § improves the quality of grown products: under their influence, the content of vitamins, protein, starch, nucleic acids and sugar in plants increases; by grain: increase of gluten by 3%;
• § humates contribute to the economical consumption of moisture during the daytime hot period and strengthen the protective reaction of plants against the effects of high temperatures and drought, are regulators of the water regime in the soil;
• § bind products of man-made pollution: compounds of mercury, lead, pesticides, radionuclides, etc. and prevent their entry from the soil into the plant and thereby ensure the ecological purity of the products.
• § humates, which are contained in fertilizer, improve the physical, chemical and biological properties of soils, perform a protective (protective) function, are able to restore the fertility of poor, exhausted, technogenically disturbed soils.
Granular nitrogen-sulfur fertilizer is recommended primarily for crops:
• § demanding on sulfur (rape, cabbage and other cruciferous crops, buckwheat, winter and spring wheat);
• § which prefer the ammonium form of nitrate nitrogen (potatoes, sugar beets, fodder crops);
• § which grow better with a slightly acidic reaction of the soil solution (potato, flax, tea, sunflower, carrot, tomato, sorrel, parsley, turnip, radish, pumpkin, zucchini, radish, gooseberry, raspberry).
It is recommended to apply nitrogen-sulfur fertilizer both in the main application under pre-sowing cultivation, which makes it possible to evenly distribute the fertilizer over the field, and during top dressing.
