Crop modelers wrap up their forecasts of rainfed and irrigated corn yields across the Corn Belt for 2017, noting above-average yields for about 80% of the irrigated sites and more than 60% of the rainfed sites. Irrigated yields ranged from 11%-17% over long-term averages at those sites and rainfed yields at those sites were 13%-40% above average. View data for all the sites.
Nitrogen is a key factor in farm management and economics. One of the most expensive inputs for corn production, it can be easily lost to the environment in multiple forms and directions. One avenue for losing N, as nitrous oxide, has an impact on our climate as a greenhouse gas. Successful strategies for reducing N losses, especially as nitrous oxide, will benefit farmers and the environment.
Figure 1. Some of the six cover crop mixes featured on the Sept. 25 cover crop field day, each planted for a specific purpose. Diversity is important in cover crops to help feed the soil system. (Photo by Paul Jasa) View six cover crop mixes seeded after wheat harvest, each planted for a specific objective, as well as how fertilizer and biomass production varied among the mixes. Includes a no-till drill demonstration.
Figure 1. At the Rob and Trent Bohling Farm near Johnson a cover crop mix of oats, turnips, radishes, and volunteer wheat was planted after wheat and is being compared with an area with no cover crop. The experiment is to evaluate and compare crop yields and soil properties among three systems: cover crops, cover crops followed by grazing, and no cover crop. (Photos by Gary Lesoing) a cover
Figure 1. This new Nebraska Extension circular offers information on distinguishing the major grasses found in Nebraska cropland when they're small and should be managed. (A) Auricles of Canada wildrye clasping the stem, and (B) ligule and auricles of Canada wildrye. A new Nebraska Extension guide shows how to identify and differentiate various grass weeds common to Nebraska agronomic fields.
