Nebraska’s last winter storm blanketed much of the state in significant snowfall, leaving behind 15 inches in the west central region to nearly two feet in central Nebraska. While this is great news for our drought conditions, it’s important to remember that, on average, it takes 10 inches of snow to get one inch of water. Additionally, snow cover has other benefits beyond adding moisture, as well as increasing considerations when winter grazing.
Snow cover in crop fields, particularly in early winter, acts as an insulator for the soil, trapping heat and restricting the depth of the frost layer. This insulation effect also allows the soil to thaw quicker in the spring. In addition to replenishing soil moisture, snow cover helps to preserve existing moisture while also protecting against wind and water erosion. While we can’t control the timing and amount of snow we receive, producers can encourage snow cover by maintaining standing residue in fields over the winter.
For winter grazing, it’s important to remember that while cattle can graze through snow and ice, the height and structure of forage as well as the type of precipitation will determine ease of grazing. Heavy, wet snow or snow that has formed a surface crust will cause animals to work harder to eat. In these situations, it’s recommended that producers keep an eye on animal condition and be prepared to supplement when necessary. — Samantha Daniel, Nebraska Extension educator
