Investigation of Nanozeolite Effects on Soil Erosion Decreasing using FEL3 Rainfall Simulator

One of the most important problems in the world is soil erosion that threats the natural resource and it numerates as an important troublesome in environmental and agricultural aspects. In order to obtain these goals it is inevitable to use new techniques such as nanotechnology. Nanotechnology is one of the modern technologies that because of its high potential and particular characteristics، it has extensive application in all aspects of science such as natural resources and soil conservation. This study has been done in order to assess the effects of different percentages of Nanozeolite (0، 0. 2، 0. 4 and 0. 6 gram per square meter) on malry soils in several slopes degree (7، 9 and 14 degree) using FEL3 rainfall simulator. The plot had 50 centimeter width، 100 cm length and 40 cm height that 30 cm of height was used for drainage and 10 cm of height was used by especial soil texture. After adding Nanozeolite to soil surface، the samples were influenced by 90 millimeters per hour rainfall intensity during 30 minutes. Results show that the all of the Nanozeolite levels (0، 0. 2، 0. 4 and 0. 6) in the three levels of steepness (7، 9 and 14 degrees) had not significant differences in decreasing of soil erosion in comparison of control treatment.
