  • Anticipating Drought on Rainfed Farms in the Southeast (B 1403)

    Nobody wants drought, but it’s been happening a lot in recent years in the Southeastern U.S. For farmers without irrigation, it may seem that little can be done besides accept what rain comes. However, by paying attention to forecasts and following general practices that help collect and retain moisture, risk can be reduced for all manner
    of future climate conditions. Here are some ideas for what can be done, centered around two practices: first, knowing what’s in store; second, planning ahead. Published on Aug 30, 2013.

  • Considerations for Subsurface Drip Irrigation Application in Humid and Sub-humid Areas (C 903)

    Subsurface drip irrigation is the practice of installing drip irrigation below the ground surface. This publication is designed to provide a brief introduction to the site selection, design, installation and management of subsurface drip irrigation. Published on Aug 30, 2013.

  • Drip Irrigation in Pecans (B 936)

    Research conducted on drip-irrigated pecans in Georgia over the past several years has shown that drip irrigation is highly beneficial even in wet years. The objective of drip irrigation is to supply each plant with sufficient soil moisture to meet transpiration demands. Drip irrigation offers unique agronomic, agrotechnical and economic advantages for the efficient use of water. Published on Aug 30, 2013.

  • 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. Published on Aug 30, 2013.

  • Factors to Consider in Selecting a Farm Irrigation System cover image Factors to Consider in Selecting a Farm Irrigation System (B 882)

    The majority of agricultural irrigation systems in Georgia fit into one of two broad categories: sprinkler irrigation and micro-irrigation. Sprinkler irrigation systems include center pivot, linear move, traveling gun, permanent set and solid set. Micro-irrigation systems include drip (or trickle) irrigation and micro-sprinklers.

    No one system is best for every application. Once you decide to install an irrigation system, you must consider several important factors before deciding which system is best for your situation. This publication is intended primarily for the farmer who has made the decision to irrigate and is in the process of deciding what type system will best fit into his or her operation. Published on Dec 30, 2015.

  • Irrigation Pumping Plants and Energy Use (B 837)

    Energy inputs for irrigation pumping frequently exceed the energy used for all other crop production practices. This fact, coupled with rapidly increasing fuel and energy costs, causes irrigation farmers to look for ways to reduce energy consumption. Careful consideration should be given to selecting a pump that will deliver water to the system with the greatest possible efficiency. After installation, pump performance should be watched closely and evaluated, with steps being taken as needed to adjust, repair or replace inefficient pumping equipment. Published on Aug 30, 2013.

  • Irrigation Scheduling Methods (B 974)

    To schedule irrigation for most efficient use of water and to optimize production, it is desirable to frequently determine the soil water conditions throughout the root zone of the crop being grown. A number of methods for doing this have been developed and used with varying degrees of success. In comparison to investment in irrigation equipment, these scheduling methods are relatively inexpensive. When properly used and coupled with grower experience, a scheduling method can improve the irrigator’s chances of success.This publication covers the working principles of currently used methods for scheduling irrigation. Published on Aug 30, 2013.

  • Irrigation Water Quality for Agriculture (B 1448)

    With growing demands for potable (suitable for drinking) water (due to population increase) and expanding irrigated acreage, there is an increased pressure on irrigated farms to consider using nonpotable alternatives. However, low quality irrigation water can adversely affect soil physical conditions and crop production.

    This publication provides in-depth information on the following aspects of agricultural irrigation water quality:
    -Importance of irrigation water quality
    -Major attributes of irrigation water quality
    -Common units used
    -Salts content

Two basic types of irrigation are suitable for the home landscape: sprinkler irrigation and drip (or trickle) irrigation. This publication contains comprehensive information about irrigating lawns and gardens. Published on Mar 31, 2014.

  • Spring Center Pivot and Lateral Irrigation System Preparation cover image Spring Center Pivot and Lateral Irrigation System Preparation (B 1452)

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 breakdowns during the growing season should be avoided. Published on Jul 31, 2016.

  • UGA EASY Pan Irrigation Scheduler (B 1201)

    The UGA EASY (Evaporation-based Accumulator for Sprinkler-enhanced Yield) Pan Irrigation Scheduler is designed to provide in-field monitoring of crop water needs in humid areas for a fraction of the management time and cost associated with other irrigation scheduling methods. If a farmer is not currently using a more sophisticated irrigation scheduling method, this unit is a simplified, low cost alternative. The UGA EASY Pan Irrigation Scheduler is designed to help you keep track of when your next application is needed, so you can avoid applying too much or too little water. The overall goal is to be more efficient in the use of irrigation water. Published on Aug 30, 2013.

  • UGA EASY Pan Irrigation Scheduler: Pan Size Considerations (B 1201-1)

    The University of Georgia EASY Pan (Evaporation-based Accumulator for Sprinkler-enhanced Yield) was introduced in 2001 as a simple, cost-effective alternative for scheduling irrigations on sprinkler irrigated row crops in humid regions. Several users have questioned the need for the larger sized tub or pan. This publication presents results of a test with two smaller pans. The potential to use a smaller unit would allow a single individual to easily set up and maintain the EASY Pan and, at the same time, reduce the overall cost of materials in the construction process. The hypothesis of this particular test was that the two smaller pans would respond in a similar manner to the larger pans under evaporation and excess rainfall conditions. Published on Aug 30, 2013.

  • 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. Published on Jan 30, 2015.
