Phosphorus is required by all plants but is limited in soil, creating a problem in agriculture. In many areas phosphorus must be added to the soil for extensive plant growth that is desired for the crop production. Greenfield Phosphate Rich Organic Manure (PROM) is a type of organic fertilizer used as an alternative to diammonium phosphate and single super phosphate. Greenfield PROM is also known as a Green Chemistry phosphatic fertilizer. Research indicates that Greenfield PROM may be a more efficient way of adding phosphorus to soil than applying chemical fertilizers. Other benefits of Greenfield PROM are that it supplies phosphorus to the second crop planted in a treated area as efficiently as the first.
