Corrective and maintenance phosphorus fertilization on sugarcane yield in Oxisols

Abstract The objective of this work was to evaluate sugarcane (Saccharum spp.) yield in response corrective and maintenance phosphorus fertilization Oxisols. Two experiments were carried out randomized complete blocks with four replicates. In the treatments, 150 kg ha-1 P2O5 broadcast incorporated before planting. 40 per year applied over trash blanket. All except control, fertilized 170 planting furrow. first experiment a expansion area second, replanting area, Oxisols low high availability, respectively. experiment, increased cane 13.4 Mg for plant 14.6 average ratoon crops, whereas 17.7 8.1 crops treatments without fertilization, second there no significant differences between regarding yield. Corrective should be considered areas where soil availability is limiting.
