Nebraska farmer Bill Volkmer describes himself as an “old farmer.” But this old farmer is willing to learn some new tricks. He started planting cover crops in 2011. Cover-cropping — the practice of keeping fields covered between cash-crops — leads to a healthier, more bio-diverse soil and better crop productivity, which directly helps the bottom line. By selecting specific plants, from amongst the broadleafs, the grasses and the legumes, producers can improve their soils. By keeping soil covered, there’s less evaporation, and when it’s windy, there’s less loss of topsoil.
