Phosphorus availability as influenced by different organic manure in a red soil amended and time of incubation
Author(s): Yogesh Pal, Nijesh P and AK Ghosh
Abstract: A laboratory incubation experiment to investigate at the effects on phosphorus release of the addition of organic manures to red soil. Organic manure was added at the different rate. After the incubation, P values in control and amended soils were used for phosphorus availability and by a extraction procedure. The relative contribution of available phosphorus indicating that organic manure increased P in the red soil. In soils amended with different organic manures. A phosphorus mineralization study was conducted in net house Department of soil science and agriculture chemistry Institute of Agricultural Sciences Banaras Hindu University, Varanasi-221005, (U.P.), India 2013-14.Five organic manure FYM, oilcake, poultry manure Pig manure and rice straw in a wide range of C/N and C/P ratio. Were added to the soil sample at the rate of 4, 40, 80 t ha-1.The sample were incubated for 2, 72, 168, 336, 480, 1440, 2160 hours at constant temperature and moisture. The extractable P was determined after the each incubation period. The extractable P calculated in mg kg-1. Mineralization of P comparison between the unamended soil and amended soil with organic manures.
