soil
properties of the experimental field are given in Table 1.
Soil moisture content was gravimetrically determined on an oven
dry basis. At each sampling date, duplicate soil samples were
taken to a depth of 60 cm using an auger. The samples were
immediately transferred in tightly closed aluminum cans to the
laboratory where they were weighted, oven-dried at 105°C for 24h,
and reweighed after which their moisture content was determined.
Field capacity and permanent wilting percentage were determined.
The bulk density was determined using the core method to a depth
of 60 cm (Klute, 1986). The results are presented in Table 2.
The soil was clayey in texture, whereas particle size distribution
was 56.1% clay, 31.30% silt, and 12.60% sand. Soil pH (1:2.5) was
8.3, and electrical conductivity of soil and irrigation water was 2.00.
