Abstract

Given that, a lot of soil lost from watershed area by erosion factors. The application of management methods is necessary for soil loss control. Therefore, the use of the available, economical and environmentally friendly conditioners can be the suitable approach in soil loss and runoff control. On the other hand, the soil and water conservation need to the suitable amount determination of soil conditioners to be in addition to reducing costs, from water contaminants prevented with application of chemical fertilizers. However, the optimum amount determination of soil various conditioners with quantifying aim of this effect less attended on runoff and soil loss components. Accordingly, in this study, the effect of various amounts of manure compost with rates of 2. 25, 4. 5, 9. 0 and 18. 0 t ha-1 on amount of runoff and soil loss from experimental plot with area of 0. 5 m 2, slope of 20 percent, was conducted using rainfall intensity of 50 mm -1 ha for duration of 10 min in agricultural soil that it collected from Sari province in year 2018. The results of statistical analysis indicated on the significant effect of various amounts of manure compost on changes of increasing time to runoff and decreasing runoff volume and coefficient, soil loss and sediment concentration in level of 99 percent. Also, the study of conservation effect and grouping various amount of manure compost showed that the compost with rate of 9. 0 t ha-1 for the same effect with amount of 18. 0 t ha-1 on changing sediment concentration can suggest as the optimum and practical amount in natural conditions.
