I have a question about building soil nutrients. I remember during
my PDC seeing a chart which listed different cover crops/weeds/etc
which, over time, would build up specific nutrients in the soil. I think
this table might have been one of the things in Permaculture 1 or
Permaculture 2 which had been left out of the Design Manual, but I could
be wrong. Does anyone know where this information is printed, or better
yet, if it exists online somewhere?
