| Abstract: | The effect of large dosage of phosphate fertilizer on Mn,Cu and Fe nutrition on prin-Ciple agricultural soils in Gansu were studied by pot experiment.The results were as followe:(1)theapplication of p could increase significantly the content of loose bound to organic matter form Mn,fixed bound to organic matter form Mn and loose bound to organic matter form Fe, but decrease the content of carbonate bound form Mn, Cu and Fe;(2)the application of Mn and Cu could increase sig nificantly the content of loose bound to organic matter form Cu and carbonate bound form Cu;(3)the application of P could decrease the content of Cu and corn seedling. |
