Single Superphosphate is produced by grinding and acidulating rock phosphate. Grinding increases the reactivity, and acidulation with sulfuric acid makes the phosphate water-soluble, which enables the plants to absorb the fertilizer. The high water-solubility of the P2O5 content in Single Superphosphate increases the effectiveness of the fertilizer.

Because of the use of sulfuric acid in its production, Single Super Phosphate contains a large amount of soluble sulfur, which makes it ideal for soils with S-deficiency. There is also a considerable amount of Ca in the product.

Single Super Phosphate (SSP

Granular Single Superphosphate is used both for direct application and for bulk blending; it has a variety of uses:


For crops with high S requirements, such as legumes (alfalfa, clover, soybean, etc.) and cruciferae (canola, rapeseed);


For crops with high nitrogen requirements (corn, cotton), which must have adequate S to optimize their N utilization;


In sulfur-deficient soils, including soils with low organic matter content, cold and wet soils, and light textured and sandy soils;


It is ideal for drilling with the seed in grain legume crops (such as soybean) that require ample supplies of P and S;


It is ideal for top-dressing of pastures - S promotes legume production, thus raising both the forage quality and the N status of the pasture.
