AGR-208: Weed Control for Kentucky Home Lawns

Mike Barrett, J.D. Green, Gregg Munshaw | February 25, 2013 (New)

The best defense against weed problems in home lawns is a healthy and dense lawn. In thick lawns, weed seeds may not germinate because light may never reach the soil surface. A thick lawn is competitive with weeds, keeping them from growing and reproducing. Developing a healthy and dense lawn comes from using cultural practices such as proper grass species and cultivar selection, proper mowing heights and fertilization, and other good management practices. The need for herbicides to control weeds in home lawns can be greatly reduced if the lawn is well maintained.

AGR-202: Corn Growth Stages and Growing Degree Days: A Quick Reference Guide

Chad Lee | September 13, 2011 (New)

Corn growth stages are based on the leaf collar method, where fully emerged leaves (leaf collar visible) are used to stage vegetative development. Growing degree days (GDDs) are used to relate temperature to corn growth and development.

AGR-203: Improving the Productivity of Landscapes with Little or No Topsoil

Edwin Ritchey | August 16, 2011 (New)

Landscapes with little or no topsoil can make it difficult to produce a garden, lawn, or other plants. Topsoil, dark in color compared to the underlying soil, is the part of a soil that is most biologically active, nutrient rich, and easily managed. It also is usually more easily worked than underlying soil, supplies most of the plant's water and nutrients, and is generally best for plant growth.

AGR-201: Switchgrass for Biomass Production in Kentucky

Laura Schwer, Kenton Sena, Ray Smith | March 14, 2011 (New)

Switchgrass (Panicum virgatum L.) is a warm-season, perennial bunch-type grass native to the North American Tallgrass Prairie that has been investigated as a bioenergy crop due to its adaptation to a wide range of environmental conditions and soil types as well as its high stable yields. Switchgrass is recommended for soil conservation and wildlife habitat in both monoculture and in mixed stands of native warm-season grasses and forbs as well as for summer grazing in pasture systems and as a hay crop for cattle.

AGR-191: Using a Grazing Stick for Pasture Management

Adam Probst, Ray Smith | May 18, 2010 (Minor Revision)

Good management of livestock feeding enterprises requires an understanding of feed inventories and their use. This publication is intended to help producers meet animal forage needs in a rotational grazing system by mastering the use of a grazing stick to estimate pasture yield and pasture allocation.

AGR-185: Nitrogen Transformation Inhibitors and Controlled-Release Urea

Lloyd Murdock, Greg Schwab | April 21, 2010 (Major Revision)

The soaring cost of fossil fuels is an indicator that nitrogen fertilizer prices are going to remain high for the foreseeable future. With higher N prices, many producers are trying to evaluate the usefulness of several N additive products in their production systems. High N prices make these products more attractive because it takes fewer pounds of saved N to offset the price of the additive. Producers should have a good understanding of how these products work in order to make informed decisions regarding their use.

AGR-26: Renovating Hay and Pasture Fields

AGR-145: Warm Season Perennial Grasses for Forages in Kentucky

Tom Keene, Garry Lacefield, Ray Smith | March 10, 2009 (Minor Revision)

Native warm-season perennial grasses are well adapted for production in Kentucky's climate and soils. In this publication, native warm-season perennial grasses that have the greatest forage potential for Kentucky are described. Management techniques necessary to establish stands and keep them productive are also discussed.

AGR-197: Compaction, Tillage Method, and Subsoiling Effects on Crop Production

Dottie Call, John James, Lloyd Murdock | January 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.

AGR-17: Double-Cropping Land for Silage Production
