There are many benefits when using cover crops in a crop rotation including reduced erosion from wind and water and improved soil organic matter.

It’s imperative that soil be protected and conserved as much as possible because the simple fact is that we no longer have the luxury of leaving our degraded soils in the dust as we go in search of new ground. We must take care of the soil if we have any hope that it will continue to provide for us.

Agricultural producers often base their land management decisions on the living things they can see above the ground – crops, livestock, forage, weeds, insects, wildlife, etc. However, new research is showing they should also consider life found in the soil.

Farmers who have used a three- or four-crop rotation system for more than 10 years are most likely to reap the benefits of improved soil health and higher yields, according to a survey of producers in eastern South Dakota. With fertilizer prices at an all-time high, this might be an opportune time for producers to consider adding oats, peas and spring or winter wheat to their rotations, according to associate professor Tong Wang of South Dakota State University’s Ness School of Management and Economics.

This week’s podcast, sponsored by NewLeaf Symbiotics, features Katja Koehler-Cole, Research Assistant Professor, University of Nebraska. Koehler-Cole will discuss how soil nitrates are lost in corn-soybean rotations, the role of soil microbes in the soil, what cover crops provide soil microbes, and more.

Farm profitability from grain production is an age-old concern of farmers. Improving yield stability is also an important management strategy to counteract weather extremes (i.e., heat waves, droughts, flooding) that stress both crop growth and farm profitability. Farmers need reliable information about the effectiveness of crop rotation and fertilizer management that involves many years of data to account for the year-to-year variability in growing conditions.

So, you added wheat into your rotation to help diversify the market opportunity of your operation. Now that the wheat is off and straw is baled, that field is a clean slate. Read more in this article from Farm & Dairy.

Cover crops—which are typically added to a crop rotation in between two commodity or forage crops—provide living, seasonal soil cover with a variety of on-farm benefits, such as increased soil moisture capacity, improved nutrient cycling, and weed suppression. Cover crops can also provide public benefits by reducing sediment loss, nutrient runoff, and leaching; reducing flooding; and storing carbon in the soil.

This week’s podcast, sponsored by GS3 Quality Seed, features Amanda Kautz, district conservationist with NRCS. Kautz will discuss why silage is a good opportunity for growers to incorporate covers, how growers ensure good cover crop growth for silage, soil health benefits offered by covers after they’ve been harvested as silage, and more.

For corn, using dairy manure and legume cover crops in crop rotations can reduce the need for inorganic nitrogen fertilizer and protect water quality, but these practices also can contribute to emissions of nitrous oxide — a potent greenhouse gas.
