Managing for Balage  

Two critical factors for making any quality stored forage are crop maturity and moisture. In addition, an effective oxygen barrier is essential for quality balage.

Harvesting in the vegetative stage versus the reproductive stage will produce a much higher quality forage. Harvesting legumes in the vegetative stage provides the opportunity to harvest again in 28 days versus a minimum of 42 days when harvested in the reproductive stage. When the forage has reached full bloom or completely headed, the amount of sugars left in the plant is borderline to provide the energy for proper fermentation. Over-mature forage has a much higher tendency to develop molds.

For balage, the optimum moisture level for harvesting should be 40% to 60% for grasses and legumes at 40% to 55%. Forage that is baled and wrapped too wet has a tendency to develop excessive levels of butyric acid which can prevent the completion of fermentation. On the other side of the coin, balage that is too dry will not ferment properly and palatability will be adversely affected.

The balage film should provide the following: serve as an oxygen barrier, have enough tack to seal the bale, be a blown film to withstand contracting and expanding, and last at least one year. The film should be white in color. Any other color will absorb heat, cause excessive temperature inside the bale and bind the protein to the fiber, reducing the rate of digestion.

Additional Thoughts:

Advantages:

Virtually all forages can be harvested as balage.
Legume or grass legume mixtures are excellent sources for this method.
Allows you to harvest when crop reaches optimal stage of maturity.
Reduces weather risk, easier to attain 50% dry matter balage compared to 18% dry matter conventional bale.
Reduces field leaf loss and provides more available nutrients for feeding.
Provides a consistent forage for the feeding period.
Yields and quality can be increased.

Disadvantages:wpe5.jpg (7700 bytes)

Increased weight of the bales due to moisture content.
Plastic wrapped bales must remain sealed to prevent spoilage.
Feeding in bunks or rings is recommended to reduce waste.
Off farm market is limited.
Transportation cost is increased due to water content.
Additional equipment is required for wrapping and handling.
Plastic must be disposed of.

Bermudagrass -- Cautious Optimism

Bermudagrass is a perennial, warm season grass that is fast growing and aggressive. Once established it crowds out competing weeds and grasses. Bermudagrass covers an area by spreading vegetatively via stolons (above ground stems capable of producing roots) and rhizomes (below ground stems capable of producing roots). It is thought to have originated in southeast Africa and has become the important pasture grass in the south. Reduced cold tolerance is a concern for Central Missouri.

World-wide, Bermudagrass has established its reputation due to a number of attributes:

Drought resistance - Coastal Bermudagrass, an improved variety, produced 1.8 tons of hay per acre when fertilized with 100 pounds of N per acre. This study was conducted during the drought year of 1954 with 12.63 inches of rain.
Soil type - Bermudagrass will grow under a wide range of soil types but is best adapted to well drained soils. While it will grows under a wide range of pH levels, it responds to liming if the pH is less than 5.
Bermudagrass is a warm season plant that produces the bulk of its growth during the warm summer months when temperatures average above 75oF. This compliments the growth and yield distribution of cool season grasses that tend to have low forage production during the summer months.
Quality - Bermudagrass quality is dependent upon fertility, genotype and maturity. Mature, unfertilized common Bermudagrass will test 6-7% crude protein (CP). Improved varieties of Bermudagrass in variety trials in Oklahoma have had CP as high as 13.2% (Table 2).
Versatility - In areas of the south where it is best adapted, Bermudagrass is used for both hay and pasture. During the winter months while Bermudagrass is dormant in these areas, it can be overseeded with annual ryegrass to provide additional grazing through the winter. It is more tolerant of close grazing and heavy stocking rates than many other forage grasses.
Yield - Bermudagrass responds well to nitrogen applications. Variety yield trial data from a test conducted in Oklahoma are given in Table 1.

Bermudagrass varieties can be lumped broadly into the categories of "grazing" and "haying". Grazing varieties such as Greenfield, Quickstand, and World Feeder have a prostrate growth habit and a very dense sod. Hay type varieties such as Hardie, Midland and Tifton 44 are more upright in their growth and have a more open sod.

It is established either by planting live sprigs (stolons and or rhizomes) or planting seed. Most of the improved hybrid varieties are poor seed producers making it necessary to establish them through sprigs.

If establishing Bermudagrass with sprigs, a sprigging rate of 15 to 30 bushels per acre is recommended. If seeded, a rate of 4-8 pounds of pure live seed per acre is suggested. Higher rates of either sprigs or seed will result in faster coverage. Sprigs can be planted into a prepared seedbed or no tilled with mechanical spriggers, which are not very common in Central Missouri. Sprigs may also be planted by hand, or spread by a manure spreader, disk in lightly and then cultipacked.

During establishment, weeds that form a canopy above the developing Bermudagrass will greatly slow its spread. Broadleaf weeds can be controlled chemically or by mowing or grazing during the establishment year. Annual grasses can be a real problem to the establishment of Bermudagrass as there are a limited number of herbicides that can be used to control weedy grass that will not also damage the Bermudagrass.

Over the past few months, Bermudagrass grass has been experiencing a surge of interest in Missouri mainly due to the publicity surrounding the variety World Feeder. Table 1 gives the results of variety trials conducted at Haskell, Oklahoma of six commercially available Bermudagrass varieties including World Feeder.

It should be noted that these yields were taken in area of the country that has a longer growing season and an environment more suited to Bermudagrass growth. In Central Missouri, while it may be possible to obtain four hay harvests of Bermudagrass, three are much more likely.

Bermudagrass does have potential in Central Missouri. However, there are a number of considerations that must be taken into account prior to investing in Bermudagrass.

For Central Missouri, the biggest questions are: persistence and winter-hardiness. Common bermudagrasses are found across the Central Missouri region but forage production is low. Of the improved varieties, mild winters for the past several years have not really tested its winter survival ability. In Lincoln, Missouri, Greenfield, Hardie, Guymon, Tifton 44 and Midland varieties have persisted for five years in demonstration plots with no apparent effects of winter damage.

Given its growing season, Bermudagrass has excellent potential to fill in the forage gap created by cool season grasses during the summer. Learning the characteristics of Bermudagrass, its strengths and weaknesses prior to investing in it are advisable to avoid disappointment.wpe3.jpg (3925 bytes)

Taxation Tidbits

The tax reporting cloud has been removed from Conservation Reserve Program (CRP) payments. On March 3, 2000 the Sixth Circuit Court of Appeals reversed the Wuebker v. Commissioner Tax Court case. The Sixth Court ruled CRP payments are subject to self-employment tax if the CRP land bears a "direct nexus" relationship (connection) to the taxpayer’s trade or business of farming or ranching.

Whether you agree with this ruling or not, the ruling does confirm the time tested axiom that "the substance of a transaction is more important than the form used".

This is an election year and several politicians are entering this CRP taxation arena. U.S. Sen. Sam Brownback has introduced the Conservation Reserve Program Taxation Fairness Act, which (if enacted) would provide that farmers were not, are not, and would not be liable for self-employment tax on CRP payments.

Be careful what you wish for – farm income vs. rental income has some advantages. Remember that tax management is a balancing activity – between income, gift, and estate taxes.
