摘要: Inorganic phosphorus (Pi) usually controls the P availability in tropical soils, but contribution of organic (Po) should not be neglected, mainly systems with low input or management that promote matter accumulation. The aims this study were to evaluate changes Po fractions over time soil fertilized and cattle manure correlate forms available extracted by anion exchange resin. experiment was carried out under field conditions, a sandy-clay loam Haplustox. experimental design 2 × 9 randomized complete block factorial design, which first factor application (20 t ha-1) absence, second sampling times (3, 7, 14, 21, 28, 49, 70, 91, 112 days) after incorporation. Labile, moderately labile non-labile determined material each sampling. Manure fertilization increased levels total P, did affect fraction proportions relation P. On average, 5.1 % labile, 44.4 50.5 fractions. Available (resin P) more affected soluble Pi rather than forms. varied randomly no defined trend samplings; for reason, data fit any mathematical model.
