The farmland at home was polluted by chicken manure flowing out of the chicken farm, and the testing department came to test and sample it.

1. There are two kinds of pollution on the farm: air and water. Is there any pollution in the soil? Is organic fertilizer still called polluting farmland? It is not illegal for farmers to apply chicken manure on the land ~ ~

2. It is useless to take surface soil samples, because soil pollution is not detected.

3. The depth is mainly based on the consideration of groundwater pollution, so this kind of detection is normal, and it is useless to claim to detect the soil on the surface of farmland.

FYI
