Resumo: | ABSTRACT Phosphorus (P) availability is related to soil sorption capacity and is relevant to planning P fertilization and evaluating its residual effect. The aim of this work was to evaluate the P availability to maize plants after different incubation times of six soils from Paraíba state. For this, four doses of P (0, 100, 200 and 300 mg dm-3) were applied in samples of six soils for 0, 30, 60, 90, 180, 240 and 360 days. After the incubation time, the soil samples received fertilization with macro and micronutrients and were cultivated with maize for 35 days, when they were harvested and analyzed to verify dry matter and P content in soil. The increase in the time of contact of P with the soil decreased P availability to plants; however, the formation of non-labile P was negligible in most soils. After 360 days of incubation, between 26 and 71% of P applied at the highest dose was recovered.
