[permaculture] Fast growing nitro fixers, semi tropics

good to know.

not bad overstory trees to include even if not support sp. though.

in this case, I would lower the planting ratios to true n-fixing overstory
at initial planting, but might use them as my permanent overstory and be
more selective with variety.

besides nodule formation, growth rate and above ground tissue analysis of
C:N are useful for fnal analysis and use plans.

where I have seen and eaten Tamarind, they seem to prefer 'drier' ground,
so siting with drainage like on a swale mound would be my first choice in a
wetter area like florida.

Carob as well I would strive for drier microclimates in humid areas, but
still throw it into the mix as a trial. or ask locals for a reference

I always appreciate any other research or data or anectodes.

some quick links


this is an interesting find
http://hort.ufl.edu/database/documents/pdf/tree_fact_sheets/lysbaha.pdf the
cuban tamarind that grows wild in Florida totally different genus according
to this...

tossing pinion and walnut seeds in the ground to prep for the wet season
best of luck in your works,
