2024-10-29 Soil Quality Evaluation Dataset of Northeast Corn Belt (2013) doi:10.57760/sciencedb.iga.00955 en a. Data content (data file/table name, including observation indicators) This data includes the Northeast Corn Belt cultivated land soil quality evaluation dataset (full dataset TDS and minimum dataset MDS), reflecting the characteristic indicators of soil quality, environmental factors, agricultural management, and the relationship between soil quality, providing data support for farmland protection, soil remediation, and other aspects. b. Construction purpose Soil quality assessment has become a fundamental work for sustainable agricultural development. Understanding the soil quality of cultivated land in the Northeast corn belt and improving agricultural efficiency can provide valuable foundations for alleviating the supply and marketing contradictions in China's corn production. At the same time, research is also of great significance for ensuring national food security and promoting the development of animal husbandry and corn processing industry. c. Service target It can widely serve scientific researchers in related disciplines such as farmland protection and soil quality assessment. d. Time range of data 2013 e.
