The changes in water holding capacity of soil in respect to the different
treatments as show in Figure (1) revealed that no significant changes with
treatments T2, T3 and T6 as compared with control. But the other applicable
treatments were high significant increasing in water holding capacity.
Data illustrated in Figure (2), showed that, treatments T2, T3, T6 and T13
confirmed similar contents of soil capillary water as in control. Meanwhile, all
other treatments revealed significant difference in soil capillary water especially
with T5 and T7 which exhibit high significant difference as compared with
control.
Table (1) showed contents of the gravitational water of the tested soil
samples. The data revealed that the maximum value of gravitational water (86.33
ml / 100 ml water passing through 20 g soil) was reported in soils with T15 which
revealed a significant difference as compared with control and other treatments.
