Monitoring for Moisture for Irrigation Water Management; ANR Pub. 21635 

Monitoring soil moisture is an alternate method to water-based balance methods of managing irrigation water. Using this method you can “see” what is going on in the soil and determine answers to some key irrigation management questions.

•Did enough water infiltrate the soil?
•Is too much water being applied?
•What is the water uptake pattern of the roots?
•When should irrigation take place?
•What was the depth reached by the irrigation?

Includes 24 figures and 7 tables, metric conversions, and an appendix of typical root depths.

Maintaining Microirrigation Systems;  ANR Pub 21637 

This handy publication discusses the maintenance issues of microirrigation systems that can be used on tree crops, row crops, and trees and vines.

Chapters include an overview of maintenance needs, monitoring and water assessment, causes and prevention of clogging, flushing and safety concerns. Also includes methods of preventing root intrusion, soil ingestion, bacterial growth, and backflow contamination.

2009 winner of a “Blue Ribbon” award for excellence in educational publications from the American Society of Agricultural and Biological Engineers.
