AGR-51: Improving Turf Through Renovation
Gregg Munshaw | Nov. 3, 2014 (Major Revision)
Often a poor lawn can be improved by using proper maintenance practices, including mowing, fertilizing, watering, and pest control. In some instances, however, portions of the lawn must be reseeded. Usually one of two methods is used to re-establish a lawn: conventional or renovation. The conventional method involves killing existing vegetation, tilling the soil, and replanting. The advantages of conventional tillage include more complete control of weeds and undesirable grass, a smoother soil surface, and the opportunity to improve the existing soil by adding organic matter and sand. Renovation involves replanting without completely tilling the soil and often without destroying all existing vegetation.
AGR-54: Aerifying and Dethatching Lawns
Gregg Munshaw | Nov. 3, 2014 (Major Revision)
Lawns in Kentucky will occasionally suffer due to compacted (hard) soils and excessive thatch layers. Although most lawns will not have problems with these issues, you may occasionally need to dethatch or aerify (core) to maintain a high quality lawn.
AGR-215: Evaluating Land Resource Potentials in Kentucky
Edwin Ritchey, Ray Smith | Aug. 15, 2014 (New)
The most successful land use decisions are those where the intended use matches the capabilities of the land. Determining the capability of the land begins with a visual assessment of the landscape such as topography (percent slope) and surface drainage patterns followed by a closer examination of the soil physical and chemical characteristics. The purpose of this publication is to provide a basic understanding of the relationship between these landscape and soil properties to facilitate wise land use decisions.
AGR-214: Liming Kentucky Lawns
Gregg Munshaw, Edwin Ritchey | Jul. 22, 2014 (New)
Most homeowners desire an aesthetically pleasing landscape and will take steps to ensure success. Proper fertilizing, watering, and pest control are all steps that will lead to a quality lawn. However, some confusion surrounds when and why lime should be applied to a lawn. Many homeowners believe that lime needs to be applied on an annual basis for a quality lawn. The purpose of this publication is to explain why lime is needed and whether it is required on your lawn.
AGR-212: Fertilizing Your Lawn
Gregg Munshaw | Jul. 22, 2014 (New)
Lawns require fertilizer to remain healthy. Proper fertilization practices will lead to a thick, dark green, uniform lawn that is competitive against weed and disease invasions. The nutrients contained in fertilizers are necessary to support many processes occurring within the plants. If any essential nutrient is limiting, the plants will not perform at their highest level.
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.
AGR-211: Calibrating Fertilizer Spreaders for the Home Lawn
Gregg Munshaw | Mar. 25, 2014 (New)
How much fertilizer should you use on your lawn? Too much can result in turf burn, wasted product and money, and potential environmental concerns. Too little will result in a low-density lawn that will not be attractive or competitive against weed invasions. To insure that you apply the proper amount of fertilizer to your lawn, you must calibrate your fertilizer spreader. You should calibrate your spreader each time you use a new (different) fertilizer because not all fertilizers have the same particle size or density. The information on the fertilizer bag is a good starting point for the calibration process but remember that spreaders can differ significantly. Calibrating your spreader will take a little bit of work, but the series of fairly simple steps below will help you complete the task.
AGR-210: Fertilizer Management in Alfalfa
David Ditsch, Lloyd Murdock, Edwin Ritchey, Greg Schwab | Jan. 8, 2014 (New)
Alfalfa is a high quality, valuable forage crop that can be successfully produced on most well-drained soils in Kentucky for hay, silage, and grazing. Fertilizing alfalfa can be uniquely challenging because it is a high-yielding crop that removes a tremendous amount of soil nutrients when compared to other crops grown in Kentucky. A thorough understanding of alfalfa's growth habits, nutrient requirements, and soil nutrient supply mechanisms is necessary to effectively manage fertilizer inputs and maximize profitability while minimizing environmental impact.
AGR-209: Mowing Your Kentucky Lawn
Gregg Munshaw | Apr. 15, 2013 (New)
Mowing is a recurring cutting of a portion of a grass shoot. Lawns are mowed to maintain topgrowth within a specific range, to control weed plants that are intolerant to mowing, or to sustain an ornamental turf. Mowing is usually thought of as the most simple of lawn maintenance practices; however, even though we perform it more than any other, it can result in mistakes.
AGR-208: Weed Control for Kentucky Home Lawns
Mike Barrett, J.D. Green, Gregg Munshaw | Feb. 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.
