Effect of different nitrogen fertilizers on transformation of synthesized phosphates in calcareous Chao soils

Effect of different nitrogen fertilizers on transformation of synthesized phosphates in calcareous Chao soils

Acta Pedologica Sinica 40(2): 252-260

Pot trials were conducted to study the effects of NH4+-N, CO(NH2)2 and NO3--N on the transformation of several synthesized phosphates in light clay calcareous Chao soil. The results indicated that treatment with maize and no added P decreased to different degree the content of all inorganic P species in rhizosphere. DCP, OCP, Al-P applied mostly transformed into other inorganic phosphates other than dicalcium phosphate, octacalcium phosphate, aluminium phosphate, respectively.
