Ammonium Sulphate (21% N)

This 21% nitrogen fertilizer is one of the most valuable nitrogen sources, particularly in sunflower and cereal production. This is because the plant takes up its nitrogen gradually while also receiving sulphur, which improves grain and oil quality. In wheat and barley it supports protein formation, grain filling and tillering. In orchards, especially those showing weak growth, it feeds the trees in a balanced way and increases shoot growth and fruit formation. It can be used both as a basal dressing and as a top dressing, and it can also be applied through drip irrigation systems.
