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.
SR-107: Sensor Technology for Variable Rate Nitrogen Applications on Wheat in Kentucky: Recommendations and Verification
Dottie Call, John James, Lloyd Murdock, Ole Wendroth | Oct. 28, 2013 (New)
Nitrogen (N) applications on wheat using sensor-based technology can improve both N use efficiency and yields.
ID-177: Comparing No-Till and Tilled Wheat in Kentucky
Dottie Call, Larry Grabau, John Grove, Jim Herbek, Don Hershman, John James, Doug Johnson, Jim Martin, Lloyd Murdock, Dave Van Sanford | Aug. 26, 2009 (New)
Historically, wheat planting in Kentucky has involved tillage. With conventional tillage practices, most residues from the previous crop are cut and buried prior to seeding wheat. No-till wheat planting eliminates tillage and reduces soil erosion, particularly on sloping soils, as well as reducing labor, machinery, and energy costs.
AGR-197: Compaction, Tillage Method, and Subsoiling Effects on Crop Production
Dottie Call, John James, Lloyd Murdock | Jan. 11, 2008 (New)
No-tillage is the preferred method of crop production for most Kentucky farmers. No-tillage has been proven to increase soil quality and decrease the risk of soil compaction as compared to crop production using annual tillage. However, with the use of heavy farm equipment, soil compaction is always a threat with either tillage or no-tillage. The possibility of soil compaction and its effect on crop production is a constant concern to
many farmers using no-tillage. If soil compaction occurs, is there a difference between the two tillage systems on how it affects crop production and the recovery of the soil with and without subsoil tillage? The following study was conducted to help producers and advisors understand soil compaction and its effects on corn and soybean production as well as the ability of the two tillage systems to recover from soil compaction.
