Irrigation system walk-through inspection analysis

Creator:: Hansen, Hugh J., Trimmer, Walter L., Oregon State University. Extension Service, Washington State University. Cooperative Extension, University of Idaho. Cooperative Extension, and Pacific Northwest Cooperative Extension
Abstract:: This “walk-through” worksheet provides a method for making an organized inspection of an entire irrigation system, both hydraulics and hardware. This inspection will help identify components that need maintenance, repair, replacement, or other attention—so that the system will provide the most satisfactory, safe, and efficient performance.

Irrigation scheduling

Creator:: Trimmer, Walter L., Hansen, Hugh J., Oregon State University. Extension Service, Washington State University. Cooperative Extension, University of Idaho. Cooperative Extension Service, and United States. Department of Agriculture
Abstract:: The main purpose for irrigating is to supply needed water for crops. Plant growth is dependent on photosynthesis. While the plant exchanges gases with the air for photosynthesis, some water evaporates. Water is taken up from the soil by plant roots to replace this water. The water leaving the plant...

A computer model to simulate farm irrigation system energy requirements

Creator:: Kizer, Michael A.
Abstract:: The development of the energy crisis has caused the use of depletable energy resources to be monitored quite closely in the United States. Within the agricultural sector, irrigation is a large user of energy, with the potential of using many times more energy than all other agricultural field operations. A...

Orchard Irrigation

Creator:: Schrack, Claud and Currin, Harvey William
Abstract:: Irrigation should be recognized as agricultural art of very wide applicability and value. Its association with the idea of desert reclamation has blinded the public mind to its value in reginos where there is no need of reclamation.
