Biochar(BC)is widely applied in agricultural production for its multiple uses such as carbon ***,application of BC alone has limited effect on soil fertility and crop yield,especially alkaline ***,a pot experiment on Chinese cabbage(Brassica rapa ***)was carried out in this study to investigate the effect of BC applied with organic fertilizer(OF)on alkaline soil properties and crop *** be specific,BC and OF were respectively applied at 0,1%,2%,and 3%,and Chinese cabbage was transplanted and cultivated for 2.5 *** showed that BC and OF increased the content of both organic matter and available P in alkaline soil(P<0.05).Moreover,the application of OF alone decreased the pH value but raised available N content of alkaline soil,and the application of only BC demonstrated the contrary effect(P<0.05).OF significantly improved crop yield(P<0.05),but the effect of BC was *** yield was the highest under the treatment of 1%BC and 3%***,BC had limited effect on alkaline soil fertility and crop yield,but the application with OF was a good option for ameliorating alkaline soil and raising crop yield.
