I know that one of the enviro/greenie worries is the rate of topsoil erosion.
OK, could be a problem, certainly.
But what I\’d like to know is what is the rate of topsoil creation?
We didn\’t start out with some set number, erosion, the activities of worms (??) floods, additional cow shit, breakdown of plant life, whatever, are creating more topsoil at some rate.
So, anyone know what it is?
