I would put up an electric fence around the soybeans and/or broadcast wheat or something green that will grow just as leaves are starting to fall.You can also check around to see what switch will grow in that area just remember you will want to burn it so maybe plan firebreak from clover or something.You could do fruit trees with clover in that small plot but fruit trees aren't usually late enough to produce through season.Pears are alot easier if you can find one for that zone
