AGR-241
Improved Turfgrass Varieties Can Reduce Your Environmental Impact
8/29/2019 (new)

 UK Authors: Gregg Munshaw, Travis Shaddox
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: garden and landscape, turfgrass

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.

 Tags: garden and landscape, turfgrass

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.

 UK Authors: Rick Durham, Brad Lee, Gregg Mun
 Departments: Horticulture, Plant and Soil Sciences
 Series: Home and Environment (HENV series)
 Tags:

Fertilizers and other lawn amendments benefit the residential landscape by providing or supplementing the essential nutrients for plant growth and maintenance. Commercial fertilizers are commonly formulated based on three major nutrients, nitrogen (N), phosphorus (P), and potassium (K) and each plays an important role in plant development. However, improper application of fertilizers and amendments may increase the risk of non-point source pollution of surface and ground waters.

 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: nursery and landscape, ornamental plants,

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.

 Tags: nursery and landscape, ornamental plants,

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.

 Tags: garden and landscape, turfgrass

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.

 Series: Agronomy (AGR series)
 Tags: nursery and landscape, ornamental plants,

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.

 UK Authors: Gregg Munshaw
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: nursery and landscape, ornamental plants,

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.

 Series: Agronomy (AGR series)
 Tags: weeds

Most of the winter annual broadleaf weeds are distinguishable from each other and thus fairly easy to key out or identify. However, there are two that show up each spring that often get people scratching their heads as to which is which---is it purple deadnettle? Or is it henbit? There are several similarities between these weeds---both are members of the mint family, both have square stems, both have sparsely hairy oval- to egg-shaped leaves, leaves of both are opposite, and both have small purple flowers that appear in the axils of the upper leaves during the spring.

Turfgrasses of Kentucky
8/17/2015 (new)

 UK Authors: Gregg Munshaw
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: nursery and landscape, ornamental plants,

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.

 Series: Turf Disease: Plant Pathology Factsheet (PPFS-OR-T series)
 Tags: plant diseases

Brown patch, also called Rhizoctonia blight, is a common infectious disease of turfgrass. All turfgrasses grown in Kentucky lawns can be affected by brown patch. However, this disease is usually destructive only in tall fescue and perennial ryegrass during warm, humid weather. While brown patch can temporarily harm a lawn's appearance, it usually does not cause permanent loss of turf except in plantings less than 1 year old.

 UK Authors: Brad Lee, Gregg Munshaw
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags:

The goal of water conservation in the landscape does not need to be as drastic as eliminating all irrigation, but we should choose plant material wisely and decide if and when irrigation is necessary. This publication is designed to promote a healthy lawn through watering while promoting water conservation through best management practices. One of the easiest things you can do to reduce the need for irrigation in your yard is to plant species that naturally need less water. When choosing plants, remember that just because a particular plant is drought tolerant does not mean that it is suitable for Kentucky's climate.

 UK Authors: Gregg Munshaw
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags:

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.

Most people do not realize the environmental benefits of lawns. Lawns are known to cool the air, reduce soil erosion, remove dust and pollutants (including CO2) from the air, reduce run-off of water and pollutants, create oxygen for humans, and improve soils over time by supplying organic matter. Lawns are also important aesthetically and have been shown to improve human well-being. However, to be 100 percent environmentally friendly, we could never fertilize or water our lawns and only mow with a self-propelled reel mower. Or, we could get rid of our lawn altogether. Neither of these options is particularly appealing for most people. We can, however, have a high quality lawn and reduce our impact on the environment by doing some very simple things at the right times of the year. The following guide will walk you through a series of steps that are important for keeping your lawn looking thick and healthy and at the same time reducing pests and the need for chemicals and other inputs.

 Series: Agronomy (AGR series)
 Tags: nutrient management

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.

 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags:

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.

 Tags:

The shade trees and fruit trees that we treasure in our landscapes were originally adapted to growing in forests in close association with other trees. In the forest they can remain small for many years. As soon as there is an opening in the canopy allowing light to reach the forest floor they grow rapidly. This great height allows trees to assume a place of dominance over other plants; their trunks lift their leaves high into the air, allowing them to intercept the maximum amount of sunlight before it reaches other plants. Thus, trees grow tall and provide us with their much-appreciated shade.
