2. Zeolite «Clinoptilolite»
-(Na,K,Ca)2-3Al3(Al,Si)2Si13O36·12(H2O)
Hydrated aluminosilicates
Characterized by three-dimensional networks of SiO4 and AlO4 tetrahedra
High cation exchange capacity
High surface adsorbtion capability
I would like to describe zeolite first. Due to it is great physical properties, it is generally used for amelioration of soils. But it is also can be used to conditioning water regime of soils with its porous structure. We studied its effects on potassium capacity.

3. 1. Material Sandy soils from Menemen Region
Two different clinoptilolite type of zeolite with equivelent diameter of <200µ and 3-4 mm.
Soil taken from menemen has alcaline reaction. Ph between There were no sodicity or salinity problem.
As you can see in the image lots of commercial products of zeolite cen be produced with different size of diameter. In this study we choose coarse and thin zeolite.

4. 1.1. Some Important Properties of Clinoptilolite
pH:
CaO: 2%
K2O: 3%
Na2O: 0.2%
Porosity: 35-40%
Coarse Zeolite(CZ): 3-4 mm
Thin Zeolite(TZ): <200µ

5. 2.Methods
Study was carried out by randomized blocks experimental design in pots.
Z0: No zeolite application.
TZ1: 50 kg/da thin zeolite application.
TZ2: 100 kg/da thin zeolite application.
TZ3: 200 kg/da thin zeolite application.
TZ4: 400 kg/da thin zeolite application.
CZ1: 50 kg/da coarse zeolite application.
CZ2: 100 kg/da coarse zeolite application.
CZ3: 200 kg/da coarse zeolite application.
CZ4: 400 kg/da coarse zeolite application.
Experiment was conducted in 72 pots with 1kg of sandy soil.

6. Experiment was conducted in 72 pots with 1 kg of sandy soil.
Vegetation temperature was determined as 20 oC.
Vegetation period was determined as 40 days.
Each pot had 3 Quadro Corn plant.
After 40 days, plants were harvested and each plant with soil in pots were prepared for analyses.

7. Available K concentrations of soils were determined according to 1 N (pH: 7) Ammonium Acetat Method by flame photometry spectroscopy (Chapman, 1965).
Total K concentrations of plants were determined by AAS after wet digestion. (HNO3:HClO4 3/1; Baker and Smith, 1974)

10. Evaluation of Thin Zeolite Application by Percantage

11. Evaluation of Coarse Zeolite Application by Percantage
There is not a stabil increasing pattern at percantage. This can be related with absence of colloidal particals due to applying zeolite diameter of 3-4 mm.

13. General Evaluation by Percentage

14. Highest available potassium concentration of soils was achieved as 375
Highest available potassium concentration of soils was achieved as ppm by 400 kg/da zeolite addition while the control was ppm with regards to general statistical evaluation.
Highest total potassium concentration of plants was achieved as 5057,4 ppm while the control was ppm with regards to general statistical evaluation.
Concentrations of soils and plants also increased more with coarse zeolite additions than thin zeolite additions by a difference of 8.9% for soils and 6% for plants.
