Irrigation Guide

Picture of an Irrigation System The purpose of this Irrigation Guide is to provide irrigation information to be used by the Natural Resources Conservation Service (NRCS) employees in both the planning of farm irrigation systems and the planning and application of on-farm irrigation systems and the planning and application of on-farm irrigation water management.

The Irrigation Guide is an important part of basic resource data analysis and therefore is, by reference, a recognized part of the field office technical guide.

The information in this guide is to supplement national guidelines and has been tailored to reflect the special needs of New Mexico.

In an effort to give employees the best data available, and at the same time to keep abreast of new developments in irrigation technology, this guide has been developed with the following major sections:
