This publication provides information you will need for measuring soil water: types of soil-water measuring devices, how to select the right measuring device and how to prepare and install these devices.
The center pivot and linear-move type irrigation systems are usually the most practical system for irrigating large, rectangular or regular shaped fields. Selection and management considerations for center pivot and linear-move type systems are discussed in this article.
This publication provides background information and references for the Water Needs Assessment Tool spreadsheet and its data inputs. It also discusses the methods used to generate output from the model and provides examples.
This publication discusses how to ensure efficient supplemental water management to maintain turfgrass growth by evaluating irrigation system performance. Completing an audit of an irrigation system provides the information needed to set irrigation controllers to deliver the proper amount of water.
Hand-move irrigation systems are normally used to irrigate small fields. Solid-set and permanent sprinkler irrigation systems are used for irrigation, frost/freeze protection, evaporative cooling, and land application of nutrient-rich effluent. Selection and management considerations for hand-move solid-set and permanent sprinkler irrigation systems are discussed in this article.
As a part of the humid Southeast, North Carolina’s climate, topography, soils, cropping systems, and water sources require special consideration when considering and implementing a subsurface drip irrigation (SDI) system. This publication is not a step-by-step design manual, but it will help you in the design process of an SDI system appropriate to North Carolina.
The self-propelled gun type traveler system is usually the most practical system for irrigating irregular shaped fields. Selection and management considerations for self-propelled gun type systems are discussed in this article.
Low volume irrigation systems are normally used for fruits, vegetables, container nursery plants and in the landscape. For all these uses, growers are interested in highly controlled water management systems. Selection and management considerations for low volume irrigation systems are discussed in this article.
This publication contains step-by-step guidelines for determining irrigated acreage of stationary sprinkler irrigation systems.
This publication explains how to plan and maintain subirrigation systems by providing information on types of water supplies and pumps and water quality.
This publication contains step-by-step guidelines for determining irrigated acreage for hard hose traveler irrigation systems are presented. Proper calibration helps protect the environment and is required by law.
This publication explains calibration procedures for stationary and hard-hose traveler irrigation systems and how to determine acceptable application uniformity for the systems as established by the ninth and latest edition of the SB 1217 document (North Carolina 1217 Interagency Group, 2009). It does not invalidate the procedures (commonly referred to as the “catch can” method) described in AG-553-1 and AG-553-2 if operators want to use those for uniformity assessment. However, AG 553-1 and AG 553-2 do not fulfill the flow measurement calibration requirements currently established by the ninth edition of the SB 1217 document.
This publication provides guidelines and recommendations for proper irrigation scheduling of wastewater.
This publication contains step-by-step guidelines for field calibration of hard hose and cable tow irrigation systems. Proper calibration is required by law.
Although subsurface drip irrigation (SDI) is in its infancy in North Carolina, it is becoming more popular as growers learn of its many benefits, which include increased irrigation efficiency. Proper management is imperative with an SDI system. Many components of an SDI system are underground; therefore, you must carefully monitor pressure and flow rates to ensure that the system is operating properly. This publication addresses water management, chemigation, system management and maintenance, and system evaluation.
