AGR-250

Remediation of the Fragipan Using Annual Ryegrass

4/29/2020 (new)
Authors: Dottie Call, John Grove, A.D. Karathanasis, Chris Matocha, Lloyd Murdock

The fragipan is a naturally occurring restrictive soil horizon that virtually stops water movement and root growth through the soil. It is commonly located 18-32 inches below the surface of most of Kentucky's fragipan soils. The dense nature of this layer is due to the cementation and binding of the soil particles with a silicate rich amorphous aluminosilicate in association with iron. The binding agents seal the pores and pack soil particles close together. The fragipan is found in 2.7 million acres in Kentucky, and about 50 million acres in the United States.

ID-177

Comparing No-Till and Tilled Wheat in Kentucky

8/26/2009 (new)
Authors: Dottie Call, Larry Grabau, John Grove, Jim Herbek, Don Hershman, John James, Doug Johnson, Jim Martin, Lloyd Murdock, Dave Van Sanford

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

1/11/2008 (new)
Authors: Dottie Call, John James, Lloyd Murdock

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.
