Effects of organic conditioner applications on soil loss under simulated rainfall conditioner

34006

This study was conducted to determine effects of farmyard manure, rice husk and municipal waste compost on soil loss caused by runoff in two different soil groups under greenhouse conditions. Soils used in the study were classified as Lithic Ustorthent and Typic Calciustept located in Minöz Basin of Samsun province. Organic conditioners were applied to the soils of basin according to dry weight basis at four different doses (0, 2, 4 and 6 %) under greenhouse conditions. Experiment was planned in a randomized factorial plot design with two replications. After a 12-week incubation period, 15 % slope was given to erosion pans and 55 mm h -1 and 70 mm h-1 artificial rainfall intensities were applied for one hour and soil loss values caused by runoff were measured. At the end of the experiment, it was determined that organic conditioners applied to the soils reduced soil losses. Municipal waste compost was determined to be more effective than rice husk compost and farmyard manure in reducing soil losses occurred in runoff pans. Effectiveness of organic conditioners showed differences depend on application doses and the lowest soil loss in each obtained at the maximum dose. The results suggest that using organic conditioners in the agricultural fields reduces soil degradation and loss.
