Sustainable micro irrigation principles and practices
Sustainable Micro Irrigation: Principles and Practices by Megh R. GoyalThis new book, Principles and Practices of Sustainable Micro Irrigation, is the first in the new series on micro irrigation, which offers a vast amount of knowledge and techniques necessary to develop and manage a drip/trickle or micro irrigation system. Written by experienced scientists from various parts of the world, the chapters in this book offer basic principles, knowledge, and techniques of micro irrigation management, which are essential in designing, developing, and evaluating an agricultural irrigation management system. The methods and techniques have worldwide applicability to irrigation management in agriculture.
The book includes coverage of many important topics in the field, including:
An historical review of micro irrigation
The current global status of the field and its potential
Basic principles and applications
New research on chemigation and fertigation
Technologies for specific crops, such as sugar cane
Irrigation software for micro irrigation design
Affordable and low-cost micro irrigation solutions for small farms and farms in developing countries
Micro irrigation design using Hydrocalc software
This book is a must for those interested in irrigation planning and management, namely, researchers, scientists, educators, and students.

Research Advances in Sustainable Micro Irrigation
Sustainability of Irrigated Agriculture pp Cite as. Drip and minisprinkler irrigation systems have experienced an enormous increase in commercial significance and research interest in the past three decades. Both systems as they are known today became practical with the development of plastics that were inexpensive, durable, and easily moulded into the variety and complexity of shapes required for pipe and emitters. The earliest systems were made up of small-bore 1—2 mm ID plastic microtubes emitters inserted into larger-diameter plastic pipe. Water emission rate was controlled by friction in the microtube, producing irrigation rates of 2 to 6 litres per hour per emitter. Operating pressures were low, often around kPa, necessitating careful system design to offset effects of small elevational changes on internal system pressure and emission rate.

About the Series
Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation. Drip irrigation systems distribute water through a network of valves , pipes , tubing , and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation. Primitive drip irrigation has been used since ancient times. Fan Shengzhi shu , written in China during the first century BCE , describes the use of buried, unglazed clay pots filled with water, sometimes referred to as Ollas , as a means of irrigation. Modern drip irrigation began its development in Germany in when researchers began experimenting with subsurface irrigation using clay pipe to create combination irrigation and drainage systems.
