We started ridge tilling in the early 80’s as a way to reduce tillage, fuel, fertilizer, and chemicals. We later switched to zone, vertical, and no till in 2013 when ridge till became too labor intensive. Then, we started using more hog manure and chicken litter in 2013. We’ve started to use more cover crops recently and we like to look at fields with residue or cover.
