Drip and Microirrigation for Trees, Vines, and Row Crops (with Special Sections on Buried Drip)Irrigation Training and Research Center, Department of Agricultural Engineering, California Polytechnic State University, 1994 - Technology & Engineering - 261 pages This book contains previously unpublished & practical design & management information on all forms of drip & microirrigation for agricultural crops. This book benefits from over 30 years of drip/micro design & management experience by the authors in addition to information gleaned from dozens of recent visits to growers using the latest versions of drip/micro. This book is not a repeat or conglomeration of published research. It is meant to satisfy questions by students, designers, & growers who must make hard decisions in the field. Major sections deal with benefits & problems associated with various forms of buried drip. Complete design examples are given for 3 irrigation systems, & new design criteria are provided for pipe sizing of buried drip systems. This book is a must for anyone contemplating practical drip/micro design & management. To order, contact; Irrigation Training & Research Center, Cal Poly, San Luis Obispo, CA 93407; 805-756-2434. |
