USDA Announces Hay Quality Designations for Nationwide Market News Reporting
USDA Agricultural Marketing Service has adopted hay quality designations for use in the nationwide Market News reporting program. These revised guidelines issued November 1998 establish specific objective measurements of value attributes for each quality category of alfalfa and grass hay.
Nationwide uniformity of price information is the goal of establishing these new quality designations. It is important for hay buyers in California reading Market News price reports about alfalfa in Kansas to know what the quality is of the hay described in that report issued half a continent away.
Market News reporters from five states formed the task force that collected information and input from hay and forage industry representatives that went into the revised quality designation descriptions. USDA and State Department of Agriculture MARKET NEWS reporters are now using the revised guidelines in market reporting across the country.
Following are the revised national hay test guidelines on Alfalfa, Alfalfa/Mix Hay, and Grass Hay. Reporters use the test measurement most prominent in their trade area, along with visual characteristics to determine hay quality.

Hay Quality Designation’s physical descriptions:
Supreme: Very early maturity, pre-bloom, soft fine stemmed, extra leafy. Factors indicative of very high nutritive content. Hay is excellent color and free of damage.
Premium: Early maturity, i.e., pre-bloom in legumes and pre-head in grass hays, extra leafy and fine stemmed-factors indicative of a high nutritive content. Hay is green and free of damage.
Good: Early to average maturity, i.e., early to mid-bloom in legumes and early head in grass hays, leafy, fine to medium stemmed, free of damage other than slight discoloration.
Fair: Late maturity, i.e., mid to late-bloom in legumes, head-in grass hays, moderate or below leaf content, and generally coarse stemmed. Hay may show light damage.
Utility: Hay in very late maturity, such as mature seed pods in legumes or mature head in grass hays, coarse stemmed. This category could include hay discounted due to excessive damage and heavy weed content or mold. Defects will be identified in market reports when using this category.
Forage Quality: The Importance of Testing
Testing forage accurately can provide a good estimation of forage quality. Test results can be used for: marketing and pricing forages; evaluating, growing, cutting, and storage; formulating nutritionally balanced rations; and developing and allocating forage inventories.
Recommended tests for determining forage quality include:
1. Dry Matter (DM)
2. Crude Protein (CP)
3. Acid Detergent Fiber (ADF)
4. Neutral Detergent Fiber (NDF)
5. Calcium (Ca)
6. Phosphorus (P)
Feed values (Total Digestable Nutrients-TDN, Relative Feed Value-RFV, and Relative Forage Quality-RFQ) can be calculated from these core analyses.
Listed below are certified Kansas laboratories which conduct hay and other forage analyses. No endorsement is implied, nor discrimination intended. Individuals should contact the laboratory for a listing of analysis offered, a fee schedule, and specific instructions for sampling and handling. In general, samples should be submitted to the laboratory in the following manner:
Sample
at random
--It is important to select bales at random from throughout the hay
"lot". A lot is defined as forage taken from the same farm, field,
and cut under uniform conditions within a 48-hour time period. A lot can represent
several truck or wagon loads, but all the forage should have been harvested
and stored under identical conditions. For accurate test results, hay or silage
should be stored by lots, and separate samples taken from each lot. Any special
conditions that result in quality differences in a lot, such as rain damage
during harvest or excessive weed populations, should be noted to allow later
assessment of the reasons for quality variations. Avoiding
some bales and choosing others based on appearance will bias the sample. For
stacked hay, samples should be taken from bales at various heights in the stack.
Take
enough core subsamples
--Taking at least 20 core samples from a hay lot minimizes
sample variation.
Use
the proper technique
--For rectangular bales of all sizes, insert the hay probe
12 to 18 inches deep at a right angle into the center of the ends of bales.
For round bales, the probe should be inserted at right angles to the outside
circumference of the bales.
Handle
samples correctly
--Combine core samples from a given lot into a single sample
and store in a sealed plastic freezer bag. Samples should be protected from
heat or direct sun, and promptly sent to a laboratory for analyses. The sample
should weigh approximately 1/2 to 3/4 pound. With larger samples, many labs
will not grind the entire sample. Too small a sample will not adequately represent
the hay lot.
Split
samples correctly
--To test the performance of a particular laboratory (or the sampling technique), a fully ground and thoroughly mixed sample should be split and submitted. Unground samples should not be split.

Certified Weed-Free Forage and Mulch Program
In 1996, the North American Weed Management Association (NAWMA) brought together representatives from federal land management agencies, state agencies, counties and forage producer to develop a uniform standard for certifying forage and mulch free of noxious weed seeds. The standards are designed to:
Assure all participants that forage and mulch certified through this program meet a minimum acceptable standard;
Provide consistency between states;
Limit the spread of noxious weeds.
Weed-free forage is required on many U.S. Forest Service and Bureau of Land Management lands, in national parks, military locations, tribal lands, and National Fish and Wildlife refuges. Certifiable forage products include straw, alfalfa hay, grass hay, grain hay, and forage pellets and cubes. Recreational horse riders using federal property may need weed-free forage to feed their horses, and state and federal agencies may require weed-free mulch for right-of-way projects. Also, weed-free forage may be required on state and federal land when mulch is needed on seeded areas following forest fires.
The Kansas Department of Agriculture signed a memorandum of understanding with NAWMA to follow the standards set forth in the North American Weed Free Forage Program. Kansas Department of Agriculture staff also are qualified to certify forage and mulch products to meet any additional requirements set forth by any receiving entity, and we are the only recognized certifying authority in Kansas.
When is certification necessary?
Certification to the North American Weed Free Forage Standard is necessary only when the end user or purchaser requires certification. Currently, all forage or mulch brought onto federal property must be certified to this standard. Many state departments of transportation require mulch to be certified to this standard. Some receiving entities even have standards more stringent than those set out by the North American Weed Management Association.
Does this mean no weeds can be present?
The 54 species identified as noxious weeds by the participating states are a concern, and then only if they have, or will have, viable seed present when the crop is harvested. Portions of a field may be certified if the weeds are in patches. Also, weeds can be treated and the field reinspected. Some receiving entities may have more stringent standards, and we can carry out our inspection and certification to meet their requirements.
When do I need to have my field inspected?
Within 10 days before harvest. When wheat straw is the certified product, the inspection must be done within 10 days before harvest and the straw must be baled during the same 10-day period.
Does certification mean there is a guarantee that no noxious weed seed is present?
No. The inspector certifies that he or she followed required procedures and that the field has passed a reasonable, prudent visual inspection.
Is certified forage the highest quality forage?
No. Quality and nutritive value are not a factor when certifying the product. However, if we find excessive weeds of any species, or poisonous weeds, the field may not be certified.
What do I need to do to have forage certified weed-free?
Contact:
Kansas Department of Agriculture
Plant Protection and Weed Control
Attention: Tom Sim
(785) 862-2180
www.accesskansas.org/kda/Plantpest/plant-main.htm
for an application for a weed-free forage inspection. Complete the application and return it to us as early in the season as possible.
A qualified inspector will contact you to schedule a time for the inspection.
Afterward, you will be given an inspection report.
When the field is harvested, you need to return a copy of the report identifying the number of bales harvested on the certified site.
If you plan to ship or sell small lots, you may want to tag each bale.
If you are selling large lots, you may need only one certification for each load.
Always ask the purchaser if bale tags are required.
An inspection costs $30 an hour plus travel for each inspector. Bale tags are $0.15 and state certificates are $20.
Which weeds are inspectors looking for?
Inspectors will look for as many as 54 weed species, and more if the receiving entity requires it. The 54 weeds are:
