Micro irrigation, also known as trickle, drip, localized, high frequency, or pressurized irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant. Clogging is a menace in the success of drip irrigation systems, and the situation is more complex under subsurface drip irrigation. Irrigation planners and engineers have found a variety of innovative methods to help to minimize clogging.
This book emphasizes the implications of micro irrigation clogging, especially under the subsurface placement of laterals. The book offers remedies to decrease clogging and methodologies to improve the performance of micro sprinklers. This valuable resource addresses this critical problem, covering:
- Challenges in clogging under subsurface drip irrigation
- Principles, practices, and management of emitter clogging
- Efficiency of acidification for unclogging of emitters
- Performance characteristics of micro sprinklers
The book will serve as a reference manual for professionals in biological and civil engineering, horticulture, soil and crop science, and agronomy, as well as for graduate and undergraduate students in related fields. It will be a valuable reference for professionals who work with micro irrigation/wastewater and water management and for technical agricultural centers, irrigation centers, agricultural extension services, and other agencies that work with micro irrigation programs.

"I congratulate the editors on the completion and publication of this book volume under the series on Innovations and Challenges in Micro Irrigation. Water for food production is clearly one of the grand challenges of the twenty-first century. Hopefully this book series will help irrigators and famers around the world to increase the adoption of water savings technology such as micro irrigation."
—Vincent F. Bralts, PhD, PE, Professor and Former Associate Dean, Agricultural and Biological Engineering Department, Purdue University, West Lafayette, Indiana
"Informative and is a must for all irrigation planners to minimize the problem of water scarcity worldwide. The Father of Irrigation Engineering in Puerto Rico of the twentieth century and pioneer on micro irrigation in Latin America, Dr. Goyal [my longtime colleague] has done an extraordinary job in the presentation of this book volume."
—Miguel A Muñoz, PhD, Former President of University of Puerto Rico, and Professor/Soil Scientist
