Please explain this more to me. I'm very interested. Seeing as that is a part of my life .
legumes fix nitrogen (well, the nodules on their roots do)...that is, they take nitrogen that is not fixed...like atmospheric N2 and convert it to something that will stay in the soil, like ammonia....
Start with this...if this is part of your life this page should be all common sense to you...
