I would like to know how to translate "as it applied" in this sentence:
The Soil Conservation Service also became involved with some of the provisions of the Food Security Act of 1985. Under this program, SCS conservationists worked directly with farmers to determine soil erodibility as it applied to the preservation of wetlands. Some of the most erodible land was taken out of production and covered with protective vegetation, and farmers received rental payments in return.
What does it mean? I don't seem to get it.
