AGR-218: Herbicide Recommendations for Weed Control in Kentucky Bluegrass and Tall Fescue Lawns for Professional Applicators

Mike Barrett, J.D. Green, Gregg Munshaw | Mar. 30, 2015 (New)

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.

AGR-217: Determining Soil Texture by Feel

Josh McGrath, Edwin Ritchey | Jan. 22, 2015 (New)

Soil texture refers to the proportion of sand, silt, and clay in a soil. Texture influences almost every aspect of soil use, both in agricultural and engineering applications, and even how natural ecosystems function. Many scientists consider soil texture the most important soil property as it can influence soil/water relationships, gas exchange, and plant nutrition. Accurately determining soil texture in a lab requires time and money; therefore, it is often necessary to estimate soil texture in the field by feel, which can be very accurate if done correctly.

ID-225: Organic Corn Production in Kentucky

Chad Lee, Will Martin, Sam McNeill, Lee Meyer, Michael Montross, Edwin Ritchey, Tom Sikora | Jan. 15, 2015 (New)

The number of organic dairy cows in Kentucky has been steadily increasing for years, yet there's not enough organic corn produced in the state to feed the growing herds. In short, a new market has developed in the state, but few local farmers are taking advantage of it. While Kentucky farmers are no strangers to corn, growing corn organically utilizes different management, cultural and marketing practices and requires new skills. And, importantly, organic production must follow an approved farm plan that allows farmers to sell their corn as certified organic. This publication is designed to be both an introduction to a new enterprise as well as a practical manual for those interested in pursuing organic corn production on their own farms.

PR-689: 2014 Kentucky Soybean Performance Tests

Benjamin Abourjeily, Joshua Duckworth, Laura Phelps, Claire Venard | Dec. 11, 2014 (New)

The Kentucky Soybean Variety Performance Tests are conducted to provide an unbiased, objective estimate of the relative performance of soybean varieties in Kentucky. This information may be used by growers and seed producers to aid in selecting varieties that will give the highest total production in a specific situation. Soybean cultivars were entered by soybean growers, commercial companies, and state and federal institutions. Thirty soybean tests were planted in 2014 in Kentucky at the six test locations shown below. Planting dates and other information are shown in Table 1. Data for the maturity groups IV Early, IV Late and V at the Caldwell County location are not provided to avoid penalizing any variety (plots were damaged by a storm soon after planting).

PR-686: 2014 Summer Annual Grass Report

Garry Lacefield, Gene Olson, Ray Smith | Dec. 10, 2014 (New)

Summer annual grasses provide an important forage crop option for producers in Kentucky. These grasses are mainly used as emergency or supplemental hay and pasture crops, but little information is available on their yield potential. The purpose of this publication is to summarize the University of Kentucky 2011-2014 forage yield trials with sudangrass, sorghum/sudangrass, millets, and teff.

PR-687: 2014 Long-Term Summary of Kentucky Forage Variety Trials

Garry Lacefield, Gene Olson, Ray Smith | Dec. 10, 2014 (New)

Forage crops occupy approximately 7 million acres in Kentucky. Forages provide a majority of the nutrition for beef, dairy, horse, goat, sheep, and wildlife in the state. In addition, forage crops play an environmentally friendly role in soil conservation, water quality, and air quality. There are over 60 forage species adapted to the climate and soil conditions of Kentucky. Only 10 to 12 of these species occupy the majority of the acreage, but within these species there is a tremendous variation in varieties. This publication was developed to provide a user-friendly guide to choosing the best variety for producers based on a summary of forage yield and grazing tolerance trials conducted in Kentucky over the past 10 to 12 years.

PR-685: 2014 Cool-Season Grass Horse Grazing Tolerance Report

Garry Lacefield, Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith | Dec. 4, 2014 (New)

Cool-season grasses such as bluegrass, tall fescue, and orchardgrass are dominant pasture grasses for horses in Kentucky. Variety evaluations for yield have been carried out for many years, but little work has been done to establish the effect of variety on persistence when subjected to close, continuous grazing by horses. The purpose of this report is to summarize current research on the grazing tolerance of varieties of tall fescue, orchardgrass, and other species when subjected to continuous heavy grazing pressure by horses within the grazing season. The main focus will be on stand survival.

PR-684: 2014 Cool-Season Grass Grazing Tolerance Report

Joey Clark, Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Dec. 4, 2014 (New)

Cool-season grasses such as tall fescue and orchardgrass are the primary pasture grasses in Kentucky. Other species such as perennial ryegrass, festulolium, and prairie brome can be used in pasture systems. Little is known about the effect of variety on the grazing tolerance of these cool-season grass species. The purpose of this report is to summarize current research on the grazing tolerance of varieties of tall fescue, orchardgrass, perennial ryegrass, and other species when they are subjected to continuous, heavy grazing pressure by cattle within the grazing season. The main focus will be on plant stand survival.

PR-683: 2014 Red and White Clover Grazing Tolerance Report

Joey Clark, Garry Lacefield, Gene Olson, Ray Smith | Dec. 2, 2014 (New)

This report summarizes research on the grazing tolerance of red and white clover varieties when subjected to continuous grazing pressure.
