AGR-206: Lawn Management: Kentucky Master Gardener Manual Chapter 15
Kenneth Clayton, Gregg Munshaw, A.J. Powell | Jan. 16, 2024 (Major Revision)
Turfgrass is the foundation of a quality landscape. It improves the beauty of other ornamentals and provides a safe recreational surface.
ID-1: The Kentucky Extension Master Gardener Program
Sharon Bale, Tom Barnes, Jessica Bessin, Kenneth Clayton, Rick Durham, Bill Fountain, J.D. Green, Kelly Jackson, Krista Jacobsen, Jonathan Larson, Brad Lee, Kimberly Leonberger, Adam Leonberger, Gregg Munshaw, A.J. Powell, Edwin Ritchey, Rachel Rudolph, Robbie Smith, Matthew Springer, Lee Townsend, Nicole Ward Gauthier, Stacy White, Mark Williams, Erica Wood, Shawn Wright | Aug. 24, 2023 (New)
Plants are essential to life on earth. Either directly or indirectly, they are the primary food source for humans and other animals. Additionally, they provide fuel, replenish the earth's oxygen supply, prevent soil erosion, slow down wind movement, cool the atmosphere, provide wildlife habitat, supply medicinal compounds, and beautify our surroundings.
AGR-50: Lawn Establishment in Kentucky
Gregg Munshaw | Jul. 29, 2022 (Minor Revision)
The methods you use, the grass you select and the time of year that you plant your lawn will often determine the quality and ease of maintenance. When it comes to establishing a new lawn, the key is to do everything properly from the start so you will not have to try to fix the lawn once it is established.
AGR-251: Quick Identification Tips for Turfgrasses Commonly Grown in Kentucky
Gregg Munshaw, Travis Shaddox | Jun. 19, 2020 (New)
Species of both warm- and cool-season turfgrasses are grown in Kentucky. Identification of these grasses is critical for implementation of proper management practices. Grass identification is commonly performed by observing specific parts of the plant. For a review of the parts of the grass plant, see AGR-216: 'Turfgrasses of Kentucky'. The objective of this extension publication is to provide concise identification tips to properly identify Kentucky turfgrasses.
AGR-248: The Fate of Nitrogen Applied to Kentucky Turfgrass
Gregg Munshaw, Travis Shaddox | Feb. 14, 2020 (New)
The quality of Kentucky's surface and ground waters are of utmost importance to flora and fauna living in these waters. The growth of flora and fauna is directly related to the amount of available nutrients in these waters. In addition, we use these waters as the primary source of drinking water for ourselves and our families. A wide range of compounds may be found in these waters, the most common of which may be nitrate (NO3-). The sources of nitrogen (N) may include, but are not limited to, atmospheric deposition, septic tanks, effluent water disposal, agricultural fertilization, and landscape fertilization. The objective of this publication is to identify and describe the sources and potential fates of N applied to Kentucky turfgrass.
AGR-249: Potassium for Kentucky Turfgrasses
Gregg Munshaw, Travis Shaddox | Feb. 14, 2020 (New)
Potassium (K) is an essential plant element and is the most abundant mineral, macro-nutrient in turfgrass after nitrogen (N). Sufficient concentrations of K are important to maximize turfgrass tolerance to stresses caused by temperature, drought, traffic, and salinity. Understanding the function, soil content, and fertilizer forms of K is essential to creating an efficient nutrient management program.
AGR-247: Manganese for Kentucky Turfgrasses
Gregg Munshaw, Travis Shaddox | Feb. 13, 2020 (New)
Manganese (Mn) is a common component of micronutrient packages applied to turfgrass and has been documented to result in increased greening of turfgrass. In order to effectively manage Mn applications, it is important to understand the function of Mn in turfgrass, the dynamics of Mn in the soil, and the various forms of Mn available for turfgrass applications.
AGR-245: Nitrogen for Kentucky Turfgrasses
Gregg Munshaw, Travis Shaddox | Feb. 13, 2020 (New)
Nitrogen (N) fertilizer is required by turfgrass in larger quantities than any other mineral nutrient because the plant demand for N is high and the supply of N from the natural environment is normally low. In instances where N is not applied according to the University of Kentucky recommendations, applied N can increase the risk of surface and ground water contamination. The objective of this document is to describe the function of N in turfgrass, explain how soil and tissue tests can be used to manage N applications, and to describe the various N fertilizer sources available for application to turfgrass.
AGR-246: Iron for Kentucky Turfgrasses
Gregg Munshaw, Travis Shaddox | Dec. 20, 2019 (New)
Iron (Fe) is commonly applied using granular or foliar sources to enhance turfgrass color. Iron applications can result in darker green turfgrass as a result of increased Fe uptake or Fe oxidation on the leaf surface. In many cases, Fe results in no turfgrass response at all. Understanding the dynamics of Fe both in the plant and in the soil can enhance your nutrient management programs. The objective of this publication is to explain the function of Fe within the plant, describe the Fe sources available for turfgrasses, and identify which Fe fertilizers are most effective.
AGR-243: Magnesium for Kentucky Turfgrasses
Gregg Munshaw, Travis Shaddox | Dec. 19, 2019 (New)
Magnesium is an essential element for all plants. Soluble magnesium (Mg) exists in soils primarily as Mg2+, a positively charged divalent cation. Kentucky soils are naturally high in Mg and, thus, Mg applications to turfgrass are normally unnecessary. However, turfgrasses grown in sand-based rootzones, such as golf course putting greens and sand-based sports fields, are prone to Mg deficiency. When Mg is necessary, it is essential to understand the function of Mg in the plant, the dynamics of Mg in the soil, and the forms of Mg fertilizers.
