Thanks for all the article quotes. I've never read a study. I believe we will be switching from annuals to perennials for food crop production so the food crops can continue to grow their roots deep enough as to tap into the nutrients deeper in the soil and so we stop erosion of the surface soil and continually depleting surface nutrients we have to continually replace with additional nutrients. Which is over fertilization. The majority reason for run off.
