An excellent source of phosphorus for crops, GSSP also contains substantial quantities of sulfur, calcium and micronutrients. Granular Single Superphosphate (GSSP) is an excellent source of phosphorus for crops and it also contains substantial quantities of sulphur, calcium and micronutrients. The effectiveness of this fertilizer stems from the highly water-soluble product_emphasizephosphorus content (as P2O5). Application of GSSP begins and maintains supply of this key nutrient to the growing crop. Single Superphosphate (SSP) has key benefits for crops. SSP is a highly efficient fertilizer as the water-soluble phosphate it contains is very quickly and easily absorbed by plants. SSP also contains a high amount of soluble sulfur which makes it ideal for soils with a sulfur deficiency. The calcium in SSP helps strengthen plants and improves disease resistance and frost hardiness. SSP can be applied directly or used in the production of granular compound fertilizers. It is available in both in granular and powder form. Also available with TE by request.
