Thanks, Georg-- the details helped...
Fortunately I  speak German-- one of the advantages of being maried to a
Swiss for these last 20-odd years....So I will look up the original text on
your website...

Everyone else-- this information is most pertinent! When we analyse what
happens in industrialized agriculture, we see that this cycle will be
totally disrupted, and that it is very important for soil/plant health.
This is one of the best arguments I know for not disturbing( plowing) the
soil and not using soluble  fertilizers.  It deserves more serious
research...
