AGR-259: Multi-SOA Pre-emergence Herbicides for Palmer Amaranth and Waterhemp Control

Travis Legleiter | Apr. 24, 2024 (Minor Revision)

Waterhemp and Palmer amaranth are among the most troublesome and hard to control weeds in soybean fields in Kentucky. Both species have spread across the state over the past ten to fifteen years. Resistance to ALS-inhibiting herbicides [Group 2] and glyphosate [Group 9] is widespread in both species, while PPO-resistance [Group 14] is continually spreading especially in waterhemp. Herbicide manufacturers have developed several herbicide premix formulations targeted at controlling waterhemp and Palmer amaranth that contain multiple effective sites of action, thus farmers have options to choose from.

AGR-276: Kentucky Land Capability Classes and Limitations

John Grove, Brad Lee, Edwin Ritchey | Mar. 19, 2024 (New)

The USDA NRCS has established a national land classification system to help landowners and farm operators with land use planning. This system classifies land for agricultural purposes by the intensity with which it can be used for crop production and by the nature of the limiting problem. In general, the better the Land Class (lower numeric values), the less management is necessary to produce a crop while protecting the soil resource and the environment.

Kenny Burdine, Kelly Mercier, Ray Smith | Mar. 13, 2024 (New)

The organic dairy sector in Kentucky and Tennessee contributed $9.3 million in organic product sales in 2019 (USDA-NASS, 2020), with organic milk sales in Kentucky alone rising 61% from 2017 to 2019 (USDA, NASS, Kentucky Field Office, 2020). Organic dairies rely more heavily on pastures as a significant source of dry matter intake compared to most conventional dairies.

HENV-716: Companion Canine Nutrient Contributions to Kentucky's Urban Environment

Glynn Beck, Rick Durham, Brad Lee | Mar. 12, 2024 (New)

Eutrophication is a significant environmental issue affecting creeks, streams, and lakes, and excess nutrients, particularly nitrogen (N) and phosphorus (P), play a crucial role in its development. Microbial growth due to excess nutrients in the environment can be devastating to aquatic life and water resources. When eutrophication occurs, excess nutrients in fresh water can cause algal blooms, some of which are toxic to humans and pets.
