Agriculture
Globally, the agricultural sector consumes about 70% of the planet’s accessible freshwater. Because water is vital for the success of agriculture, proper water management techniques are necessary to meet food and fiber material demands around the world. Resources available here pay special attention to efficient irrigation and sustainable agriculture techniques.

Institutional Framework for Improved on - Farm Water Management in Pakistan
Published:
January 1, 1976U.S. Agency for International Development, Colorado State University
Sufficient data has been collected and analyzed to define some of the major irrigation water management problems in Pakistan, as well as the technologies that could be employed to correct many of these problems. Thus, there is a strong basis for undertaking a program of improved on-farm water...Read more

Published:
March 1, 1974U.S. Agency for International Development
The following areas of knowledge deficiency in the field of on-farm water management were identified by the Symposium: (1) Physiological responses of crops to environmental stresses, (2) optimal crop productivity relationships of water and other inputs; (3) methods for systematically transferring...Read more
Program for Computing Equilibrium Solution Composition in Caco (,3) and Caso (,4) Systems from Irrigation Water Compositions
Published:
October 1, 1973U.S. Agency for International Development, Colorado State University
A computer program was developed to calculate equilibrium solution compositions in calcareous and gypsiferous systems. The calculations in the program are based upon published solubility products of calcite and gypsum and take into account ion-pair formation and the solubility enhancement of...Read more
Trickle Irrigation Soil Water Potential as Influenced By Management of Highly Saline Water
Published:
July 19, 1973U.S. Agency for International Development
Although trickle irrigation offers the possibility of obtaining comparatively good yields when nontoxic highly saline water is used for irrigation, the subsequent accumulation of salts in the root zone is a potential hazard that should not be disregarded. The objective of this investigation was to...Read more
Plan for a Surface Irrigation System for the Taboga Exp. Station, Costa Rica
Published:
April 1, 1973U.S. Agency for International Development
This report is based on a brief trip to Costa Rica by J.E. Christiansen and Rex F. Nielson to provide technical assistance in the planning of an irrigation and drainage system for the Taboga Experimental Station in the Province of Guanacaste. A three-day visit was made to the area, and shorter...Read more

Brazil, Latin America and the CaribbeanEconomic Aspects of Irrigation from Ground Water
Published:
January 1, 1972U.S. Agency for International Development
Typical examples of economic analysis of ground water development in Brazil are discussed, citing specific data for Bolivian conditions with conversion to Cruzeiro values, but without a detailed knowledge of commodity prices and costs in Brazil. Use of ground water can produce both irrigation and...Read more

Latin America and the CaribbeanIrrigation Requirements for Turf
Published:
January 1, 1972U.S. Agency for International Development
There is much over irrigation of turf. Some is unavoidable but significant savings of water can be had from a better understanding of the principles of scheduling irrigation. Irrigation scheduling is greatly facilitated by uniformity of soil depth and moisture storage capacity. This paper describes...Read more
