Bill Brush: Effects of Irrigation Water on Soil Fertility MP3
Bill Brush, consultant from California, works with crops and soils and found that the water supply can contaminate and halt any sustainable efforts a farmer makes in his field. In this talk from the 2006 Acres U.S.A. conference, he relays the information he has discovered from his extensive work in the field, and has worked closely with Acres U.S.A. author Neal Kinsey.
