Microirrigation has become the fastest growing segment of the irrigation industry worldwide and has the potential to increase the quality of food supply through improved water fertilizer efficiency. This book is meant to update the text "Trickle Irrigation, Design, Operation and Management". This text offers the most current understanding of the management criteria needed to obtain maximum water and fertilization efficiency.
- Presents a detailed explanation of system design, operation, and management specific to various types of MI systems
- Analyzes proper use of irrigation technology and its effect to increase efficiency
- Provides an understanding to the basic science needed to comprehend operation and management
- Over 150 figures of designs and charts of systems including, surface drip, subsurface drip, spray/microsprinkler, and more
