Field evaluation of water or citrate soluble phosphorus in modified phosphate rocks for soybean Avaliação agronômica do fósforo solúvel em água ou citrato de fosfatos de rocha acidulados para a soja
Ten P fertilizers were collected (commercial fertilizers) or synthesized (experimental sources) in order to obtain single superphosphates varying in water and citrate solubility. A standard source of P was also produced by crystallization of the water-soluble fraction of a triple superphosphate. Ele...
