Production of phosphorus rich organic manure (PROM) by
composting of press mud and distillery waste with rock phosphate
into a value added product standardized to contain 10.4% P2O5 with
22% moisture is a highly promising, natural, better and cheaper
substitute of di-ammonium phosphate (DAP). Phosphate Rich.
Organic Manure.
Phosphorus is required by all plants but is limited in soil, must be
added to soil for the extensive plant growth that is desired for crop
production. Phosphorus was first added as a fertilizer in the form of
single super phosphate in the mid-nineteenth century, following
research at Rothamsted Experimental Station in England.
