A bright future for grasses
The grazing movement is, both literally and figuratively, a grass-roots movement. Many livestock producers in the northern USA have recently moved from predominantly confinement feeding systems to grazing systems. Most of them use some form of management-intensive rotational grazing in which livestock are periodically rotated from one paddock to another, allowing the plants in each […]
Applying manure to alfalfa
Manure has traditionally been targeted for corn acres during the course of a crop rotation. The reason has simply been that corn uses and needs all of the nutrients supplied by manure (especially nitrogen).
Microbial inoculants for silage
Ensiling is an important means to preserve forage quality. Although silage fermentation occurs naturally under anaerobic conditions due to the native bacteria on plants, the speed and efficiency of the fermentation (pH drop) is variable, depending on the numbers and types of lactic acid bacteria on the crop.
Impact of Defoliation on Corn Forage Quality
An improved understanding of the effects of defoliation on forage yield and quality would improve the ability of agronomists, farmers, and crop insurance adjusters to assess the economic impact of hail damage to corn harvested for forage.
Emergency forage options
The optimum crop to plant for emergency forage should be determined by 1) when and how it will be utilized, 2) the forage quality needed, and 3) seed availability and cost. In 2003 and 2004, emergency forage trials were conducted at 5 locations across Wisconsin, Michigan and Minnesota. Trials were seeded at each of three […]
Understanding NDF Digestibility of Forages
Recently forage-testing laboratories have begun to evaluate forages for neutral detergent fiber (NDF) digestibility. Evaluation of forages for NDF digestibility is being conducted to aid prediction of total forage digestibility. There are several important reasons why forages are being evaluated for NDF digestibility.
Pure live seed
We have paid little attention to Pure Live Seed (PLS) in the Midwest because we have generally had high quality seed (greater than 90% germ and 98% purity). But the short forage seed supply has caused some low quality seed to come on the market.
Use of Brassica Crops in Grazing Systems
Forage Brassicas, such as rape, kale, turnips, and swedes, are high yielding, high quality, fast growing crops. The above ground parts (stems and leaves) of rape and kale and all parts (stems, leaves, and roots) of turnips and swedes are utilized by livestock. Brassicas are high quality forage if harvested before heading. Above ground parts […]
Soybeans for Hay or Silage
Soybeans can be harvested as a hay or silage crop. This option is often considered either when forage is short or when the soybean crop is damaged for harvest as a grain crop (for example. following hail damage or an early frost). Soybean forage, like most legumes, tends to be high in protein and low […]
Sorghums, Sudangrass, and Sorghum-Sudan Hybrids
What are the different types of sorghum and sudangrasses? Sorghum and sudangrasses are warm-weather crops and will perform best in years when the growing season is characterized by higher-than-average temperatures. Cool conditions will severely limit productivity. Sorghums are diverse but generally fall into the following categories: Grain Sorghum – also called milo, used for grain production […]
