Testing for Water Quality
(C 858-2)
The quality and safety of drinking water is of great concern to many Americans today because of an increased interest in health and environmental quality. This new focus on water quality has led many Americans to consider testing their water. This publication is intended to help you understand water testing and to identify the tests needed.
Conservation and Best Management Practices in Georgia: Implementing, Funding, and Assistance
(B 1335)
Best Management Practices (BMPs) can be described as management and/or structural practices that are designed to reduce pollutants and erosion while increasing the quality of all life. The BMP concept deals specifically with nonpoint source pollution, such as runoff from agricultural fields, forest areas or urban areas. BMPs are also voluntary in nature. Individual practices and applications can vary widely from field to field. Best management practices are typically used in agricultural areas, and forest and urban settings.
Measuring Field Losses from Grain Combines
(B 973)
Harvest losses can rob you of profit from grain and bean production. Harvest losses of 10 percent or more are not unusual, when they should be in the 2 to 4 percent range. If you do not check losses behind your combine, you have no idea what the losses are and where they occur during harvesting. The following procedure outlines how to measure losses during harvest. It also shows you where the losses occur. The grain or beans saved mean that much more profit saved.
How to Convert an Inorganic Fertilizer Recommendation to an Organic One
(C 853)
Many farmers and gardeners use natural minerals and organic fertilizers rather than synthetic ones to build their soil. If you use organic materials as all or part of your fertilization program, this publication will help you calculate the proper amount to use from the recommendations provided by a soil test.
Hobby Greenhouses
(B 910)
The gardener who has a greenhouse can extend or intermingle the seasons at will. Whether you wish to build your own greenhouse from scratch or purchase a prefabricated structure ready for assembly, this publication explains everything you need to know about building and maintaining a hobby greenhouse. This publication also includes several building design plans.
Essential pH Management in Greenhouse Crops: pH and Plant Nutrition
(B 1256)
Your goal as a greenhouse grower is to maintain a stable pH over the life of the crop. This is not an easy task since many factors can affect pH in the growing substrate. The pH can go up or down within several weeks of the crop cycle and if you wait for deficiency or toxicity symptoms to develop, you have already compromised the health of the crop and you r profits. Knowing all factors involved is the first step to managing the substrate pH.
Fertilizer Injectors: Selection, Maintenance and Calibration
(B 1237)
Fertilizer injectors are devices used to apply water-soluble fertilizers, pesticides, plant growth regulators, wetting agents and mineral acids during crop production. They are a vital part of modern greenhouse or nursery operations. Despite the advantages, many growers have had at least one experience with a compromised, damaged or even ruined crop where the cause was traced to a malfunctioning injector. Just like other mechanical devices, proper and frequent maintenance and calibration are crucial steps to ensure optimal injector performance and, thus, healthy crops.
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.
Poultry Litter Application on Pastures and Hayfields
(B 1330)
Poultry litter is widely used on pastures and hayfields in Georgia. There are many benefits when it is used wisely. Producers should use nutrient management planning and recommended rates to ensure poultry litter is used in ways that maximize its benefits without harming the environment.
Global Warming: How Does It Relate to Poultry?
(B 1382)
This publication provides information relevant for agriculture and other industries that are under increasing public pressure to reduce emissions of certain atmospheric gases. Explanations are given about greenhouse gases, carbon footprints, reducing fossil fuel use, alternative energy sources, manure management and carbon credits. Knowing your carbon footprint or energy use can help poultry producers reduce the amount of energy they use and improve their bottom line.
