摘要：Compost made from cattle manure and used as amendment in a field experience on Haplic Chernozems is considered to fulfill all the conditions necessary for application to any type of soil. There were studied the changes of chemical characteristics of soil under the influence of organic fertilization with or without mineral fertilization. Organic fertilization resulted in significant decreases in soil reaction but mineral fertilization produced no significant changes. There has also been significant increases in organic carbon content in variants fertilised with composted manure, but mineral fertilization as well as in pH values, did not lead to significant changes. In terms of total nitrogen content were observed distinct significant changes after the application of compost and significant after mineral fertilization. The combination of the two fertilization systems has led to distinct increases achieving significant total nitrogen content. Ratio C/N declines distinct significantly through organic fertilization. The level of available phosphorus and potassium have been distinct significant increases both in each of the two types of fertilization.. The data obtained from the determination of the macroelements in soil samples suggest that composted cattle manure can be considered an important source of nitrogen, phosphorus and potassium
