The uniqueness of alfalfa spring growth has been a core factor for many discussions, research trials, media articles, debates, and flat-out arguments among forage brethren. Generally, the conversation centers around when to cut and the best method to determine forage quality of the maturing alfalfa plant. Spring 2013 may offer additional unique aspects of making […]
One of the most common problems faced by hay or silage producers is how to manage production schedules around unfavorable weather. Inevitably, some wilting forage crops are damaged by rainfall each year, and producers often inquire about the effects of rain damage, and what impact this may have on forage quality, silage fermentation, and animal […]
Research studies in recent years have shown that sulfur (S) may be deficient in some parts of Wisconsin. Sulfur deficiencies are most likely to occur when high S-demanding crops such as alfalfa, canola, or forage brassicas are grown on sandy soils or on other soils that are low in organic matter, far from urbanized areas, or have not received manure within the last 2 years.
The single factor most affecting profitability of alfalfa is yield. This can be seen in the graph at the right which depicts economic data from the Green-Gold program (a third party verified measured yield and quality program) the Wisconsin Forage council used to run.
Most dairy farmers do not have a drive-over scale available on their farms. Frequently it would be useful to know the weight of forage harvested from a field. Measuring alfalfa or corn silage yield is necessary to adjust management practices, to maintain crop inventories, and for crop reporting purposes.
What happens to corn silage yield and quality with later planting dates? The following is a summary of planting date trials conducted at Arlington, WI. The objective of these trials is to measure the impact of planting date on corn forage yield and quality.
Weed suppression can be important during alfalfa establishment as weeds can reduce stand life, alfalfa biomass, and forage quality. To reduce these impacts producers commonly apply herbicides to establishing alfalfa.
Alfalfa stands are typically terminated by herbicides in Wisconsin. While many options are available, combinations of 2,4-D and glyphosate are most commonly used.
Research is developing new understanding of forage, fiber, and the animal’s ability to use them. We have also increased understanding of the genetics of alfalfa to allow improved variety selection methods and enhanced performance for the farmer. This paper will consider both topics. Growing Alfalfa/Grass Mixtures Generally dairymen have perceived grasses to be too high […]
Current recommendations regarding cutting height of alfalfa are designed to maximize yield while maintaining high quality forages and stand longevity. Forage growers frequently cut forages at a height of 3-inches or more. However, recent reports indicate that there may be an advantage to cutting alfalfa closer, leaving an inch or less of stubble height (@griculture […]
Heaving is a problem in some alfalfa stands each year in the Midwest. Heaving occurs on heavy soils that have high moisture contents. Repeated freezing and thawing causes soil expansion and contraction that pushes the tap-rooted plants (and fence posts) out of the soil. The need to push against something is why grasses with fibrous […]
Shorter rotations mean greater profit per acre for the entire farm because of higher alfalfa yield, higher forage quality, reduced pesticide use, greater nitrogen credits, and increased corn yields. Alfalfa is a major profit center on most dairy farms.
