Development of Different Functions of Organic Fertilizers with Chelated Rare Earth and Trace Elements and Their Effects on Rice Development,Yield and Quality
In response to the problems of long-term unreasonable use of large amounts of elemental fertilizers,none-decomposed agricultural waste,etc.,which cause soil compaction,salinization,excessive heavy metal content,and a decrease in agricultural product quality and yield,the organic fertilizers with chelated rare earth and trace elements for improving quality and efficiency,soil improvement,and heavy metal contaminated soil remediation is developed.The production process of organic fertilizers is introduced as well.The results of two consecutive years of field experiments and demonstrations on rice show that three types of organic fertilizers have significant effects on increasing rice yield,improving quality,and saving costs and improving efficiency.The increase in yield ranged from 4.1%to 11.6%,and the beneficial iron and manganese content in the products increased by 2.81%to 87.44%,while the heavy metal content decreased by 4.46%to 61.76%.Three types of organic fertilizers play a certain role in improving the quality of cultivated land and repairing soil barriers.
