University of Illinois researcher Scott Foxhoven will share new research on replicated trials comparing banded potassium and nitrogen to broadcast application, along with seeding population and yield response experiments at the 2020 National Strip-Tillage Conference.
In a new study from the University of Illinois, scientists document waterhemp’s resistance to yet another class of herbicides, known as Group 15s. The study provides the first documentation of a non-grass plant to be resistant to Group 15 herbicides.
If soils are too acidic, phosphorus reacts with iron and aluminum, making it unavailable to plants. But if soils are too alkaline, phosphorus reacts with calcium and also becomes inaccessible. However, liming can influence other ways by which phosphorus might become available to plants.
Corn and soybean take up relatively large amounts of phosphorus (P) and potassium (K), and much of this P and K ends up in the grain that is taken off the field during harvest. In order to keep soil nutrient levels from dropping over time, the amounts removed need to be replaced by applying fertilizer or manure. In order to know how much nutrient a crop removes, we need to know how much there is in a bushel of harvested grain.
Returning from this year’s National Strip-Tillage Conference (NSTC) in Omaha, Neb., I always appreciate the new connections made at each event, and especially with those attendees who are new to strip-till.
Using high-powered DNA-based tools, a recent study at the University of Illinois identified soil microbes that negatively affect ragweed and provided a new understanding of the complex relationships going on beneath the soil surface between plants and microorganisms.
California farmer Tom Barcellos discusses the challenges of strip-tilling in his unusual environment and how his Bigham strip-till bar and the Orthman 1tripr are able to overcome these hurdles. He'll detail his equipment setup as well as describe how extensive use of RTK GPS to ensure everything lines up with the strip.
Kuhn Krause's focus, above all, is to continue to produce quality products to serve producers better; to strive to respond to their needs with new tools and new technology to meet their growing challenges. Agronomic practices are constantly changing, and at a faster pace now than ever.
