Effects of Fertilization on Moisture Content of Soils in the Loess Hilly-gully Region
Objective] The aim of this study was to study the influence of plants on the soil moisture content under different fertilization. [Method] Using sainfoin, sweet clover, Astragalus adsurgens, alfalfa, ryegrass, little flower, white clover as experi-mental material, this study explored the effects of soil moisture on the improvement of soil quality. [Result] Results showed that the soil moisture content of different plants fol ows as: sainfoin > sweet clover > Astragalus adsurgens > alfalfa > peren-nial ryegrass > smal crown > white clover, and the average moisture content reached 24.13% which was 2.45% higher than that of control group. At planting white clover, sweet clover, under the condition of 7 kinds of crops, in the treat-ments without fertilizer and with organic fertilizer, soil moisture content of soil in 0-20 cm grew significantly. [Conclusion] The application of organic fertilizer and grow-ing of plants would improve soil moisture in abandoned fields, enhance the ability of soil water supply, and improve soil fertility.
