Irrigation & Drainage

Care and Maintenance of Irrigation Wells

Effective irrigation is not possible without a reliable water source. In North Dakota, the availability of relatively shallow aquifers with high-quality water has spurred the development of irrigation in many areas. Irrigation wells must produce a high volume of water during the driest months: July and August. To maintain consistent, high production from year to year, a well requires annual maintenance, just like any other piece of valuable equipment.

Compatibility of North Dakota Soils for Irrigation

This publication is intended as a first step to help current and prospective irrigators understand the principles behind the irrigability of soils in North Dakota. This publication lists all the soils in the state with relevant properties and categorizes them as irrigable, conditional or nonirrigable.

Irrigation Water Pumps

A pump is the heart of most irrigation systems and if not maintained can use much more power than required leading to excess pumping costs and wasting electricity.

Irrigation Water Sample Analysis

The NDSU Soil and Water Testing Laboratory has been making soil-water compatibility recommendations since the early 1960s. These recommendations are based on the electrical conductivity (EC) and sodium adsorption ratio (SAR) determined on the irrigation water and the soil series present on the land to be irrigated.

Managing Saline Soils in North Dakota

Saline soils contain salts in great enough abundance that crop yields suffer and sometimes makes successful crop production impossible. This publication talks about testing your soil, salinity management, mapping, crop selection and tile drainage.

Selecting a Sprinkler Irrigation System

The four basic methods of irrigation are: subsurface irrigation (“subirrigation,” which uses tile drain lines), surface or gravity irrigation, trickle irrigation (also called drip irrigation) and sprinkler irrigation. Of the acres currently irrigated in North Dakota, more than 80 percent use some type of sprinkler

Tile Drainage Pump Stations for Farm Fields

Drainage pump stations are an expensive addition to a subsurface drainage project. This publication provides guidance on the design and location of drainage lift stations. This topic an be difficult to teach in typical Extension presentations, this publication provides more details.
