It looks like you can get more specific information from the local Farm Service Agency. (I did not know that was a thing! Learn something new everyday!)
Besides providing loans to actually buy a farm, WA has the
Debt for Nature Program.
"The Debt for Nature Program, also known as the Debt Cancellation Conservation Contract Program, is available to persons with FSA loans secured by real estate who may qualify for cancellation of a portion of their FSA indebtedness in exchange for a conservation contract with a term of 50, 30, or 10 years. A conservation contract is a voluntary legal agreement that restricts the type and amount of development and farming practices that may take place on portions of a landowner's property. Contracts may be established on marginal cropland and other environmentally sensitive lands for conservation, recreation, and wildlife purposes."
