Beneficial Reuse of Municipal Biosolids in Agriculture
Farmers have known for centuries that animal manures spread on pastures and cropland can improve soil fertility. In the 1920s, farmers began to use sludge from municipal wastewater treatment plants as a fertilizer. Through decades of research, the scientific and agricultural communities have come to understand that municipal sludge or "biosolids" contain valuable nutrients and organic matter that improve the soil in a way similar to animal manures. It is important to understand that biosolids are not raw sewage. Biosolids are organic solids that have been treated to stabilize organic matter and reduce disease-causing organisms or pathogens.
This publication was developed to help answer some common questions regarding the use of biosolids and to give farmers benchmarks for good practices. Published on Jul 30, 2014.
Calibration Method for Sprayers and Other Liquid Applicators
This publication discusses the proper calibration methods sprayers and other liquid applicators. Published on Jul 30, 2014.
Calibration of Bulk Dry Fertilizer Applicators
Uniform and accurate application of bulk fertilizer, lime, pesticides and other soil amendments is essential. Proper selection of application equipment and the calibration and evaluation of its performance are essential for satisfactory results. Even the best equipment needs calibration checks. This is especially important when changing from one type of material to another, to different rates of application, and when altering speeds or other
operating conditions. This publication discusses proper selection and calibration of bulk dry fertilizer application equipment. Published on Jul 30, 2014.
Calibration of Manure Spreaders
This publication primarily focuses on rear discharge, twin spinner spreaders common for poultry litter application in the southeast. Published on Jul 30, 2014.
Chemigation in Georgia
Chemigation is an inclusive term referring to the application of a chemical into or through an irrigation system. It includes the application of fertilizers, acids, chlorine and pesticides. Chemigation can save time, reduce labor requirements, and conserve energy and materials. Chemigation is beneficial, however, only to the extent that the irrigation system is adequately designed, fully functional and properly managed. Published on Jul 30, 2014.
Drip Chemigation: Injecting Fertilizer, Acid and Chlorine
Drip irrigation is an important component of vegetable production systems in Georgia. Drip irrigation is more desirable than other irrigation methods for several reasons. Two important advantages are (1) water conservation and (2) potentially significantly improving fertilizer management. Fertigation is the timely application of small amounts of fertilizer through drip tubes directly to the root zone. Compared to conventional ground application, fertigation improves fertilizer efficiency. Published on Jan 31, 2017.
Fertilizer Injectors: Selection, Maintenance and Calibration
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. Published on Jan 31, 2017.
Fertilizing Blueberries in Pine Bark Beds
Grower experiences have proven milled pine bark to be an excellent growing substrate for southern highbush blueberries. Although milled pine bark shares many characteristics with good blueberry soil, fundamental differences exist and need to be understood for rapid growth of young plants and high blueberry yields. Published on Jul 30, 2014.
Granular Applicator Calibration Procedure
Applicators used in granular applications should be calibrated to ensure uniformity and accuracy. An accurate and uniform application can reduce the quantity of an active ingredient required for a given degree of control. Published on Jul 30, 2014.
How to Convert an Inorganic Fertilizer Recommendation to an Organic One
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. Published on Sep 30, 2014.
Land Application of Livestock and Poultry Manure
This publication provides information on (1) the nutrient content of manures available for land application, (2) how to determine manure application rates and whether supplemental fertilizer will be needed for maximum crop production and (3) how to use management techniques to maximize the fertilization potential of farm manures. Published on Feb 28, 2015.
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.

This publication contains comprehensive information about air blast and weed control sprayers for orchards. Published on Jul 30, 2014.
Recommended Practices for Using Wood Ash as an Agricultural Soil Amendment
This publication covers a procedure for applying wood ash as a lime substitute on agricultural lands. This method can be used by manufacturers and dealers who wish to supply wood ash or by landowners who wish to receive wood ash. If the practices in this publication are followed, there should be no adverse environmental effects or regulatory consequence from the land application of wood ash. Published on Sep 30, 2016.
Regulations for On-Farm Storage Tanks in Georgia
This publication provides a brief overview of the major regulatory agencies and highlights the rules that Georgia farmers should be aware of concerning storage tanks on their farms. Published on Feb 28, 2015.
Sprayer Nozzle Selection
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. Published on Jul 30, 2014.
