Armyworms in Sod

It is not unusual for fall armyworms to infest newly planted sod in a home landscape, especially during late summer to fall. Not all fall armyworm problems originate from sod farms but instead begin near the home landscape where sod is installed. This resource explains the biology and seasonality of fall armyworm in Georgia and discusses possible management strategies to mitigate infestation.

Locate Pesticide Use Limitation Areas (PULAs) Using the EPA’s Bulletins Live! Two Website

Pesticide applicators should visit the Bulletins Live! Two website to determine if they are located within a pesticide-restricted or limited area, known as a pesticide use limitation area (PULA). These restrictions protect endangered and threatened species from adverse effects. This publication provides users a step-by-step guide on how to navigate this website and access the information needed for applications and recordkeeping.

The Bucket Method

This publication describes the Bucket Method and how someone would use this method to measure the streamflow in a stream, creek, or river to be used in developing a Low Flow Plan required for a agricultural withdrawal permit. Part of the Stream Flow Measurements series.

Determining Lime Requirement Using the Equilibrium Lime Buffer Capacity

Soil pH is an important chemical property because it influences the availability of soil nutrients for plant uptake, and it affects a crop’s root system development. Soil pH also indicates whether lime is needed to correct toxicities caused by aluminum and manganese, or to increase calcium levels in the soil. A new method measures the buffering capacity directly.

Urban Gardening: Assessing Soils for Contamination

Urban gardeners and farmers may have concerns about potentially harmful contaminants in their soils. By determining the historical use of the land, one can test for soil contamination associated with prior use. This publication outlines appropriate testing procedures for soil contamination and recommends best gardening practices for working in urban soils.

Canola Production in Georgia

Growing canola profitably takes planning and good management. All aspects of production, from seed selection to harvest to marketing, must be taken into account if the grower is to make a profit. Land preparation, fertility management, weed and other pest control, and timely harvest and marketing are all components of a good canola production package. Before you grow canola, dedicate yourself to make “best management practices” a part of your production system.

Row Crop Sustainability in the Southeast: A Tool to Measure & Improve On-Farm Sustainability

There are many ways to define what it means to be sustainable. There is increased demand for agricultural production transparency to ensure that food and fiber products are being produced sustainably. To this end, Field to Market: Alliance for Sustainable Agriculture has developed the Fieldprint Calculator through the Fieldprint Platform to help farmers of major commodity crops measure their on-farm sustainability by entering in their yearly management practices. This Extension publication defines sustainability, describes the use of the Fieldprint Calculator, and explains how growers can use this program to measure sustainable progress made on their farms. This publication was produced in collaboration with the University of Tennessee and Field to Market.

Fall Armyworm Management in Pastures and Hayfields

Fall armyworms can quickly decimate a field of any forage crop or pasture, often eating higher quality forage first. Growers and farmers can face severe economic damage and total forage loss. Anyone growing forage or pasture used to feed livestock can use this publication to find answers to the most common questions about fall armyworm in Georgia pastures and hayfields.

Land Application of Pulp Mill Lime Mud

Lime mud is a by-product produced in pulp mills as part of the process that turns wood chips into pulp for paper. The pulp mill cooks wood chips with sodium hydroxide to extract the wood fiber used to make paper from the lignin that binds the wood together. During this process, sodium hydroxide is converted to sodium carbonate. The pulp mill than adds calcium oxide, also known as quicklime, to convert the sodium carbonate back to sodium hydroxide in order to use it again. In the process, calcium carbonate is formed.

More Crop Per Drop: An Introduction to the CropFit App

Crop water requirements are not static during the growing season. They vary with crop growth stages and environmental conditions. Advanced irrigation scheduling tools use data collected from or near the field where crops are growing to provide timely information on how much water crops need and when they need it, and generally result in optimizing irrigation water use.

Fences for the Farm
(C 774)
Fences may be used to protect or divide property, to improve its appearance, to confine animals, or to exclude animals. This publication covers the planning for, type of, materials for, and maintenance of permanent and temporary fences.
Common Terms Used in Animal Feeding and Nutrition
(B 1367)
The purpose of this publication is to serve as an educational
reference and resource to those who are interested
in animal feeding and nutrition. Our primary objective
is to list the common terms used when discussing animal feeding. This listing will also be helpful when reading articles on animal feeding and nutrition, feed analysis reports or tags associated with feeds sold in the market.
White Clover Establishment and Management Guide
(B 1251)
White clover (Trifolium repens L.) is a cool season perennial legume of Mediterranean origin. White
clover has been used as a forage in North America since Colonial times. Benjamin Franklin noted its
prevalence in cleared and disturbed land as early as 1746. There are many animal and agronomic related reasons for establishing a productive stand of white clover in existing grass pastures. This publication covers tips on selecting, establishing and managing white clover to help ensure a productive stand.
The Management and Use of Bahiagrass
(B 1362)
Bahiagrass (Paspalum notatum Flugge) is a long-lived, perennial warm season grass that is grown extensively in the southeastern United States. It is most commonly used as a pasture species, but can be used for hay production, erosion control, and wildlife habitat. Bahiagrass can also be used in "sod-based rotation" sequences that have been found to suppress pest problems (nematode and disease issues) in crops such as peanuts.
Georgia Forages: Grass Species
(B 1351)
The geographic and environmental diversity of Georgia allows for the extensive use of both cool and warm season grass species. In general, cool season grass species provide higher nutritional quality than warm season grasses. In contrast, warm season grasses generally yield more than cool season grasses. Each type and species, however, offers its own unique qualities and benefits to the forage system. In this section, the most important grass species in Georgia are introduced and discussed.
Sprayer Nozzle Selection
(B 1158)
Nozzle selection is one of the most important decisions to be made related to pesticide applications. The type of nozzle affects not only the amount of spray applied to a particular area, but also the uniformity of the applied spray, the coverage obtained on the sprayed surfaces, and the amount of drift that can occur. Each nozzle type has specific characteristics and capabilities and is designed for use under certain application conditions. This publication describes the types that are commonly used for ground application of agricultural chemicals, including flat-fan, even flat-fan and cone nozzle.
