NK+S 20:3+22S is a basal, starter, foliar and side/top dress fertilizer. It is suitable for all types of soils and all climate zones during the entire growing season as well as for crops with high nitrogen and Sulphur demand. It is primarily intended for the fertilization of Brassicaceae (cabbage, rapeseeds, radish, mustard), garlic, onion, buckwheat, pea, alfalfa, blueberry and crops which prefer nitrogen in ammonium form to nitrate form (potato, sugar beet, forage). In view of the applying high amount of nitrogen, cereals, winter and summer crops require to receive sufficient Sulphur. Frequency of foliar application is about 1-3 times, but it depends on crop itself and its growing season. Granular ammonium sulphate can be mixed into pesticide working solutions and other agrochemicals, not exceeding concentration and doses of fertilizer and before mixing them up it is required to run the compatibility test. Granular ammonium sulphate may be blended with the most widely used mineral fertilizers prematurely or just prior to applying. It is inadvisable to mix ammonium sulphate with organic fertilizers and lime.
