Nitrogen for Kentucky Turfgrasses

2/13/2020 (new)
Authors: Gregg Munshaw, Travis Shaddox

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.

Iron for Kentucky Turfgrasses

12/20/2019 (new)
Authors: Gregg Munshaw, Travis Shaddox

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.

Calcium for Kentucky Turfgrasses

12/19/2019 (new)
Authors: Gregg Munshaw, Travis Shaddox

Calcium (Ca) is the dominant cation in all soils of agronomic importance and Kentucky soils are no different. Kentucky soils are naturally high in Ca. Consequently, Ca deficiency in Kentucky turfgrasses is extremely rare, and the probability of observing a Ca response on golf courses, home lawns, sod production, or sports fields is very low. Applying Ca fertilizers to artificially increase soil Ca above the level necessary for proper plant growth normally does not result in an increase in plant uptake because Ca uptake is genetically controlled. Regardless, Ca is commonly applied in both granular and liquid forms.

Magnesium for Kentucky Turfgrasses

12/19/2019 (new)
Authors: Gregg Munshaw, Travis Shaddox

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.

Phosphorus for Kentucky Turfgrasses

12/19/2019 (new)
Authors: Brad Lee, Gregg Munshaw, Travis Shaddox

Phosphorus (P) is an essential plant nutrient and a common component of many turfgrass nutrition programs. Although P application can improve turfgrass quality in some soils, most soils of Kentucky already have adequate plant-available P to support healthy turfgrass growth. What is the function of P within the plant, and how much P is required to sustain acceptable turfgrass in Kentucky? Also, if P applications are necessary, when and how should P be applied?

Chemical Control of Turfgrass Diseases, 2020

11/19/2019 (major revision)
Authors: Gregg Munshaw, Paul Vincelli

Turgrasses under intensive management are often subject to outbreaks of infectious diseases. Good turf management practices often greatly reduce the impact of disease by promoting healthy plants that are better able to resist infections. Even under good management, however, diseases sometimes cause excessive damage to highly managed turfgrasses. The proper use of fungicides in these instances, in conjunction with good cultural practices that promote quality turf, can be an important part of an overall disease-management program.

Improved Turfgrass Varieties Can Reduce Your Environmental Impact

8/29/2019 (new)
Authors: Gregg Munshaw, Travis Shaddox

Turfgrasses have many benefits, but oftentimes people question if pesticides, fertilizers, and water are justified to sustain a quality turfed area. Although these inputs have long been required to produce thick and dark green turfgrass, some turfgrass breeders have focused on improving the genetics of turfgrasses to produce high quality turf with fewer inputs. Improved turfgrass varieties with increased density, better color, deeper rooting, and improved disease resistance through improved breeding can reduce the overall environmental footprint. Many people select a turfgrass species and variety based on cost, but choosing an improved variety can reduce environment risk and overall maintenance costs in the long-run.

Selecting the Right Grass for Your Kentucky Lawn

8/29/2019 (major revision)
Authors: Gregg Munshaw, Travis Shaddox

The best grass for your lawn is not necessarily the one you like the best, but the one that is best adapted to where you live and will take less work and fewer inputs (water, fertilizer, pesticides). Many people think that since Kentucky is the "Bluegrass State," it's best to grow Kentucky bluegrass across our state. Actually, Kentucky bluegrass is only marginally adapted to our climate and can require more inputs to keep an appealing lawn than some other choices. In general, Kentucky bluegrass can be an option for parts of central and eastern Kentucky, while zoysiagrass may be a better option in western Kentucky. Tall fescue is adapted to the entire state so is a good choice for most locations. Perennial ryegrasses and fine fescues are occasionally useful in different areas of the state, depending on specific conditions.

Calibrating Boom Sprayers for Turf Applications

3/12/2019 (new)
Authors: Gregg Munshaw, Travis Shaddox

Calibrating application equipment is something many people avoid because they believe it is too time consuming or that the math involved is too confusing. Calibration, however, is critical. Applying too little can result in poor pest control and can lead to pesticide resistance. Whereas, over applying can be bad for the environment, damage the grass, and wastes money. There are several methods for calibrating sprayers. Choose the one that makes the most sense to you. Three different methods are described below. All these methods are reliable and will provide very similar application accuracy.

Establishing and Managing Bermudagrasses in the Transition Zone

11/12/2018 (new)
Authors: Gregg Munshaw, Travis Shaddox

Bermudagrasses have been successfully grown on athletic fields and golf courses in the transition zone for many years. Although each year some level of winterkill threat exists, bermudagrass remains an excellent surface for golf and sports. Seeded varieties of bermudagrasses have been the most common choices in Kentucky due to the availability of seed of good varieties as well as the ease of planting seed versus living plant material. There are, however, several outstanding vegetative bermudagrass cultivars that are adapted to the transition zone.

Lawn Management: Kentucky Master Gardener Manual Chapter 15

3/5/2018 (major revision)
Authors: Gregg Munshaw, A.J. Powell

Turf is the foundation of a quality landscape. It improves the beauty of other ornamentals and provides a safe recreational surface. Quality lawns greatly increase the economic and sociological value of urban homes. They beautify and reduce the often harsh urban environment by decreasing noise, glare, heat, dust, and mud. Lawns and other recreational turf areas are an integral part of our daily activities.

Grass Options for Athletic Fields in the Transition Zone

3/2/2018 (new)
Authors: Nicole Mundell

There are several grasses that will grow in the transition zone, but none all that well. Our summers are often too hot for cool-season grasses like Kentucky bluegrass and our winters are often too cold for warm-season grasses like bermudagrass. Keep in mind, however, that the problem with most poor athletic fields is not grass selection, but rather over use, lack of maintenance, and/or use when field is wet or cannot recover.

AGR-228

Optimizing Bermudagrass Athletic Field Winter Survival in the Transition Zone

5/31/2017 (new)
Authors: Gregg Munshaw

Bermudagrass is an excellent choice for use on athletic fields throughout the transition zone (which includes Virginia, Kentucky, southern Indiana, and Missouri) because of its tolerance to close cutting heights, summer vigor, positive traction characteristics for athletes, resistance to divoting and ability to withstand and recover from significant traffic during active growth. The major limitation to successful bermudagrass persistence in transition zone locations is a general lack of cold tolerance and susceptibility to winterkill.

Turfgrasses of Kentucky

8/17/2015 (new)
Authors: Gregg Munshaw

Roughly 7,500 grass species are grown around the world, but only 14 species are adapted as turfgrasses that have been used extensively. Kentucky is situated in the transitional climatic zone of the United States, the middle point between the cool north and the warm south, with warm summers and cool winters. Because of its unusual climate, no single grass is suitable for all situations and locations. The majority of the turfgrasses that are appropriate for use in Kentucky are known as C3 grasses, or cool-season grasses. Cool-season grasses differ from warm-season grasses (C4) in many ways, but most notably in their photosynthetic pathways. Warm-season grasses can tolerate and even thrive during the warm summers while cool-season grasses may become heat-stressed. Conversely, winters in Kentucky may be too cool for warm-season grasses and greenup in the spring may be long and arduous. Warm-season grasses enter a dormancy period during the fall and winter and may stay in this state as long as six or seven months.

Herbicide Recommendations for Weed Control in Kentucky Bluegrass and Tall Fescue Lawns for Professional Applicators

3/30/2015 (new)
Authors: Mike Barrett, J.D. Green, Gregg Munshaw

The best method to control weeds is to grow a dense and healthy lawn. This objective should be primary for turf professionals. Lawn weed control is facilitated by identification of the turfgrass and weed species present. Not all herbicides will control all weeds, and not all herbicides are safe on all lawn grasses. This publication contains herbicide recommendations for licensed professionals. For information on weed control for non-professionals, see AGR 208: Weed Control for Kentucky Home Lawns.
