Effect of Fertilization on the Maturation of Red Soil Parent Material

Red soil is widely distributed in China, with strong acidity and low nutrient content. It needs to be fertilized and improved when planting crops. The effects of Fertilization on the parent material, phosphorus and sulfur elements in red soil were discussed. Six groups of control experiments were set up, in which different fertilizer combinations were used as the base fertilizer of red soil. The organic matter, phosphorus, pH value and crop growth in red soil were observed by planting wheat and corn. The results showed that the mixed application of chemical fertilizer and organic fertilizer could maintain the fertility of red soil and acid and alkali. The control effect of degree is the best. Therefore, in the process of red soil improvement, we should pay attention to the application of organic fertilizer.
