A Brief Review of Phosphate Rich Organic Manure, 2016

Abstract

Abstract

The article starts with the classification of plant nutrients and gives a brief about mineral fertilizers and explains the mechanism of phosphate-uptake by plants. 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).

Keywords: Bacillus megatherium, varphosphaticum, Phosphate-uptake, PROM
