Demonstration Of Humus Formation From Sand Substrate

I found this a really interesting video showing how bacteria and fungi, along with the rest of those little critters from the soil food web work together to create humus (soil/compost) from just a sand substrate. This captures the process over a one year period in a time-lapse video showing the formation of algae and moss on top of the inoculant and then seeding it to create plants, as the process develops it results in the creation of a soil layer. It also details the process she went through to get to this point and at the end shows us some microscopy sequences of the organisms in this soil food web. There is also another video below which briefly shows a little more details. Seeing this makes me want a microscope even more now.

Lets Stop Desertification By Planting Forests

The above is a clip from “Greening the Desert” with Geoff Lawton, located in Jordan.

Documentary about turning around and regaining land lost to desertification. Geoff helps turn a baron desert into a thriving forest. He talks us through the process of transforming the desert ground via processes that included things like desalination (desalting soil), water retention via swales, heavy mulching, planting legumes and many other things and they basically end up building top soil and in turn fertility.
This is the full documentary on the subject by Geoff: http://www.youtube.com/watch?v=xzTHjlueqFI

Also check out this Dutch Documentary “Green Gold” about a guy called John Liu who documented the Chinese rehabilitating large scale damaged eco systems (the size of the Netherlands), effectively stopping desertification:
