By grazing cover crops, farmers are adding to the established benefit of improved soil quality and other factors, says Denise Schwab, Iowa State University Extension beef specialist based in eastern Iowa. Prior to grazing in the fall, Schwab says to use the “pluck test” to check on root vigor.

Frost, hail and disease can cause nitrates to accumulate due to reduced leaf area, which limits the rate of photosynthesis. The risk of nitrate toxicity also increases when high levels of nitrogen fertilizer have been applied.

Winter grazing is a useful option for farmers who also raise livestock. They can feed them using cover crops they were going to plant anyway, a cost-efficient and sustainable practice. But how does winter grazing impact the soil underneath? Hayley Crowell, researcher at Auburn University, and her team worked to find out.

Daryl Obermeyer had already implemented cover cropping practices in his operation before the NRCS and On-Farm Research study started. He used this study to validate what he was doing and get concrete data and results of what was really happening.

Transitioning to organic, Noah Wendt and Caleb Akin are closely planning for success in three areas: nutrients for the following crop, weed control and grazing opportunities. In this article, from the Practical Farmers of Iowa, Noah and Caleb talk specifically about summer covers and a few new practices they're testing on their farm.

As feed costs move higher, cattle producers continue to look at alternative options that can keep cows and calves maintaining or gaining weight. Many have turned to cover crops.

Andrew Rees started to question the grassland management at Moor Farm, Haverfordwest, where he farms with his wife, Vicky, and mother, Jean, three years ago. Since then, he has cut nitrogen use by more than 60% and planted herbal leys or cover crops across a fifth of the farm.

Researchers went out about 2-3 weeks after farmers started grazing a cover crop field to measure standing and post-grazing cover crop biomass, and soil health before, the day after, and 2-3 weeks after grazing. One big factor determining profit was the number of times the cover crop could be grazed, and the quantity of grazed biomass consumed.
