Development of Acidification-resistant Organic Fertilizer for Improvement of Acid Red Soil in Guangxi

摘要

The soil in Guangxi has been severely acidified,restricting sustainable development of agriculture.In this paper,based on the screening of organic fertilizer additives,a method for the production of acidification-resistant organic fertilizer specific for acid red soil improvement was proposed,and the developed acidification-resistant organic fertilizer was used in sugarcane experiment.The results showed that in the treatment that the specific acidification-resistant organic fertilizer was applied,the yield of sugarcane significantly increased,the p H value of soil effectively increased,the physical and chemical properties of soil improved,and the contents of microorganisms and available nutrients in soil increased.
