Kinetics of Phosphorus Release in Soils with Different Textures in Intensive Cultivation Systems

Fatemeh Ahmadi

In this study, the effect of loam and Sandy loam textures on Phosphorus (P) release was investigated in greenhouse intensive cultivation soils of Kurdistan, Western Iran. Results showed that the kinetic of P release was higher in soils with sandy loam texture than loam texture soils. It probably was due to low positive charge points and adsorption capacity of sandy loam soils in compare with loam soils. So, more attentions must be conducted in sandy loam textures in cultivation systems because of environmental problems. As well as, according to our results other soil properties like organic matter (OM) and Cation exchange capacity (CEC) showed high correlation in respect to P release.
