Another thing about bare soil in the real word is, once it has become bare and baked dry by the sun, it tends to stay that way. The damage is long lasting. I have watched a small area in my pasture which had become worn down to bare soil by cattle traffic and little rain go from grass to dry powder and stay that way for 2 years now even though the traffic has ceased. Natural recovery is very slow and easily cancelled out.

Abraham I agree this video deserves more hits! Not sure why I didn't comment earlier but I've been showing this video to friends and even linked from my site :)

Me & my friend have to do a science experiment, & it has to do with water!
Do you have any ideas for it?
& by the way, you video was cool & fasinating!
Good Job!

Outstanding !! I just wonder why there are so few hits, I will most definitely replicate your experiment, but with soils with different OM content, it's vital that land managers comprehend that we need more carbon in our soils. Congratulations

brilliant..
this is what I need for my demonstration in Environmental Science

Thanks Abraham. One warning I would offer: this experiment does not show a big difference if you use soils with low hydraulic conductivity (that don't absorb water well), such as many soils high in clay.
The physics are simple: the biomass (litter) slows the flow of water across the surface, which allows more time for infiltration into the soil. In real-world conditions, the effect of litter is even greater, as it keeps soil cooler, and feeds and shelters microbes from the elements.
