SSP

SINGLE SUPER PHOSPHATE (SSP)

SSP – A multi nutrient fertilizer containing water soluble (14.5%), sulphur (11%) and Calcium (21%). SSP is applying as basal fertilizer with other chemical as organic fertilizers. It has tremendous impact on plant growth, yield of crops and also assist in maintaining soil health and protection against pest and diseases.

Since India is an agricultural economy the principal use of SSP is evident and highly demanded fertilizer, mostly used at the time of preparation of land. SSP being called as a poor man's fertilizer (price wise), is a very good option to use phosphate fertilizer, which helps the sulphur deficiency in soils (as Indian soil is 40% sulphur deficient). It also reduces the burden on the exchequer by reducing the outflow of subsidy to the import of DAP.

The various crops which require more sulphur and phosphate are like Oilseeds, Sugar cane, Fruits, Vegetables and Tea etc.

Advantages of SSP Fertilizer:-

Provides 15% of the total phosphate requirement of the country.
Lowest price per kg, preferred by small and marginal farmers.
Multi-nutrient fertilizer containing P2O5 as primary nutrient and Sulphur and Calcium as secondary nutrients.
It is the cheapest source of Sulphur for the soil.
Only phosphatic fertilizer utilizes Indian rock phosphate deposits.
Least foreign exchange per unit of P2O5.
Utilizes acid effluent from other chemical industry and thus reduces the nation's cost of effluent disposal.
SSP provides 14.5% WS P2O5 and 16% CS P2O5.
SSP can help to convert unavailable nutrient in available form in the soil.
SSP can help to improve the soil’s physical as well as chemical properties.

Agronomic Importance:

SSP helps in improving root growth and development which is most important for uptake of plant nutrient and water.
For Leguminous crops like groundnut, use of SSP, ensures a large number of nodules on the roots, which fix atmospheric Nitrogen directly into the soil and also increase Nitrogen uptake.
SSP improves soil aeration and increase water holding capacity of the soil and increase root growth which increase crop yield.
The oil content of Groundnut and other oil seed increases. The quantity and quality of oil seeds crops increases
In Sugarcane, the sugar content increases, which provide more production and monetary benefit to the farmers
SSP increases the resistance power of the plants against attack of pest and disease.
SSP increases protein content in pulse crop
SSP helps to leach excess water from the root zone and prevent yellowing of the crop
SSP improves storage capacity of the product
SSP also act as soil reclaiming agent.
