Drought Stress Reduces Corn Silage Yield More Than Quality
Farmers trying to decide about using drought affected corn fields must first determine success of pollination. If pollination will affect grain yield, then growers must follow directions given by hail adjusters to ensure insurance payment. If the decision is made to harvest the field for silage, then it must be cut at the proper moisture; the crop is usually wetter than it appears.
Cut, bale, SCOUT!
Weekly Scouting – 20 sweeps at 5 locations in each alfalfa field. Because leafhopper population densities vary from year to year and from field to field, the only way to accurately determine damage potential is by monitoring fields on a weekly schedule.
FAQs about liming in Wisconsin
Beginning in 2007, Wisconsin has a new lime recommendation program. Will this increase or decrease the lime rates that are being recommended? Neither. In some cases the recommendations may be a bit lower and in some cases higher, but the new system will more accurately assess the level of acidity in the soil and lead […]
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.
