Basilisk pasture on the P bioavailability to the following soybean crop. Low-productivity pasture, planted on an Oxisol in an experimental field at Embrapa Cerrados, was divided into three strips, each of 1.5 ha and fertilized by broadcasting annual applications of 0, 20 and 40 kg ha(-1) of P2O5 for four years. After the pasture was desiccated with herbicide, soybeans were sown and fertilized with 0, 50 and 100 kg ha(-1) of P2O5 applied within each strip, making a total of nine (3x3) P treatments. Residual available P content (Mehlich-1 and resin) from the pasture fertilization was lower than from soybean fertilization. However, the bioavailable residual P from the pasture, determined by P accumulated in plants, production of dry matter and grain yield, had similar availability to inorganic P applied to the soybean. Early P fertilization applied to pasture is technically feasible and can be used to maintain the pasture: it is recommended to replace corrective fertilization for following soybean crops. specialized Urochloa Phosphorus availability Phosphorus accumulation Residual effect No-tillage BRESIL 076 38 2 571-580 2017 1676-546X https://www.documentation.ird.fr/hor/fdi:010070267 10.5433/1679-0359.2017v38n2p571 1676-546X [F B010070267] https://www.documentation.ird.fr/hor/fdi:010070267 https://www.documentation.ird.fr/intranet/publi/2017/07/010070267.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-07-26 2018-01-02 fdi:010070267 fre
