AGR-255: Strategies for Reclaiming Hay Feeding Areas
Kelly Mercier, Chris Teutsch | Dec. 15, 2020 (New)
Hoof damage from livestock during the winter months can result in almost complete disturbance of desired vegetation and soil structure in and around hay feeding areas. Even well-designed hay feeding pads will have significant damage at the edges where animals enter and leave. Highly disturbed areas create perfect growing conditions for summer annual weeds like spiny pigweed and cocklebur. Weed growth is stimulated by lack of competition from a healthy and vigorous sod and the high fertility from the concentrated area of dung, urine, and rotting hay. The objective of this publication is to outline strategies for rapidly establishing stands of desirable forage species on these areas.
AGR-260: Palmer Amaranth and Waterhemp Control in Corn and Soybean
Travis Legleiter | Dec. 14, 2020 (New)
Understanding the biology of a weed is the first step in implementing an effective weed control program. This is especially true with Palmer amaranth (<i>Amaranthus palmeri</i>) and waterhemp (<i>Amaranthus tuberculatus</i>), as understanding their emergence patterns, competitiveness, adaptability, and seed production all need to be considered when developing a control program.
AGR-254: Grain Drill Calibration: Don't Make a Mistake--CALIBRATE!
Jessica Buckman, Chris Teutsch | Dec. 2, 2020 (New)
Grain drill calibration is a critical, yet often ignored part of successful forage establishment and pasture renovation. Planting lower seed rates than recommended can result in thin stands that are susceptible to weed encroachment. Planting more than the recommended seeding rate is undesirable due to increased seed costs. The following calibration method can be applied across a wide range of grain drill types and manufacturers and minimizes the need to carry out detailed mathematical calculations.
AGR-257: Hay Sampling: Strategies for Getting a Good Sample
Jordyn Bush, Jimmy Henning, Tom Keene, Chris Teutsch | Dec. 2, 2020 (New)
Knowing the nutritional quality of forage and hay is an integral part of a profitable and efficient livestock operation. Accurate estimation of forage quality starts with obtaining a representative sample of the forage to be fed. Proper sampling technique is critical. Hay is preserved in different packages ranging from the small square bale weighing 40-50 lb to the large square bale weighing more than 1500 lb. In Kentucky, most hay is packaged in large round bales weighing between 500 and 1500 lb. Wrapped bale silage is also gaining popularity and should be sampled in a similar manner to large round hay bales with the exceptions listed here.
AGR-252: Soil Sampling Pastures and Hayfields
Chris Teutsch, Edwin Ritchey | Dec. 1, 2020 (New)
Adequate soil fertility in pastures and hayfields is key to maintaining productivity and optimizing profitability. Soil testing is the basis of well-designed fertilization and liming programs. In order to develop effective programs, soil samples must be collected in a manner that results in an accurate representation of each pasture or hayfield area.
AGR-261: Double Crop Soybean Production in Kentucky
Carrie Knott | Oct. 20, 2020 (New)
The double crop soybean system was pioneered in Kentucky. Traditionally, double crop soybean are planted in June following harvest of a small grain: wheat, barley, and in some cases cereal rye. Since the early 2000's, about 25% of the total soybean production in Kentucky has been double crop soybean. Many agronomic management strategies are similar between double crop soybean and full season soybean: soybean planted in the spring following corn from the previous year. However, there are certain management strategies that are important for double crop soybean, which not only increase yield potential but also offer opportunities to increase profitability.
AGR-256: Identification of Palmer Amaranth, Waterhemp and Other Pigweed Species
Travis Legleiter | Oct. 16, 2020 (New)
Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus) are two species of the Amaranthus family that have enveloped the corn and soybean growing landscape of the United State over the past decade. Herbicide resistant Palmer amaranth first began infesting western Kentucky along the Mississippi and Ohio rivers in the early 2000's and has spread along the rivers and into the uplands over the last two decades. The introduction and spread of waterhemp had not been as widespread in Kentucky, although a rapid spread of waterhemp over the last 5 to 10 years has been noted especially in central Kentucky. Both Amaranthus species can be very difficult to control in soybean and corn due to herbicide resistance. The first step in effectively managing or controlling both species is to properly identify them when they first invade your fields. Early management decisions when Palmer amaranth and waterhemp first invade is key to long-term control.
AGR-258: Production of Connecticut Broadleaf Cigar Wrapper Tobacco in Kentucky and Tennesse
Andy Bailey, Bob Pearce | Sep. 29, 2020 (New)
There has been recent interest from tobacco dealers in purchasing Connecticut Broadleaf tobacco produced in Kentucky and Tennessee. Connecticut Broadleaf has traditionally been grown in areas of the Connecticut River Valley in Connecticut and Massachusetts. However, decreased production in this area along with increased demand for natural leaf cigar wrappers has caused tobacco dealers to pursue other tobacco-producing areas for this type. At first glance, Connecticut Broadleaf tobacco resembles dark air-cured tobacco, but generally has enhanced leaf quality characteristics that can increase its potential value for use as cigar binders and wrappers.
AGR-253: Identifying Freeze Damage in Wheat
Carrie Knott | Aug. 11, 2020 (New)
Wheat and other small grains can be damaged when air temperatures fall below certain thresholds for two or more continuous hours. These temperatures do not necessarily mean that damage will occur. Rather, these temperatures are general guidelines of when damage may occur. It is important that the crop be scouted to determine the extent of the damage, if any.
AGR-18: Grain, Forage, and Cover Crop Guide
Erin Haramoto, Jimmy Henning, Carrie Knott, Chad Lee, Ray Smith | Jul. 8, 2020 (Major Revision)
A quick resource on agronomic management of grain, forage, and cover crops.
