Rock Phosphate Enriched Compost:: Optimization of factors

by Tariq Aziz

Phosphorus plays an important role in a number of processes in plants, especially in photosynthesis, carbon metabolism, membrane formation, energy generation, glycolysis, respiration and nitrogen fixation. Although total P in the soils are high but their availability to plants is too low to meet the requirements so viable strategies are needed to solublized the inorganic P and to use the RP (insoluble source of P) to decrease the dependence on costly chemical fertilizers in crop production . For the transformation of insoluble phosphorus (PR) to soluble form, composting technology would serve as breakthrough and provided optimal conditions. The objective of the study was to optimize the RP ratio, time and temperature conditions for maximum solublization of P by composting. This study was undertaken to evaluate the potential of composting technology to solublize the rock phosphate in soil and also to develop optimum conditions for better release of available P for growth and development of crop plants.
