Polyphosphates in Agriculture

Ammonium polyphosphate is one of the most often used phosphoric fertilizers (Corbridge, 1980). It was found to be equally effective when compared with single superphosphate and diammonium phosphate for increasing the yields of wheat and maize and for increasing the available phosphorus content in soil during field experiments (Sharma and Singh, 1998). 

However, the excess of phosphates and PolyPs in soil due to technogenic pollution and the use of fertilizers has a great influence on the transformation of mineral and organic compounds in soil, the composition of soil microbial communities, and finally agriculture productivity (Kudeyarova, 1993).
