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 contains step-by-step guidelines for determining irrigated acreage of stationary sprinkler irrigation systems.
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.
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.
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 field calibration of hard hose and cable tow irrigation systems. Proper calibration is required by law.
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.
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.
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.
