Using cover crops is not a short-term investment. In fact, it’s the complete opposite. Cover crops are an investment in the long-term soil health and a conscious decision to focus more on stewardship of the land rather than short-term profits.
As with all things related to cover crops, growers have a bevy of options to choose from, including termination methods. According to the results of the first-ever Cover Crop Benchmark Study conducted by Cover Crop Strategies, herbicides were the termination method of choice for a whopping 69% of growers in 2019.
Farmers aren't immune to changing weather patterns affecting the Midwest. That's why those who are adopting conservation practices hope other farmers follow suit. Read more in this article from Public News Service.
Soybean planting is well ahead of the five-year average through mid-May and provides an opportunity to consider cover crops. John Pike, agronomic consultant and researcher at Pike Ag, Marion, spoke of developing a system to successfully manage soybeans and cover crops in a breakout sessions at the Illinois Soybean Association’s Soybean Summit.

Crop roller “crimping” has become a common way to mechanically terminate cover crops. Crimpers are used to kill grass cover crops (cereal rye, barley, wheat, sorghum, Sudan, pearl millet), vetches (hairy and common), annual clovers (crimson and balansa), buckwheat, and multi-species cover crops.

Cover crops can be immediately planted following grain crop harvest, or during fallow in a rotation, which provides extra forage in the fall that can be harvested or grazed. Many producers are already inserting full season cover crops for grazing into their cropping rotation.
While cover crops are not a new concept for farmers, Erika Lundy said she has been impressed with the amount of adaptation and implementation she has seen over the past few years. Lundy, a beef specialist with Iowa State University Extension, said one of the major benefits of cover crops is providing high-quality forage for cattle with high protein and energy levels.

The Haney soil health test, named for USDA scientist Rick Haney, includes more than a dozen different soil test values. These include standard macro- and micro-nutrients for plant consumption, but what’s different about the Haney test is that it also estimates nutrients for microbial consumption, focusing on how much carbon (C ) and nitrogen (N) is in the soil.

Major farm and livestock groups held a press conference in February to project a united voice on an issue they’ve long avoided. The coalition leaders said they wanted to join the fight against climate change rather than remain cast as villains avoiding the responsibility. Read more in this article from Roll Call.
Those who did have the chance to burn down cover crops may notice the dead residue insulating the soil. This is excellent for soil conservation, traps excess moisture and slows evaporation, so soil takes longer to dry enough to be suitable for corn and soybean planting.
