I'm going some volunteer research for One Acre Fund and this popped up. Interesting!

If I could tell you the number of times random people have mentioned rotating maize with legumes to fix nitrogen in the soil ... ugh.

Are you quite sure that legumes don't fix nitrogen? Your Grandfather was a very scientific farmer, and he taught me that alfalfa does fix nitrogen in the soil.
