In OASI N 11 S15 mineral nitrogen (from ammonia sulphate and urea) is mixed with organic one, to obtain a very efficient fertilizer. OASI N 11 S15, contains three forms of nitrogen in a balanced ratio (organic, urea, ammonical) and sulphur.
OASI N 11 S15 also contains organic carbon and vegetal amino acids improving the development processes of plants as they are the fundamental bases of every biological molecule.
There is no loss of nitrogen due to leaching (economical and environmental advantages) neither negative effects such as tissue softening, development of fungus, etc. The presence of sulphur and plant amino acids improves the quality of production.
