NPKS 21:10:10:2
NPKS 21:10:10:2 is a highly effective complex mineral fertilizer each grain of which contains 21% of nitrogen, 10% of easily available phosphorus, 10% of potassium, and 2% of sulphur.
This fertilizer is good for reclaimed soils with medium concentration of movable forms of phosphorus and potassium as the fertilizer itself has high concentration of nitrogen and medium concentration of phosphorus and potassium. The ratios N:P and N:K as 2:1 make NPK 21:10:10:2 a good presowing fertilizer for grain and tilled crops. Sulphur applied together with nitrogen takes part in protein synthesis processes, increases protein concentration in grain, improves the baking quality of grain. Sulphur increases oil content in the seeds and makes the plants more resistant to low temperatures, drought, and illnesses.
Combination of nitrogen, phosphorus, potassium and sulphur in each grain secures equal distribution of nutrition elements in top soil that helps on simultaneous emergence of seedlings and rapid plant growth.
According to its quality characteristics NPKS 21:10:10:2 was among “TOP 100 Best Russian Products – 2004”.
This fertilizer can be used as a basis for bulk blends. It has good physicochemical characteristics: the material doesn’t cake and is not hygroscopic.
