Effect of Soil Condition Change on Grain Yield Based on Classification and Monitoring of Cultivated Land Resource Quality:A Case Study of Lankao County in Henan
This study utilized trend analysis and comparative analysis methods to analyze the changes of soil conditions over various years at soil monitoring sample points and their subsequent effects on grain yield,using data extracted from the cultivated land resource quality classification monitoring in Lankao County.The findings demonstrated that enhancements in grain yield could be attributed to the increase of soil organic matter content and a reasonable augmentation of soil pH.For the purpose of yield optimization,it was suggested that the utilization of organic fertilizers should be increased on the premise of soil testing and formula fertilization,consequently ameliorating the soil organic matter content.Concurrently,context-specific measures for improving soil pH should be devised,considering the unique characteristics of the local soil and the types of predominant crops.
