Evaluation of farmers" irrigation practices in El-Hammami sands
A study of the farms of the El-Hammami area in the El-Mansuriya region of Egypt"s Giza Governorate was carried out to evaluate three issues in the irrigation of sandy soils: (1) irrigation application efficiency at the farm level; (2) farmers" design criteria; and (3) water table contribution to water uptake by plants.

Abstract
The on-farm irrigation practices in the area indicated that the farmers at the beginning of the El-Hammami canal apply more water than do farmers at the tail end of the canal; the latter showed a higher rate of efficiency in irrigation application. The data also indicated that subsurface irrigation due to seepage from neighboring fields contributed substantially to crop water use. The study showed that surface irrigation might not be the best way to irrigate these sandy soils. Included in the report are 28 technical tables, 12 figures, and an 18-item bibliography (1955-82).
