cm depth intervals 1 .
1 Soil texture data for the 40-60 cm and 60-80 cm were obtained from Soil Conservation Service
[12]. All other data were measured during the project.
14.3 RESULTS AND DISCUSSION
The Coto clay soil was analyzed for various physical and hydraulic properties (Table
1). The soil has a relatively high sand content and high hydraulic conductivity in the
0-20 cm interval, which accounts for it high water intake capacity. We observed on
