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

Phosphate fertilizer placement at sugarcane (Saccharum spp.) establishment can strongly influence the distribution of soil P pools over crop cycles, and has a great influence in the availability of this nutrient to plant uptake. Our main objective was to evaluate sugarcane yield as well as changes in the distribution of soil P pools, under phosphate fertilizer sources and their management, over two years of sugarcane cultivation. The experiment was established in August 2013 with two phosphate sources (TSP (triple superphosphate) and RP (Bayovar rock phosphate)) and three application methods: as broadcast, at planting furrow and combining half broadcast/half plant furrow, all at the rate of 180 kg ha−1 soluble P2O5 being applied at crop establishment. Sugarcane yield and P uptake was evaluated, and soil was sampled after harvest in August 2015 to analyze P fractions. Substantial amounts of P derived from fertilizers were accumulated as inorganic and/or organic moderately labile P. Broadcast application of TSP was not able to enhance total P in 0–40 cm layer compared to control treatment. In general, TSP was more effective to supply P for sugarcane and keep more of this nutrient in all labile fractions in the soil. However, the potential residual effect of RP (Ca-P) is expected in the following years, slowly solubilizing over the time.

In a pot-type experiment with ryegrass, 32P was used to label isotopically exchangeable soil phosphorus as well as a phosphate fertilizer. The tagging of both forms of phosphorus enable us to determine the pool (L) for soil reserves and the A value which is the availability of these reserves in the presence of fertilizer. The authors establish correlations between the ratio K = L/A and the assimilable phosphorus as determined by the Bray II method, and also between K and the "extra" phosphorus. The authors state that the latter was the difference between the plant phosphorus with and without fertilizer. From this study it is concluded: (1) that the K value seems to be a better criterion than the amount of assimilable phosphorus to estimate the phosphorus fertility of a soil; (2) that the study of the variation of the K value according to the soil types informs us about the reserves behavior and about the way of nutrition for the plant. The calculation of the K value is aimed toward a more adequate fertilization for given types of soil.
