Abstract:

In this study, a two-year pot experiment with a peanut (Arachis hypogaea L.) and radish (Raphanus sativus L.) rotation system was conducted to investigate changes in soil chemical properties and microbial characteristics and to determine the internal relationship of these variables after pig manure application. The selected soil types include Agri-Udic Ferrosols, Ali-Udic Argosols and Ali-Udic Cambisols, which are widely distributed throughout subtropical China. The annual pig manure application amounts were 25, 50, 100, 200, 400 and 800 kg P ha-1 . The results of our experiments showed that the soil pH (R 2 =0.57_0.87, PPPPPP
