SSP, irrespective of the fact that it contains following three plant nutrients, is still perceived as low analysis fertilizer:

1) Phosphorus as P2O5 : 14-22%;

2) Sulfur as SO4 : 11-12%; and

3) Calcium as CaO : 18 - 20%

It has low salt index of 8, and does not change pH when applied to soil. Sulfur and Calcium are well recognized secondary plant nutrients in science.

Single Super Phosphate (SSP), straight Phosphate fertilizer, is recommended for soil application at the time of sowing. Water Soluble phosphate content in SSP is more than 85% and is easily adsorbed by crops for better yields. It is cheapest source of Phosphorus and is very popular among farming community.

SSP is sulphur containing fertilizer which is extremely essential for oil containing crops such as Cotton, Rapeseed-mustard, and Groundnut etc. Sulphur nutrient is also required by pulses and all other crops including fruits & vegetables. Significance of SSP is established beyond doubts as "S" (Sulphur) comes almost free of cost when farmer purchase it for Phosphorus.

Role of Calcium in crop growth is well established. SSP is the richest source of calcium. Additional application of calcium enhances its deposits in soil and improves soil health for high yields. Calcium availability also comes free of cost like sulphur when farmer purchase SSP for phosphorus.

SSP is produced both in Powder and Granulated form for ease in application. Performance of powder and granulated forms are same. Granulated form is preferred by farmers using mechanized Fertilizer Drill.

Ammoniated Single Super Phosphate (ASSP)

ASSP is produced by Ammonisation of SSP. Purpose of Ammonisation are:

1) Prevent rotting of bags in case of long storage period and maintain product quality

2) Reduce curing period significantly.

3) Improve granule shape and quality

4) Nitrogen (N) is added as an additional nutrient, although in small quantity

ASSP is most preferred phosphate fertilizers by farmers in Uzbekistan due to specific soil conditions and its value for money. Nutrient content and other characteristics in ASSP, offered under our brand "OLTIN" brand and duly endorsed by Indorama are:

1) Nitrogen as N per cent by weight minimum : 1.0

2) Phosphorus as P2O5 per cent by weight minimum : 17.0

3) Sulphur as SO4 per cent by weight minimum : 11.0

4) Calcium as CaO per cent by weight minimum : 18.0

5) Bulk density Kg per Square meter : 961

6) Critical Relative Humidity per cent at 30 degree C : 93.7

ASSP produced by Indorama Kokand plant will be in granulated form and supplied in 50 Kg HDPE bags. It shall also be supplied in bulk, to large farms and Clusters in Uzbekistan.
