runoff generation and soil loss control using combined application of vermicompost and vinasse
نویسندگان
چکیده
application of additives on soil surface has been considered to control runoff and soil erosion as well as the necessity of recycling. however, application of the environmentally-friendly techniques has been less taken into consideration. hence, the present study was planned to determine the effect of combination of vermicompost (24 g) with sugarcane vinasse (22 cm3) on runoff and soil loss at plot scale for an erosion prone soil from southwest of mazandaran province, iran. the comparison was made with control and individually treated plots. in this study, three small plots of 0.5 × 0.5 × 0.3 m with a slope of 30% in three treatments statistical design and three completely random repetitions were used. to conduct the study, a rainfall with intensity of 80 mm h-1 and duration of 8 min was simulated after 48 h from saturation time to apply treatments and combined application of vermicompost and vinasse. ultimately, runoff and sediment were sampled. the results of the statistical analysis verified a significant effect (p=0.009) of combined application of vermicompost and vinasse on soil loss. whereas, the reducing effect of similar treatment and the necessity of water recycling was found non-significant (p=0.295) in controlling runoff from the plots

Soil erosion is a global challenge, seriously threatening soil and water resources andenvironmental qualities. One of the important factors to consider in the process of runoffgeneration and soil erosion is the physical and chemical properties of soils under differentland-uses. The aim of this study is to estimate soil erosion and runoff in rangeland, rain-fedand abandoned rain-fed agriculture ...

ABSTRACT- In recent years, intensive drought has caused a severe yield reduction in rain-fed trees. Increasing runoff of low amount rainfall can be used to provide partial water requirement of rain-fed trees. To achieve this objective, some strategies including gravel removal (G), rill construction across to slope (R) and applying of baking soda (S) and their effects on runoff, rainfall infiltr...

Application of Gully and Rill Erosion Indicators for Estimating Soil Loss Using GIS Techniques
The problems of land degradation and soil loss are among the major problems of watersheds in Iran. For erosion andsediment estimation one can use statistical and empirical methods. For doing this, land unit map and the map of effectivefactors should be prepared. For erosion and sediment estimation one can use statistical and empirical methods. However,these empirical methods are usually time co...
