Monitoring and Evaluation of Supplementary Cultivated Land Quality in Pilot Counties in Anhui
Taking Quanjiao County,Changfeng County and Wuhe County in Anhui Province as the research objects,the soil fertility and health status of supplementary cultivated land were monitored,and the conformity of cultivated land quality grade with basic conditions of agricultural production was investigated and evaluated.The results showed that the average quality grade of supplemented cultivated land in Quanjiao County,Changfeng County and Wuhe County in 2020 was 5.198,4.811 and 3.911 respectively.In pilot counties,the average quality grade of supplemented cultivated land was generally lower than the average of all cultivated land.The dis-tribution of supplemented cultivated land quality grade area was more dispersed than that of all cultivated land quality grade area.The quality grade of supplementary cultivated land was positively correlated with that of all cultivated land,and negatively correlated with the area of supplementary cultivated land.The average of available potassium and pH value in soil of supplemented cultivated land was higher than the average of all culti-vated land,the average of available phosphorus was lower than the average of all cultivated land,and the average of organic matter was significantly different from the average of all cultivated land.
