Phosphate fertilizer improves plant nutrition and soybean yield on the Amazon agricultural frontier

The utilization of phosphate fertilizers for soybean growing on amazon soils is a challenge. Some soils are very clayed, which means they can easily fix phosphorus (P) from fertilizers. However, soybeans are very responsible to P since this nutrient has a direct relationship with nitrogen biological...

Some soils are very clayed, which means they can easily fix phosphorus (P) from fertilizers. However, soybeans are very responsible to P since this nutrient has a direct relationship with nitrogen biological fixation and grain production. To understand the effect of P on plant nutrition and development, an experiment with soybeans was carried out in field conditions to evaluate the nutrient concentration in diagnostic leaves, P availability in soil, and grain yield of soybeans cultivated in a very clayey Oxisol. The objective was to evaluate the effect of phosphate fertilizer on the availability of P in the soil, as well as the concentration of N, P, and S in the diagnostic leaves, suggesting a proper rate of P2O5 for the first soybean crop in an area of abandoned pasture in the eastern Amazon. The phosphate fertilization increased the availability of soil P and the concentrations of P, N, and S in the diagnostic leaves. The concentrations of P and S in the leaves were highly correlated with N concentration. The rates of P increased the grain yield, dry mass of one thousand grains, number of pods per plant, and plant height, attributes that were highly correlated with the concentration of P, S, and N in the leaves. We recommend the rate of P2O5 at 120 kg ha–1 for the first soybean cultivation in an abandoned pasture located in eastern Amazon.Possidônio Guimarães RodriguesJoão Cardoso de Souza JuniorAline Cristina RichartLeila Sobral SampaioAna Regina da Rocha AraujoMário Lopes da Silva JuniorUniversidade Federal Rural da Amazônia (UFRA)articlebiological nitrogen fixationglycine maxgrain yieldoxisolsoil phosporusAgricultureSAgriculture (General)S1-972Environmental sciencesGE1-350PTRevista de Ciências Agrárias, Vol 64 (2021)
