1979Also available in:
No results found.The pressing need for increased agricultural production in the years ahead can only be met by more efficient use of our land and water resources including more widespread and better irrigation in those regions where rainfall is inadequate. Production gains will be shortlived unless the attendant hazards of salinization, water logging and lowered fertility are kept in check by effective planning and management based on a thorough understanding of the soil conditions. Soil survey and land classifi cation are generally accepted essential preliminaries to investment in irrigation development. This publication aims to describe the special requirements of soil survey for irrigation development, and assumes that the reader is familiar with basic soil science and soil survey techniques. -

Also available in:
No results found.This is one in a series of training manuals on subjects related to Irrigation that will be issued in 1985, 1986 and 1987. The papers are intended for use by field assistants in agricultural extension services and irrigation technicians at the village and district levels who want to increase their ability to deal with farm-level irrigation issues. Irrigation water needs is the third in a series of training manuals on irrigation. Unlike Volumes 1 and 2, Volume 3 has been divided into two parts. The papers contain material that is intended to provide support for irrigation training courses and to facilitate their conduct. Thus, taken together, they do not present a complete course in themselves, but instructors may find it helpful to use those papers or sections that are relevant to the specific irrigation conditions under discussion. The material may also be useful Co individual students who want to review a particular subject without a teacher.
