For over 50 years farmers have been encouraged to practice conservation tillage. That meant plowing along the contour of the land, installing grassed waterways, planting cover crops to protect the soil during winter or installing windbreaks with tree plantings. These methods were intended to slow down water erosion and to leave crop stubble intact to protect the soil from wind erosion. In many agricultural areas, soil loss from wind erosion amounts to several tons per acre per year.
Since we’ve had little snow cover and high winds some farmers will be left with a little less top soil come Spring. The soil left behind from the black drifts in the ditches will follow the drainage path to the rivers, streams and eventually the lake. Plus, any nutrients,contaminets and pathogens from crop residue or the liquid manure applied to the fields before winter will be carried with the wind blown soil and runoff.
Drive along any roadway in Kewaunee County right now and you’ll see what’s shown in these submitted photos.
