Effect of Combined K-Zn-Mn Fertilizer on the Efficiency Nutrient in Soil

Zhang Min-rong

Abstract

According to this experiment,suitable combined K-Zn-Mn can increase the efficiency nutrient content in soil.The effect of K fertilizer on K content in soil is primary.Primely,the K content in soil is increasing according to the increase of K fertilizer,then it is decreasing according to the increase of K fertilizer.The effect of Mn fertilizer on Mn content in soil is primary.The content of Zinc in soil is increasing with the increasing of Zinc fertilizer and manganese fertilizer,and it is decreasing with K fertilizer.
