Scope

Main technical content: 6.3.2 Requirements for sampling points: Within the scope of the soil survey of contaminated cultivated land, conduct preliminary and detailed investigations of cultivated land soils. 6.3.2.1 Preliminary investigation: Collect soil samples in 100 m × 100 m grid units. Based on the results of the preliminary investigation, identify areas with high pollutant content as key areas, and conduct detailed investigations and collect soil samples in 50 m × 50 m grid units. Each sampling point shall consist of at least 5 points (inclusive) of equal-weighted mixed samples. For agricultural land surveys, generally collect surface soil samples from 0 cm to 30 cm of the cultivated layer. When deep tillage techniques are involved, profile samples may be collected in some areas as needed. 6.3.2.2 For agricultural product surveys, collect samples of the main agricultural products grown in the area (such as rice, wheat, corn, rapeseed, and vegetables), and simultaneously collect samples of the edible parts of the mature agricultural products at the soil sampling points. The sampling process shall be carried out in accordance with the provisions of NY/T 398.
