The Effects of Tobacco Wastes (Unmixed and Mixed) on Some Erosion Parameters and Chemical Properties of A Loamy Textured Soil

23242

To reduce soil loss by erosion has been applied organic materials in soils are important. In this study, a loamy soil sample passed through from 8 mm sieve was placed into erosion plots which have a drain pipe and sized as 30x45x15 cm and 0, 10, 20 and 40 t/ha doses of tobacco wastes as unmixed and mixed on soil surface were given on erosion plot. 30, 60 and 90 mm/h of rainfall intensities were applied on these plots during 1 hour. Soil reaction (pH) and electrical conductivity (EC) values of experimental soils and drained waters were determined. Runoff, soil loss and drained water taken from experiment were calculated. According to the study results, unmixed applied tobacco wastes on soils were decreased runoff by 39-94%, and soil loses by 96-100, whereas increased drainage by 1-11 times, compared with controls. The mixed applied tobacco waste on soils was decreased runoff by 10-65%, and soil loses by 35-90%, whereas increased drainage 0.7-4 times compared with controls. Tobacco waste was decreased soil reaction (pH) significantly, whereas increased soil conductivity (EC) significantly. It was found that surface applied tobacco waste was more effective than mixed applied tobacco waste on reducing runoff and soil loss, and increasing drainage
