Investigation of soil water content changes with time and influence of natural zeolite of Clinoptilolite on it in sandy loam soil

Zeolite is a relative abounded mineral resource. Its distinguished properties on cation exchange capacity (CEC), free structural water storage and surface adsorption have a great potential application on soil ameliorating. In order to investigate the soil moisture changes with time and also the influence of zeolite in retentions of moisture in the loam sandy soil, we have designed a completely randomized plan in 5 treatments and 3 repetitions; totally we have had 15 pots. we have prepared all the pots and then we have mixed 1.5 kg soil with zeolite at ratios of 0, 0.2, 0.4, 0.8 and 5 percent weight of the soil. Treatments and different levels of zeolite consumption have nominated as (z0, z1, z2, z3, z4, z5). We have concluded that Z3 treatment has caused to increase the percent of moisture in the field capacity2.47%. The amounts of increases for Z1 and Z2 treatments were 1.83 and 1.86 percent. The results have shown that there was not a significant difference between treatments on the last days of experiment.
