Aerating Grain in Storage (B 712) Aeration conditions grain and seed by lowering the temperature of the material and equalizing the temperature within the storage structure. This prevents moisture migration and condensation and can reduce losses during storage.

Agricultural Safety: Preventing Injuries (B 1255) Most farm injuries and fatalities are preventable when you adhere to safe operating practices. The following are general guidelines for improved safety on the farm.

An Introduction to Organic High Tunnel Tomato Production in Georgia and Florida: Horticultural Tactics (B 1552) This publication is an introduction to high tunnel production that focuses on horticulture aspects of organic tomato production. Diseases and insect pests are not covered, but high tunnel construction, siting, shading, fertility, and irrigation of organic tomatoes are addressed.

Calibration of Dry Broadcast Fertilizer Applicators (C 798) Spinner-disc spreaders are commonly used for applying lime and fertilizer to agricultural fields. Uniform and accurate application of lime and fertilizer is essential. The performance failures of agricultural materials can be directly related to improper and uneven application, careless equipment operation, and the separation of blended material due to size and density differences. The uneven dist…

Chainsaw Chains and Bars (C 1208) The action end of a chainsaw, or the part that cuts, is made of the bar and the chain. Chainsaw chains come in many sizes and configurations and not all saws can handle all bars. To make the right choices for the job, a saw operator should be aware of the cutter type, pitch, gauge, and cutter configuration when purchasing a chain or a chainsaw.

Common Agricultural Calculations Using Unit Conversions (C 1313) Use this publication to calculate planting densities, fertilizer application rates, sprayer calibration, and soil amendment applications using unit conversions. We demonstrate the “raw math” behind common calculations to provide you with the tools for solving any equation using simple addition, subtraction, multiplication, and division. No longer will you be dependent on having production guides, …

Constructing a Passive Solar Greenhouse for Season Extension (B 1566) This publication describes how a passive solar greenhouse was constructed using an earthen wall and water barrels for heat retention. The benefits and potential pitfalls of such a structure are discussed. Additional authors include Alexandra Williams, Syngenta, U.S.A, and Krista Jacobsen, Department of Horticulture, University of Kentucky.

Drip Fertilizer Schedule Recommendations for Vegetable Crops in Georgia Coastal Plain Soils (C 1325) A soil test is a chemical technique used to determine the status of available nutrients in a soil sample. It is a common method used to predict how soils will react to the addition of lime or fertilizer and calculate how much of each is required for crop production.

Dust Control with Engineering Systems in Poultry Houses (C 1214) High levels of dust in cage-free poultry house air can carry airborne microorganisms and endotoxins that, once inhaled, may trigger respiratory diseases in animals and/or their caretakers. Mitigating dust levels is imperative to protecting the health and well-being of the animals and their caretakers and improving the environmental stewardship of cage-free layer farms. Studies have concluded that …

Evaluating and Interpreting Application Uniformity of Center Pivot Irrigation Systems (C 911) With rising fuel prices it is increasingly important that irrigation systems apply water uniformly in order to achieve maximum benefit from the water applied. The uniformity of water application under a center pivot is determined by setting out cans or rain gauges along the length of the pivot, bringing the irrigation system up to proper operating pressure, and letting the system pass over them.

Fences for Horses (B 1192) Fences are necessary to safely confine horses yet provide them with the opportunity to exercise and graze. Because of the natural flight response of horses, they tend to injure themselves in fences more than most other livestock. In addition, many horses are extremely valuable and that justifies the extra cost of building a fence that is safe, strong and attractive. When selecting a fence, conside…

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.

How to Grow Greenhouse Spinach During Georgia Summers Using Hydroponics (C 1304) Spinach (Spinacia oleracea) is an important nutrient-dense leafy green, and its annual per capita consumption has significantly increased over the past decades. Spinach production in Georgia has experienced significant growth in the last few years, with over $400M in annual value, ranked first among all the other leafy green crops. Field spinach production is labor intensive, and the cost of weed …

Hurricane and Storm Damage to Greenhouse and Greenhouse Crops (TP 120) Hurricanes can cause severe damage to greenhouse structures and crops, both directly and indirectly. Strong winds, heavy rains, and flooding not only impact physical infrastructure, but also damage crops through exposure to extreme conditions. Additionally, disruptions to water, electricity, and logistics complicate production efforts. This publication outlines common types of hurricane damage in…

Nozzle Selection for Sprayers Equipped with Pulse Width Modulation Technology (C 1305) Pulse width modulation (PWM) technology is becoming a standard option on most new agricultural sprayers because of its ability to precisely regulate both flow rate and pressure over a wide range of travel speeds. This publication provides information on nozzle selection for sprayers equipped with PWM technology, including how to use PWM nozzle selection/tabulation charts, other useful online tools…

Row Crop Planter Checklist: Tips to Achieve Successful Stand Establishment (C 1231) The lack of proper planter setup and maintenance results in common planting mistakes that affects crop stand and yield every year. Growers can easily avoid these mistakes by following a few simple steps at the beginning of the planting season to ensure proper planter setup for maximized field performance. This simple and easy-to-follow checklist provides tips on how to properly set up different pl…

Shallow Subsurface Drip Irrigation: A Tool for Organic Vegetable Growers (B 1564) This publication highlights some of the ongoing research into using SSDI in organic vegetable crop production. SSDI facilitates cultivation without harming drip tubing and limits surface soil wetting, which may also reduce weed pressure. Prior research has shown that SSDI offers some advantages over surface-placed drip tubing in conventionally grown crops (Coolong, 2016).

Spring Center Pivot and Lateral Irrigation System Preparation (B 1452) The main objective of this fact sheet is to provide a checklist of what is needed to properly prepare a center pivot or lateral irrigation system for the production season. All of the topics covered apply to both pivot and lateral irrigation systems, but for brevity, only center pivots will be referenced. By using the items in this fact sheet as a guideline for preventative maintenance, most break…

Winterizing Your Irrigation System (B 1439) Irrigation systems are used by farmers and homeowners to supply supplemental water to their crops. At the end of the growing season, the irrigation system should be checked and winterized to maintain proper operation for the coming season. This publication provides a list of suggested things that should by done on both drip and center pivot systems to help protect them during the winter months.
