This material gives you a brief overview about the basics of soil knowledge out of the view of a
practicing organic and biodynamic farmer. Important ideas and theories are roughly described to
give the reader an idea on how to work with soil.

Soil seems to be a very interesting substance: It is a complex mixture of minerals, air, water, and
living organisms that we can find on the surface of all land areas. Soil is the tiny skin of earth.
Can you imagine how thin it is? Some experts say it is in relation 10 times thinner than the film
of an inflated kids balloon. Mankind can’t survive without this thin skin, without soil.
