The benefits of using legumes in crop rotations is well established. This study explored a cover crop system utilizing annual clovers in Wisconsin that takes advantage of shorter season crops (i.e. winter wheat, vegetable crops), to enhance rotational impacts, to provide nitrogen credits to the next year’s crop, and to grow additional biomass that potentially […]
Relative Feed Value has been widely used for ranking forage for sale, inventorying and allocating forage lots to animal groups according to their quality needs, as well as determining when to harvest.
For determination of keeping stand of new seedlings: Determine whether the seedlings have developed crowns (pull a plant and feel if ridge between root and top growth which usually develops when plant is 3 to 4 inches tall). All seedlings without crowns and with damaged terminal buds will die. Count remaining plants and keep stand […]
Cover crop species recommendations change depending on whether you are in Northern or Southern Wisconsin. Northern Wisconsin Cover Crop Options Small grains / grasses Cereal rye is the only option for seeding cover crops after corn for grain in Northern WI but it should be planted by late October. Much later than this and rye […]
Cover crop species recommendations change depending on where you are. The map below is divided between Northern and Southern Wisconsin – click one of the maps below to view the recommendations for that area. Northern Wisconsin Cover Crop Options Small grains / grasses Cereal rye is the most reliable option for seeding grass cover crops […]
One of the most important times to use cover crops is after corn harvested as silage leaving very little residue and the soil vulnerable to erosion in the winter and subsequent spring. There are many ways to plant cover crops, please go to this page to look at planting recommendations. Cover crop species recommendations change depending […]
Wisconsin’s short growing season doesn’t provide a lot of time for growing cover crops. However, the early harvest of winter wheat allows an excellent window for cover crops to grow, protect the soil and provide other benefits. Cover crop recommendations typically change depending on where you are in Wisconsin but because of the early harvest […]
While removal of old stands is recommended with fall applications, many fields are now slated for removal due to winter-kill. This can be challenging, but options exist depending on the situation. Below I discuss management options for common scenarios this spring.
Establishment of dense vigorous stands of alfalfa is essential for long-term profitability, but establishment can be challenging because seedling alfalfa is vulnerable to competition from annual weeds and wind and water erosion. Roundup Ready Alfalfa was re-introduced last year as a new tool available to farmers growing high-quality alfalfa. While not for everyone, it will be useful for many alfalfa growers.
UW-Madison Extension experts discuss selecting cover crops and questions that you should be to ask yourself to help clarify your goals for using cover crops.
Cover crops can provide many benefits for the soil in crop productions systems. Benefits can include conserving soil and water as well as improving the soil. Reduced Erosion An obvious effect of growing cover crops is covering the soil surface, which can significantly reduce the potential for wind and water erosion. This is particularly true […]
Interseeding (Drilling or broadcasting early season into standing crop) Establishing cover crops after corn and soybeans is a challenge in Wisconsin due to the minimal amount of growing season left after harvest. Interseeding a cover crop during the vegetative growth of these crops provides Wisconsin farmers a cover crop establishment method earlier in the season. […]
