Scope
Scope: This standard provides the technical implementation process and methods for evaluating the effectiveness of nutrient control technologies in treating cadmium-contaminated paddy fields. This standard is applicable to the evaluation of the effectiveness of nutrient control technologies in treating cadmium-contaminated paddy fields. Main technical content: By conducting coordinated sampling and monitoring of soil and rice, establishing an indicator system for soil environmental quality, fertility, and health, and comprehensively evaluating the effectiveness of nutrient control technologies in treating cadmium-contaminated paddy fields. In this standard, the measurement indicators for soil environmental quality include the cadmium content in the DTPA-extracted form, the measurement indicators for soil fertility quality include organic matter, alkali-soluble nitrogen, effective phosphorus, available potassium, and cation exchange capacity, and the measurement indicators for soil health quality include rice yield and cadmium content in brown rice.
