چکیده:

There are plenty of lands with low soil texture that are not fertility in Iran. As we know there is an
increase in population and therefore we need to improve the yield production of agriculture plants. Zeolites
are minerals that are derived from mines and they have a wide usage in agriculture. We have designed a
completely randomized plan with four treatments to consider the impact of zeolite on CEC and PH of the soil
sample. So we mixed 1.5 kg of soil with different quantities of zeolite (Z0, Z1, Z2, Z3) in ratios 0, 0.2, 0.4 and
0.8 percent of weight and then we have filled pots with these mixtures. we have concluded that with increase
of zeolite, the CEC also increases. The insignificant of exchangeable sodium in different levels have shown
that zeolite does not have sodium. As it is shown in table.1 there is an increase of exchangeable potassium
with increase of zeolite quantity. And there is a significant difference in all levels zeolite consumption.
