Rate at which water passes through clean soil Rate at which water passes through dirty soil 0-10cm 77.9ml/min 81.6ml/min 10-20cm 32.0ml/min 170ml/min 20-30cm 0.1ml/min 34.2ml/min Calculation Rate= Amount of water passes though the soil / time taken 387.5g/5 min=77.9g/min Distance from the surface of the soil Rate at which water passes through the clean soil Rate at which water passes through the dirty soil 0-10 77.9ml/min 81.6ml/min 10-20 32.0ml/min 170ml/min 20-30 0.1ml/min 34.2ml/min Conclusion The amount of leaf litter that would fall in one year was 18976.3g in clean soil and 1779g in dirty soil. ...read more.

Conclusion

The rate at which water passes through each soil which indicates the permeability of each soil was 77.9ml/min in clean soil and 81.6ml/min in dirty soil with top (surface) soil, 32.0ml/min in clean and 179ml/min in dirty soil with soil of 10-20cm depth and 0.1ml/min in clean soil and 34.2ml/min in dirty soil with soil of 23-30cm depth. Overall rate, permeability, in dirty soil was greater than one in clean water and as I mentioned before I think that is because of the density of the soil. And in each soil the permeability tends to decrease as the soil gets away from the surface (as it gets deeper). ...read more.
