Great program, worth listening to.  Hopefully the transcript will be put up soon.  I think we do need to consider better Nitrogen capture.  Undoubtedly tilling bio matter into the soil will also help improve the soil beyond just adding Nitrogen.

I thought a little about the wheat production in Eastern Washington when listening to the program.  Moisture is a problem.  I'm not sure exactly what they do, but I think they grow wheat one year.  Then leave the fallow one year in which the soil is supposed to soak up some moisture, and then grow a wheat crop again the third year.  I think the program mentioned a legume that took about 2 years to mature.  It would seem as if there would be a lot of time growing secondary crops. 

Last year I did an experiment planting peas and corn in the same row.  I should probably try the experiment again, but it seemed as if neither the peas, nor the corn grew well.  So co-planting peas and corn didn't work well. 

Thus, I presume the legumes would have to be part of a crop rotation.
