SINGLE SUPER PHOSPHATE ( SSP )
MOLECULAR FORMULA: Ca(H2P04)2H20
STANDARD APPLIED: GB 20413-2006
CHARACTERISTICS: In powder or granule with light acidity.
USAGE: It can be used for supply Of phosphorous, calcium and sulphur elements etc. to plants. It can steady nitrogen and reduce nitrogen lose, and speed the nutrients'synthesizing of nitrogen, sulphur, calcium and silicon elements etc. It also can be used as raw material of compound fertilizers.
USING GUIDE: When using it as a base fertilizer, apply 10 to 80 kilograms per mu subject to the soil texture; when using it as a complementary fertilizer, apply 40 to 50 kilograms per mu, and apply it around the roots not directly to the roots.
