Abstract: The natural meadow is facing with various degradations in Horqin. In order to attain better results of soil improvement, the effect of compound bio-fertilizers on soil physical and chemical properties was investigated. The Humic acid, molasses fermentation and alginic acid were selected and the effect of comprehensive the above three compound bio-fertilizers was measured, so there were 5 treatments in this study in addition control, marking CK, F,T, H and A respectively. The results showed that the compound bio-fertilizers increased soil water content and decreased soil bulk density. The soil organism matter was also increased and T,H and A were significantly higher than CK.A was higher than CK by 22.8%. So the compound bio-fertilizers accelerated soil physical condition and nutrient balance.
