my name is ross nelson. this is nelson's organic dairy in southeast minnesota. this is my family farm. i farm here with my folks laverne and arlene. >> we have 365 acres. we milk around 80, 85 cows. >> growing up, it was hard. farming was kind of tough because we were conventional. there were fluctuating prices on a day-to-day basis. and then organic came along, and they find a price that seems to work for everyone, and it stays there. we're part of organic valley, which is one of the largest organic co-ops in the nation. >> because we're set up organic, we try to be as sustainable as we can. >> the cattle have to be fed certified organic feed with no gmos, no hormones, no antibiotics, no pesticide, herbicide, or insecticide. 30% of all that they eat in a day has to come from grazing. >> this is where they pretty mh stay all summer, in pasture land, and then we'll be working them back up, plowing it up, putting in corn one year, and then we'll put it right back into pasture again. what's good for the soil is good for us. in the convential side of it, everne's so
