Weed Control


Tips to Controlling Weeds in Grass Pastures

Using good pasture management practices can help eliminate weeds and unwanted plants in grass pastures and hayfields. To get the most quantity and quality from pastures, use management practices that encourage growth of a vigorous, dense stand of forage grasses and limit germination and growth of unwanted plants. Weed seed germinate in thin pasture stands, and unwanted plants are more prone to become established in these areas.


Buttercups in Grazed Pastures

One of the signs that spring has arrived is when the yellow flowers of buttercup begin to appear, but it’s during the winter months that the vegetative growth of buttercup takes place. As a cool season weed, this plant often flourishes in over grazed pasture fields with poor stands of desirable forages.


Tall Ironweed Control in Grazed Pastures

Tall ironweed (Vernonia altissma Nutt.) is one of the more commonly found weeds in grazed pasture fields and other non-cropland areas.




Efficient Pasture Utilization

Increasing nitrogen in the soil has been shown to greatly increase pasture production. Nitrogen can be increased in pastures by incorporating nitrogen-fixing legumes into grass stands or by applying nitrogen fertilizer.


Soil Test to Determine Fertilizer Applications

Fertilizer is one of the main expenses in a productive grazing system. It is important to apply fertilizer and lime in accurate amounts for best forage production and financial and environmental reasons. Performing a soil test on pastures and utilizing the results to evaluate pasture fertility is strongly advised. Analysis of a soil sample will determine nutrient content of the soil including phosphorus, potassium, magnesium, sodium, sulfur, manganese, copper, and zinc. Soil pH, organic matter, and exchangeable acidity will also be included in the results. These results are used to decide what to apply and how much to apply.


Fall Fertilizer Applications

Nitrogen application in late October to November can thicken forage stands, initiate spring growth earlier, and forages will remain greener into the fall and early winter.

Promote Early Grass Growth this Year

Applying nitrogen in mid-February to mid-April can promote early grass growth which can increase overall forage production and may reduce the use of stored feed.

Soil Test to Determine Fertilizer Applications

Fertilizer and lime should be applied in accurate amounts for best forage production and for financial and environmental reasons. Performing a soil test on pastures and utilizing the results to evaluate pasture fertility is strongly advised.





Renovating High Traffic Areas

Ways to renovate high traffic areas such as alleyways gated, waterers, etc. The different options you can use to promote growth and the management practices for these particular areas. Describes the different ways a producer can benefit from this practice.


Forage Tip of the Month – Common vs. Certified Seed

Once you have selected a forage species and variety, it is recommended to buy a quality seed that is high in germination rate and free of weed seed. Buying certified seed guarantees that the requirements for both of these parameters has been met and should be the first purchasing option.


Frost Seeding

The frost seeding method allows seeds to be inter-seeded into undisturbed soils by scattering seed on top of the ground. The freezing and thawing action of the soil works the seeds into the soil where they can germinate. In Kentucky, the ideal time to frost seed is between February 10 and March 1, with mid-February preferred.


When to reseed pastures

Multiple reasons exists for needing to reseed pasture, such as old stands that are dying out or stands that need to be improved due to poor management, disease, to fill in bare spots, or to reduce weed problems.


Warm-Season Annuals

Warm-season annuals such as sorghum, sudangrass, sorghum X sudangrass hybrids, and millets are useful forages for summer grazing.


Warm-Season Perennials

Although grazing warm-season annuals can be extremely beneficial throughout the hot summer months, many are reluctant to use them. The cost and extra time and labor required to seed these forages each year is the main reason. Grazing warm-season perennials may be a good option for some operations.

Partridge Pea or Chamaecrista fasciculata (Michx.) Greene

Partridge pea is a warm-season legume commonly used in wildlife seed mixes. Conservation Reserve Program lands are often seeded with these wildlife mixes.


Successful Seeding

Seed is the basic building block to a forage or crop stand. Whether establishing a new stand or improving an old stand, actions can be taken to ensure that newly planted seed produces a healthy stand.


Growth of Grasses and Legumes

Good grazing management will result in improved pasture yields. Understanding how plants grow allows for better management decisions as to when to move livestock under different growing conditions.

Purchasing Quality Seed

Seed is one of the cheapest inputs and is the basic building block to a good forage stand and grazing operation. Purchasing seed of high quality can increase pasture quality and yield.

Inoculating Legume Seed

In order for legumes to fix nitrogen, the rhizobium bacteria which form a symbiotic relationship with the plant must be present. Inoculating seeds with these bacteria prior to seeding will ensure that this beneficial process is occurring.

The Use and Renovation of Sacrifice Areas

While using a sacrifice area can protect other pastures, these areas usually suffer from soil compaction, cover by manure and hay residues, forage damage from overgrazing and hoof action, and severe erosion. Steps should be taken to manage these areas to reduce these negative effects.

Establishing Warm-Season Annuals

Adding warm-season annuals to a grazing system can provide high quality forage throughout the hot summer months.




Extending the Grazing Season


Starting the Grazing Season off Right

Do not start grazing cattle as soon as pastures start greening up. Grazing too early not only hurts future forage production but can also reduce livestock performance. Early spring management of livestock and pastures can help to maximize success and production for the remainder of the grazing season.


Highlights from University of Arkansas – 300-Day Grazing Educational Program

This summer, the University of Arkansas Cooperative Extension Service provided the opportunity to share their success of the 300 Day Grazing Program with the University of Kentucky Cooperative Extension Service by inviting us for a private two-day tour of the program. Three University of Kentucky Extension specialists, three Agriculture and Natural Resource county Extension agents, a representative from the Kentucky Beef Network, and the Master Grazer Program Coordinator (myself) teamed up to travel throughout Arkansas to learn about the program in preparation of developing a similar program in Kentucky. We toured farms that have implemented managed grazing practices and discussed the results of the program with Arkansas county Extension agents, producers, University of Arkansas Extension specialists, and the 300 Day Grazing program coordinator.


Identify Fields for Stockpiling

With the rising cost and limited availability of hay over the past few years, Kentucky cattle farmers have been looking for ways to extend the grazing season and reduce the need to feed hay during the fall/winter months. Stockpiling forage is one way to meet both of these objectives. The definition of stockpiling is to “grow pasture for a later use.” The species of forage that respond best to stockpiling will vary between different regions of the US. In Kentucky, cool-season grasses respond favorably to nitrogen applications in the fall. Tall Fescue is especially renowned for stockpiling because of its inherent ability to maintain high levels of nutrients during the winter months than other cool-season species.


What to Graze During Heat Stress

As the environmental temperature increases, cool-season forages begin to go dormant and production decreases. Warm-season grasses and legumes should be incorporated into grazing systems in order to reduce overgrazing paddocks and supply amply amounts of high quality grazing.



Grazing Stockpiled Forages

The use of stockpiled forages can extend the grazing season and reduce the amount of stored feed needed to feed livestock through the fall and winter months. Stockpiling forages, or allowing forage growth to accumulate for use at a later time, can help extend the grazing season.


Grazing Corn

Many options exist to provide quality grazing during seasons when many common forages have gone dormant. Some non-traditional forages can provide high quality grazing throughout the early fall, late winter, early spring, or hot summer months.


Fall and Winter Grazing

Many options exist to provide livestock with high quality forages for grazing throughout the fall and early winter months.  In Kentucky, these options include utilizing perennial cool-season pasture as well as a variety of small grains and brassicas. 


Uniform Grazing

Non-uniform grazing can reduce utilization of available forages and increase undesirable plants and weeds in pastures. Taking steps to graze paddocks more uniformly will benefit overall livestock production and forage quality.


Harvesting Drought-stressed Soybean Crops for Hay

With much of the country affected by the drought conditions this summer, many grain producers are facing the problem of low grain yields while many livestock producers are experiencing hay shortages and may be seeking alternatives for winter feed.

Dragging and Clipping Pastures

Feeding costs are the greatest expense for livestock producers. Grazing is the cheapest source of feed. Dragging and mowing pastures are two methods that are often used to attempt to increase forage production and soil fertility. Although these practices are useful agronomically, they may not be practical economically.


Stockpiling Tall Fescue

Using stockpiled tall fescue is a great way to extend the grazing season and reduce the use of stored feed.

Small Grains for Grazing

The use of cereal grains can be an effective way to extend the grazing season. These small grains can be used for grazing, grain, hay, or silage.


Grazing Corn Residues

Grazing remaining residue following corn harvest is one way to extend the grazing season and lower feed costs. Winter feed costs are the largest expense and grazing corn residues offers a way to significantly reduce those costs.


Grazing Small Grains

Small cereal grains, such as wheat, rye, oats, and barley, are multipurpose crops that can be used for grazing, silage, or hay production. Grazing pure stands of small grains is an effective way to extend the grazing season into the late fall and early winter, and then again in February/March for early spring grazing.




How to Use Variety Trial Publications

When renovating or establishing pastures, an important consideration is the selection of forage species and varieties. Forage species, as well as varieties within a species, vary significantly in yield, quality, and stand persistence, which combine to greatly impact performance and economic return to the operation. In addition to choosing an appropriate variety, proper seeding rates and seedbed preparation are necessary for the successful establishment of the selected variety.


Warm-Season Annuals

Warm-season annuals such as sorghum, sudangrass, sorghum X sudangrass hybrids, and millets are useful forages for summer grazing.


Assessing Pastures: Forage Identification

When planning a grazing management plan for your pastures, it’s important to realize that pasture is the most economical and efficient way to feed your animals. When managing pasture, both the animal nutrient needs and pasture requirements should be considered.


Is Using a BMR Sudangrass Right for Your Grazing System?

Brown Midrib, or BMR, varieties have reduced lignin content which increases digestion, fiber availability, and energy available for grazing livestock.


Forage of the Month- Corn (Zea mays L.)  

Corn is one of our most productive forages with the potential to produce more than seven tons of dry matter per acre. Few annual crops can compare to corn in terms of yield (dry matter per acre) and cost (per pound of gain). Grazing fully matured, standing corn during the winter months has proven to be a successful tool to extend the grazing season.


Grazing Alfalfa

Alfalfa is one of the primary forage crops grown in the U.S. This high quality forage produces high yields that can be used for hay, silage, or pasture.






Forage related disorders


Novel Endophyte Tall Fescue

Novel Endophyte Tall Fescue is a variety of tall fescue that has the desirable traits of the wild-type endophyte infected fescue, only without the harmful animal side effects.


Preventing Grass Tetany

Prevention methods to keep cattle from getting a forage related disease called grass tetany. Includes some different options a producer can practice to prevent this disease. Cattle that get this disease often die quickly, but this disease has a variety of symptoms to look for. Includes recommendations for the various prevention methods and tips when to start/stop feeding high “mag” minerals and how much each cow should be getting daily. The season for grass tetany will be developing as temperatures rise and grasses begin to grow.


Forage of the Month-Brassicas: Be Aware of the Animal Health Risks  

Brassicas (including turnips, rape, kale, and swedes) are highly productive, digestible forbs that contain relatively high levels of crude protein. Animals will readily consume the tops and will also grub the root bulbs out of the ground. Dry matter yield depends upon soil type, fertility, time of seeding, and precipitation.


Prussic Acid Poisoning This Summer

Grazing forages during the summer months is a great way to reduce stored feed costs. However, there are some risks that come with grazing certain forages and weeds. It is important to be cautious this summer to reduce the risk for prussic acid poisoning, as prussic acid poisoning tends to be worse during times of drought.


Managing Legumes in Spring Pastures for Bloat

Pastures were slow to green-up with the cool weather this spring.


Freezing Effects on Forages

As temperatures continue to decrease, it is important to know and understand how various species of forages react to frosts and freezes in order to best utilize these forages and to avoid possible health problems. Freezing changes the metabolism and composition of plants. Depending on plant species, this can create possible forage-related animal disorders or the need to alter grazing management practices.


Bloat Prevention

In Kentucky, bloat is most common from mid-March through May but many cases of bloat have already been reported this spring.


Possibility of Nitrate Toxicity in Corn

Drought conditions and high levels of nitrogen in the soil can increase the risk of nitrate toxicity in livestock grazing these forages.




When Will There be an Answer for Pinkeye?

Pinkeye or IBK (infectious Bovine Keratoconjunctivitis) is a costly disease for cattle producers.


Animal Management Tip of the Month– Warning for Prussic Acid or Cyanide Poisoning

Prussic acid poisoning occurs when livestock graze certain plants that contain cyanide-producing compounds. Such species include, but are not limited to, sorghum, sudangrass, sorghum-sudan hybrids, Johnsongrass, and wild cherry. Cyanide can interfere with oxygen utilization in livestock, especially if consumed in large amounts.


Grazing Considerations


Heat Stress

Heat stress in cattle can result in decreased weight gain, milk production, and reproductive performance. Heat stress can be increased when grazing endophyte-infected fescue and being worked during the hottest part of the day. Learn how to protect your cattle from heat stress.


Animal Tip of the Month– Strip Grazing Stockpiled Forage

Stockpiling forage is one way to extend the grazing season and minimize winter hay feeding. Tall Fescue is renowned for stockpiling because of its inherent ability to maintain high levels of nutrients during the winter months. Stockpiling fescue in the fall is fairly simple.


Grazing Systems

Various rotational grazing systems are used to increase forage production. These can include leader-follower, strip grazing, or ultra-high density grazing.


Feeding Co-Product Feeds to Cattle on Fescue Pastures

Tall fescue covers 5 million acres of hay meadows and pastures in Kentucky and has been the predominant forage in the state for over 50 years.

Transition From Stored Feed To Pasture

Pastures have greened up and are once again producing lush, high quality forages for grazing. Although it may be tempting to put livestock back on these pastures right away, certain precautions should be taken to protect the livestock and the new forage growth.


The Importance of Water in Every Pasture

Many farmers that are currently using a rotational grazing system will argue that implementing a water system is the most vital and limiting factor. 


The Importance of Shade and Water

Supplying adequate shade and water for grazing livestock is essential for good herd health and performance.


Animal Management

The Face Fly

Horn flies and face flies are the key pasture flies that Kentucky cattle producers face each year. Both provide unique control challenges but the face fly is the more difficult one to manage. There are two main reasons: the small amount of time spent on animals and hard-to-treat feeding sites


Fly Control in Pastures

Flies are one of the most difficult pests to manage and although they cannot be totally controlled, it is possible to reduce populations and irritation to livestock.




Grazing Systems:


The Use of Temporary Fence

Many different types of temporary fencing materials are marketed which can make the practice of rotational grazing easier for you. Learn about these type products so you can make the best decision for your operation


Minimizing Hay Waste while Feeding

If hay is stored and fed properly, hay loss can be minimized. Total losses from hay storage and feeding are estimated to exceed three billion dollars annually nationwide. This does not include additional economic losses associated with labor used to store and feed hay. While it is normal to expect some hay loss during feeding, minimizing hay feeding losses should be a primary producer goal.


Forage Testing

Testing your forages can be a useful tool to minimize feeding costs while maximizing animal production. Forage testing provides the nutritional value of pasture, hay, or silage.


Assess Past Grazing Season and Plan Ahead

As the grazing season comes to an end, take time to reflect on and assess the past grazing season. It is important to continually make an effort to improve and advance a managed grazing system. When planning for the upcoming grazing season, decide on a purposed budget and time limitation. If you have little or no budget to make improvements to your grazing system, simple changes to management practices can make significant improvements.


Multi-Species Grazing

Grazing two or more animal species in a pasture-based system can increase forage utilization and efficiency.


The Importance of a Rest Period Between Grazing

One of the most important components of a successful rotational grazing system is allowing the forages an adequate rest period for plant recovery and regrowth. Allowing plants a sufficient rest period is vital to maximize forage quality, yield, and stand persistence. 


Harvesting Excess Spring Growth

Cool season grasses are growing rapidly and producing large amounts of forages at this time of year.


Suggested Grazing Heights

Grazing at too low of a height causes overgrazing and decreases stand productivity and longevity.


What is Holistic Grazing Management?

Holistic grazing management is a method of managing the land in a way that mirrors nature. With less artificial inputs and actions, advocates believe that by managing holistically, the land, animals, water, and world will be healthier.

Minimize and Reduce Soil Compaction

Soil compaction is a common problem that many producers face but that is often overlooked. Significant soil compaction can also reduce forage yields and slow forage establishment which, in the long run, costs money. Management practices can be used to reduce and correct this problem while improving soil conditions.


Dealing with Wet Pasture Conditions

In order to keep damage to pastures to a minimum, it is important to take the proper actions to protect them during wet periods when they are prone to damage.


Environmental Concerns with Grazing

With the many challenges of managing an agriculture operation, environmental concerns often fall low on the priority list. However, incorporating a few key practices can help ensure animal health, improve soil resources, and protect water quality. In addition, these practices can be included in a KY Agriculture Water Quality Plan and help farmers comply with environmental regulations.
