AGR-280: University of Kentucky Blue Water Farms: Status of the Edge of Field Nutrient and Sediment Monitoring Network in Western Kentucky (Project Years 2018-2023)

Leighia Eggett, Glynn Beck, Brad Lee, Erin Haramoto, John Grove | Sep. 23, 2024 (New)

Rainfall simulations were the common way of collecting agricultural runoff water quality samples four decades ago. In these simulations, surface water runoff flow characteristics and water quality constituents of interest (nutrients, sediment) were determined by sprinkling water ten feet from the soil surface over small area delineated by a frame and gutter system in the soil of cropped field. There were several limitations to this method, including small study areas and lack of repeatability throughout the growing season due to farming activities. Many different research designs have since been developed to remedy some of these limitations, such as edge of field (EOF) monitoring.
To gather continuous and field scale EOF data, researchers from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment and the Kentucky Geological Survey are partnering with the U.S. Department of Agriculture – Natural Resources Conservation Service, Kentucky Soybean Promotion Board, the Kentucky Agricultural Development Fund, and nine anonymous landowners to establish a network of 29 EOF water quality monitoring stations distributed throughout Western Kentucky, collectively known as Blue Water Farms.

AGR-250: Remediation of the Fragipan Using Annual Ryegrass

Dottie Call, John Grove, A.D. Karathanasis, Chris Matocha, Lloyd Murdock | Jul. 2, 2024 (Minor Revision)

The fragipan is a naturally occurring restrictive soil horizon that virtually stops water movement and root growth through the soil. It commonly is located 18-32 inches below the surface of most of Kentucky's fragipan soils.

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.

AGR-273: Soil Acidity: What It Is, How It Is Measured, Why It Is Important

John Grove, Edwin Ritchey | Apr. 13, 2023 (New)

Soil chemical health is strongly related to soil acidity. This acidity consists of acidic cations, hydrogen (H+), aluminum (Al3+), and in some soils, manganese (Mn2+). The acid cations are neutralized by basic anions, carbonate (CO32-), hydroxyl (OH-), and oxide (O2-) provided by materials such as agricultural, hydrated/slaked, and quick/burnt limes, respectively. Lime application rates are based on the amount of acidity measured in your soil sample.

ID-139: A Comprehensive Guide to Corn Management in Kentucky

Carl Bradley, J.D. Green, John Grove, Greg Halich, Erin Haramoto, Cam Kenimer, Carrie Knott, Chad Lee, Travis Legleiter, Sam McNeill, Michael Montross, Hanna Poffenbarger, Dan Quinn, Edwin Ritchey, Montse Salmeron, Jordan Shockley, Tim Stombaugh, Raul Villanueva, Ole Wendroth, Kiersten Wise | Dec. 13, 2022 (Major Revision)

Corn is a summer annual crop that is grown widely across Kentucky, the United States, and around the world. In the United States, field corn is grown on about 85 million acres (34 million hectares) while sweet corn is grown on about 600,000 acres (240,000 hectares) and popcorn is grown on about 200,000 acres (81,000 hectares). Most of the field corn across the United States is yellow dent corn. In Kentucky, both yellow dent corn and white dent corn are grown. Corn acres in Kentucky peaked at 3.85 million in 1917 and have been around 1.2 to 1.5 million acres since the 1970s (USDA-NASS, 2020). Most corn in Kentucky today is grown in minimum tillage or no-tillage conditions. Most corn acres are rotated with soybean or wheat and double-crop soybeans.

ID-125: A Comprehensive Guide to Wheat Management in Kentucky

Bill Bruening, J.D. Green, John Grove, Jim Herbek, Don Hershman, Doug Johnson, Chad Lee, Jim Martin, Sam McNeill, Michael Montross, Lloyd Murdock, Doug Overhults, Greg Schwab, Lee Townsend, Dick Trimble, Dave Van Sanford | Feb. 23, 2016 (Reprinted)

The soft red winter wheat grown in Kentucky is the fourth most valuable cash crop in the state. Winter wheat has been an integral part of crop rotation for Kentucky farmers. Wheat is normally harvested in June in Kentucky and provides an important source of cash flow during the summer months.

AGR-213: Soybean Nutrient Management in Kentucky

John Grove, Carrie Knott, Chad Lee, Edwin Ritchey | Apr. 24, 2014 (New)

Soybean grows best on fertile soils. For decades, the University of Kentucky has conducted field studies to establish the relationship between soil nutrient supplies and soybean yield. Adequate soil fertility must be present so that yields are not limited.
