Initial research report on soil fertility improvement by planting Medicago sativa
HU Fa-cheng (Wuwei Technical Service Center of Animal Husbandry and Veterinary Medicine, Wuwei 733000, China)
The experiment result shows that planting alfalfa has improved soil physical property; and soil volume weight has dropped. Soil porosity enhanced, soil pellet texture tended being more rational. Improvement of the permeability of soil moisture and aeration of soil enhanced the conservation function of soil fertility and moisture. Soil nutrient has changed. Total nitrogen and organic matter contents have increased, quick potassium content has reduced; total phosphorous has been small. In practice, it needs to pay attention to phosphate fertilizer and potassium fertilizer, so as to increase grass yield.
