Packing Bunker and Pile Silos to Minimize Porosity
Attaining a high silage density is important for two primary reasons. Most importantly, density and dry matter content determine the porosity of the silage.
Forage Production and Management
Growing high-quality grass for dairy rations requires attention to detail
As interest grows in adding grasses to dairy rations (to add digestible fiber and improve cow performance and health), many dairy producers find themselves learning about a feedstuff they haven’t grown or used in many years. This Fact Sheet will explore some reasons for feeding grasses, discuss some of the agronomic considerations producers need to think about when growing grasses for […]
Relative Forage Quality
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.
Managing hail-damaged alfalfa and red clover
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 […]
Alfalfa removal in the spring
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.
Yield and management of Roundup-Ready alfalfa
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.
Estimating Alfalfa RFV in the Field Using PEAQ
Step 1: Choose a representative 2-square-foot area in the field. Step 2: Determine the most mature stem in the 2-square-foot sampling area using the criteria shown in the table to the right. Step 3: Measure the length of the tallest stem in the 2-square-foot area. Measure if from the soil surface (next to plant crown) to the […]
Effect of seedling year stress on future alfalfa yields
Stress in the seeding year reduces future yields of alfalfa. This occurs because the seeding year determines the stand plant density as well as individual plant size and vigor. The following paragraphs will show that autotoxicity, potato leaf hopper, cover crop, and, possibly, drought stresses in the seeding year will reduce alfalfa yield in future years, even when the stress is gone.
Diagnosing and managing winter aflafa injury
Winter Injury occurs someplace in Wisconsin every year. Being able to diagnose and manage winter damaged stands may help prolong stand life and increase production. Below is a brief discussion on diagnosing and managing winter damaged alfalfa.
Drive-over silage pile construction
Properly constructed, a drive-over silage pile can provide efficient and economical silage storage. Proper design, filling, covering and feed-out is critical for optimizing silage dry matter recovery from a drive-over pile.
Ryegrass Types for Pasture and Hay
Increased awareness of ryegrass as a potential forage has occurred in the upper Midwest. Ryegrasses are excellent, high quality forage, establishing rapidly and producing good yield in the seeding year if cool (50 to 75°F) exist and adequate moist is available. Ryegrasses have low tolerance for water stress. Several ryegrass types exist and species within […]
Frost Seeding Legumes and Grasses into Established Pastures
Frost seeding legumes and grasses is common means to improve forage yield or change the species composition of a pasture. Frost seeding offers several potential advantages: the ability to establish forage in an undisturbed sod, a reduced need for labor and energy compared to conventional seeding methods, the ability to establish forages with minimum equipment investment, a shortened “non-grazing” period, and a means to maintain stands at productive levels with both grasses and legumes.
