| Abstract: | The experiment in effect of dolomite on amelioration of acid red-yellow soil with the third and fourth seasons rape and maize as trial was conducted. The results indicated that the application of dolomite could promote crop growth, improve yield components and raise yield. Rape and maize can obtain the highest yield and the best economic benefit as the amount of dolomite application was 1 600 kg/hm 2.The results also showed that the application of dolomite has notable residual effect. |
