Terms and Definitions This standard does not involve term definitions. 4. Early Warning Value The early warning value of sulfentrazone in soil for healthy wheat growth in the Beijing-Tianjin-Hebei region shall comply with the provisions of Table 1. 5. Monitoring and Evaluation 5.1 Soil Sample Collection Collect the topsoil (0–20 cm) and determine the content of sulfentrazone and soil pH in the soil. The methods for soil sampling point layout, sample collection, transfer, preparation, and storage shall be implemented in accordance with the provisions of NY/T 395. 5.2 Detection Methods Determine the content of sulfentrazone in soil in accordance with the provisions of NY/T 2067. Determine the soil pH in accordance with the provisions of NY/T 1377. When using other equivalent methods for analysis, their accuracy and precision shall not be lower than t
