Charging farm compost with Mussoorie rockphosphate with and without pyrite increased the citrate soluble P. Much of inorganic P was changed into organic form during composting. Different inorganic phosphorus fractions were found in the decreasing order of abundance as Ca—P, occluded Fe—P, Fe—P, Al—P and occluded Al—P. Incorporation of rockphosphate also improved the quality of compost by increasing the contents of nitrogen, calcium, magnesium and micronutrients.
