AS 21 Ammonium sulphate can be used as a universal fertilizer for all field crops: autumn and spring cereals, industrial and stoop crops, meadows and vegetable and fruit production. It is especially recommended for fertilizing cruciferous plants (spring rape - early-spring, pre-sowing fertilization, downy grass, mustard seeds, cabbage, cauliflower, kohlrabi), legumes, potatoes, onions, leeks, garlic and horseradish, and autumn foliar fertilisation. The use of AS 21 ammonium sulphate is recommended above all before sowing or before farming activities, mixed with the soil or as a foliar object before the expected rain.
