Impact of Zeolite from Coal Fly Ash on Soil Hydrophysical Properties and Plant Growth

Zeolites can be extensively employed in agricultural activities because they improve soil properties such as infiltration rates, saturated hydraulic conductivity, water holding capacity, and cation exchange capacity. Natural synthetic zeolites efficiently hold water. are also believed to have the ability lose gain reversibly, without changing their crystal structure. In present study, several laboratory tests were carried out using: (i) zeolite synthesized from coal fly ash (a waste product burning thermoelectric power plants), (ii) a silty loam soil, typically found Southern Italy, (iii) sunflower reference plant. The selected was amended with different percentages of (1, 2, 5, 10%) effects mineral addition on hydrophysical plant growth evaluated. results indicated that soil–zeolite mixtures retained more by pore radius modification. However, this causes variation range plant-available towards higher humidity values, amount added increases. These data confirm modifies effect decreasing drainage making less habitable for growth.
