Conclusion

The amount of leaf litter that would fall in one year was 18976.3g in clean soil and 1779g in dirty soil. Thus, there was obviously more leaves that fell in the clean soil than in the dirty soil. The mass of leaf litter in the clean soil which is 18976.3g was about 10.7times greater than the mass of leaf litter in dirty soil therefore in the clean soil there are much more materials decomposed and so that the clean soil is more dense than the dirty soil. This results in the lower permeability in the clean water and higher permeability in the dirty soil. 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).
