Abstract


A research about organic matter role on P desorption in Andisol was conducted in soil laboratory of Agricultural Faculty, Andalas University Limau Manis Padang. The objective of this research was to find out the ability of organic matter to change retained- or fixed-P into available-P in Andisols. This research was designed as completely randomized design (CRD) with 5 levels of chicken manure consisting of 2, 4, 6, 8, and 10 ton/ha by 3 replications. Based on laboratory analysis, the soil (Andisols) had pH 5.65, OC 2.33%, N-total 0.26%, available-P 56.94 ppm, and potential-P 60.38 mg/100 g soil. While chicken manure had OC 21.45%, total-N 5.60%, total-P 33.19 mg/100g and C/N ratio 3.83. The results showed that desorpted-P increased by increasing amount of chicken manure applied.

Key words: fixed-P, available-P, desorpted-P
