What do you mean by abandoned land?

Abandoned wasteland refers to a land use model that is cultivated for several years, abandoned for a long time, and cultivated after soil fertility is restored.

Abandoning soil means that the land has not been reclaimed and cultivated for a long time, or that people have not used and cared for it for a long time.
