Acidic Soil Remediation

The acidification of cultivated land in China is a growing problem, particularly prominent in the main cash crop and grain-producing areas of Southern China (e.g., Hunan, Jiangxi, Fujian, Guangdong) and certain horticultural zones (such as orchards and tea plantations). Acidification directly inhibits soil biological activity and interferes with the transformation of nutrient forms. It also reduces the availability of essential elements like phosphorus, potassium, and calcium. Simultaneously, the acidic environment promotes the release of metal ions such as manganese (Mn) and aluminum (Al) through dissolution, exerting toxic effects on crops. Ultimately, this severely limits the productive capacity of cultivated land and the sustainable development of agriculture.

Service Targets

Agricultural and Rural Authorities / Competent Departments

Service Contents

1.  Implementation Technical Services for Acidified Cultivated Land Remediation: Tailor improvement plans based on specific acidification characteristics. Implement soil improvement measures including enhancing the plow layer fertility and applying soil conditioning materials.

2.  Effectiveness Monitoring and Evaluation Services: Conduct supervisory sampling and testing of soil and applied materials before and after the implementation of acidified land remediation. Following project implementation, perform professional evaluations of indicators such as cultivated land soil pH, cultivated land quality grade, and grain production capacity.
