1. Inquiry of land management department: You can go to the local land management department, such as Land and Resources Bureau and Agriculture Bureau, and ask the staff for information about farmland. Staff can provide relevant cadastral information and planning drawings to help determine the type of farmland.
2. Check the land use planning map: The land use planning map is an important basis for dividing cultivated land types. You can ask for or consult the land use planning map of this area from the relevant departments, which usually indicates the area of basic farmland and general farmland.
3. Consult the township or village: consult the local township government or village committee, who have a more specific understanding of farmland and can provide relevant information.
4. Observe the signs around the farmland: In some areas, signs or signs will be set around the basic farmland, such as the basic farmland protection monument. You can notice whether there is such a sign around the farmland to judge its type.
