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?

HENV-402

Water Quality and Nutrient Management at Home

7/2/2019 (new)
Authors: Rick Durham, Brad Lee, Gregg Munshaw, Suzette Walling

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.

Gardening in Small Spaces

1/24/2018 (new)
Authors: Rick Durham, Brad Lee, Ashley Osborne

Although most would agree that gardening is a worthwhile endeavor, traditional gardening with long neat rows spaced 3 or 4 feet apart to allow cultivation by a tractor or tiller may not be feasible for everyone. Individuals that live in urban areas, especially those living in townhomes, condominiums, and apartments may not have the outdoor space needed for this conventional style of gardening. In addition, those with limited mobility may not be able to establish and maintain this type of garden. For many, raised bed gardening and container gardening may be a more practical and manageable choice for those gardening in small spaces and those with limited mobility.

PPFS-OR-W-4

"Wet Feet" of Ornamentals

11/1/2015 (new)
Authors: Brad Lee, Tracey Parriman, Nicole Ward Gauthier

"Wet feet" is the common term for a condition that affects plant species intolerant of wet growing conditions. This problem occurs when soils become saturated with water, which, in turn, displaces available oxygen. Roots require oxygen to function; when oxygen is deficient, roots suffocate. Once root damage occurs, plants decline and may eventually die. While "wet feet" is an abiotic disorder and is not caused by infectious organisms, declining root health and wet soil conditions can inhibit the ability of some plants to thrive. This also provides ideal conditions for many root and collar rot water mold pathogens, such as Phytophthora and Pythium.

Irrigation Tips to Conserve Water and Grow a Healthy Lawn

11/11/2014 (major revision)
Authors: Brad Lee, Gregg Munshaw

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.

HENV-507

Flood Conditions and Your Septic System

9/19/2012 (new)
Authors: Brad Lee

The most common septic systems used in the United States employ soil treatment area to treat and disperse wastewater into the environment. The soil treatment area consists of a network of perforated pipes within gravel-filled trenches. Under normal environmental conditions, well designed and managed septic systems work very well at dispersing wastewater and removing pathogens from the wastewater before they reach groundwater or surface waters.

Soils and Fertility: Kentucky Master Gardener Manual Chapter 4

10/12/2011 (new)
Authors: Brad Lee, Edwin Ritchey

Soil is a mixture of weathered rock fragments and organic matter at the earth's surface. It is biologically active--a home to countless microorganisms, invertebrates, and plant roots. Soil provides nutrients, water, and physical support for plants as well as air for plant roots. Soil organisms are nature's primary recyclers, turning dead cells and tissue into nutrients, energy, carbon dioxide, and water to fuel new life.

Authors: Rick Durham, Brad Lee

Gardeners have long made and used compost to improve garden soil. Composting plant and vegetable matter is an important way to reduce the waste burned or dumped in landfills. Yard wastes and vegetable scraps can make up as much as 20 percent of household garbage. Composting effectively recycles that waste into valuable organic matter that can be used as soil amendments.
