SSP

SSP is a water soluble quick-acting fertilizer and its available phosphorus (AP2O5) content is over 16%. The product can be used as base manure, topdressing, seed manure and raw materials for blending compound fertilizers. This product is extensively applied to varieties of grain crops and cash crops including paddy, wheat, corn, sorghum, cotton, gourds, fruits and vegetables. It is extensively suitable to many soils of different properties such as red earth, yellow earth, brown earth, yellow wet earth, black earth, cinnamon earth and purple earth etc. It is especially appropriate for phosphorus-lacking areas in north, northwest, and northeast China.
