| Abstract: | In this paper,the pot experiment was conducted to study the effects of humic acid fertilizer on soil microbial activity and soil available nutrients under the condition of growing forage sorghum in greenhouse.The experiment had three treatments including no fertilizer (CK),chemical fertilizer,and humic acid fertilizer.The results showed that the quantity of soil bacteria in humic acid fertilizer treatment was higher by 45.58% than that in chemical fertilizer treatment at heading stage.In the stages of joint... |
