On three of the four distributary canals studied by EWUP, the soils were mostly alluvial clay soil (vertisols) or a vertic subgroup of the entisols. The remaining distributary canal was all sandy Entisols. Vertisols are as oil order composed of heavy, clay soils containing large quantities of clay minerals which expand when wet and contract when dry. Irrigating these soils requires recognizing that the root penetration and measurable soil water changes are restricted to the top 40 cm. This limits the operational available water to 5 to 7 cm. The water infiltration rate during an irrigation can have a hundred fold decline during a 2 hour irrigation, ending with almost sealed conditions. This allows highly uniform application over a large area almost independent of available flow rate. Soil sealing requires a potential for surface drainage to prevent crop suffocation. After an irrigation, redistribution tends to be very slow, with the possibility in winter of it requiring 15 days for a wetting fringe to drain 30 cm. The high infiltration rates in the sandy soils make them basically unsuited for surface irrigation. It is therefore difficult to surface irrigate them efficiently. High water tables occur with large volumes of subsurface water flow. A de facto sub-irrigation system results in which farmers applying water to their field sub-irrigate their neighbors and vise-versa. Some farmers, far from the water source, actually receive more water than their crops required.

(Location: IWMI-HQ Call no: 631.4 G232 NAI Record No: H043)
This report is a summary of a series of studies on zinc status in thesoils of the project sites, Kafr El-Sheikh, El-Mansuriya, and El- Minya, during the agricultural years 1978/79 and 1980/81. The studies included a soil fertility survey and on-farm tests for various crops. The results indicate that: (1) there is a wide range in available soil zinc within the different Project areas, and a crop response to added zinc fertilizer would be expected; and(2) response to zinc differed from one crop to another and from replicate to replicate. The crops tested were wheat, broad beans, cotton, corn, flax and rice.
