Phosphor is an essential nutrients needed by plant for growth and production. Treating the plant with organic matter such as plant residue or compost will improve soil quality, especially increasing P-availability. Both plant residue and compost contain of organic compounds which mobilize phosphate in the soil. This research attempts to evaluate the influence of organic compounds extracted from plant residue and compost on P-available in rock phosphate and soil. Result indicates that organic compounds extracted from plant residue and compost may influence the dissolution of P from rock phosphate. The influence of organic compounds from compost is better than its compost extract in improving P-availability in soil. © 2014 AENSI PUBLISHER All rights reserved.
