I will sell ammonium sulfate, ammonium sulfate n-21; s-24, Cherkasy oblast.

One of the nitrogen-sulphur mineral fertilizers widely used in agriculture, contains 21% nitrogen in ammonium form and 24% sulfur.

It is a crystalline salt of white, yellowish or gray color, well soluble in water.
Fertilizer is physiologically more acidic than ammonium nitrate. It is recommended for application on non-acidic (saturated with bases) soils and on acidic soils with liming.
Can be applied in autumn. Fertilizer is valuable for its sulfur content. Slow-acting fertilizer for main or pre-sowing application.
When applied to the soil, ammonium sulfate quickly dissolves. The ammonium group is absorbed by the soil absorption complex, which keeps nitrogen from leaching. Thanks to good sorption in the soil, it is not washed away and is the only source of nitrogen for plants for a longer period.

Ammonium sulfate, thanks to 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. Can be used in contaminated areas.(//tractor-service.com)
Taking into account the physiological acidity of ammonium sulfate, plants absorb a cation from ammonium sulfate faster than an anion, because plants need more nitrogen than sulfur. Acid residues accumulate in the soil and this leads to acidification of the soil, which must be further deacidified.

It is recommended to apply to crops that are sensitive to a lack of sulfur: cruciferous vegetables (rape, turnip, mustard, turnip, cabbage),corn,potato, onion, garlic, rye, oats; and on soils poor in sulfur.

It is advisable to use when growing rice, cotton, tea, subtropical crops that are cultivated in conditions of excessive moisture, as the fertilizer is slowly washed out of the soil, as well as for cruciferous crops (winter rape, spring rape, oil radish, etc.), legumes and oil crops that require sulfur nutrition.

If the fertilizers used for the mainapplication of fertilizer did not contain sulfur, then you can feed potatoes with ammonium sulfate, preferably 8-15 days after planting the tubers. Scattered fertilizers are wrapped in the soil during mechanical loosening.
A one-time application of ammonium sulfate even on podzolic soils does not significantly affect the change in the reaction of the soil solution, and the systematic application of this fertilizer on podzolic and podzolic soils leads to acidification of the soil solution. This feature of the fertilizer is taken into account when using it, simultaneously liming the soil.
On chernozems, the use of ammonium sulfate does not have a negative effect on plant development.
