Phosphate Rich Organic Manure (PROM) has been in the frame of organic farming since last two decades and is challenging synthetic chemical fertilizers like DAP, MAP, SSP, and Nitro-Phosphates. PROM is essentially high-grade rock phosphate mineral in fine size along with well-matured organic manure. Bacillus megatherium, varphosphaticum (phosphate solubilising bacteria), Azotobacter (nitrogen fixing bacteria) etc. may be added to improve the efficacy of PROM. Well-matured organic manure has C:N ratio at 20:1. The aim is to illustrate step-by-step process of manufacturing phosphate rich organic manure (as a marketable product)with government specifications as mentioned in fertilizer control order (FCO).

Straight chain saturated fatty acid anions are envisaged to form compact adsorbed patches on the mineral surface, which are more effective in imparting surface hydrophobicity to the minerals than the loose/fluffy patches formed by unsaturated fatty acid anions that are bent at the double bonds. Addition of detergents or certain hydrotropes along with fatty acid/soap collectors reduces the consumption of fatty acids/soaps and thereby improves selectivity of mineral separation.

Nepheline syenite mineral2 contains 5.58% K2O, 8.23% Na2O. The K in nepheline Syenite is not in readily water soluble form. Proof of concept studies are conducted to see if fine sized nepheline syenite mineral can be used as source of K nutrition with the back ground of organic manure in the bio mass production of Spinach3, Spinacia oleracea. These results are compared with laboratory grade KCl on equal K2O basis.
