Nutrient runoff from agricultural production is a significant source of water pollution in the U.S., and climate change that produces extreme weather events is likely to exacerbate the problem. A new study from the University of Illinois Urbana-Champaign looks at how extreme rainfall impacts runoff and suggests possible mitigation strategies.
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.
If you’re running a farm yourself or managing someone else’s operation, yes, you’re a farmer, but you’re also a businessperson. After all, whether it’s a smaller, family-owned venture or a larger, corporate enterprise, the end game is some form of profitability.
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.
On this episode of Conservation Ag Update, brought to you by Montag, we’re on the road at the National Farm Machinery Show in Louisville, Ky. Jeff Hadacheck from Wisconsin-Madison discusses the long term economic benefits of integrating winter wheat in your corn-soybean rotation. Plus, we visit with Brandon Somers at the Beck’s Practical Farm Research (PFR) insights meeting. Somers talks about his ideal no-till planter.
Needham Ag understands the role of technology in making better use of limited resources within a specific environment by drawing on a wealth of global experience to overcome the challenges facing today's farmers, manufacturers and dealers.
