Many thanks Steve. You are always a lighthouse of
Info. Ill read the references with
interest. I wish we had something like ATTRA here in
Mx.
Re. Sunn Hemp, I found the USDA Soil Quality,
Technical Note No. 10 and an article from U. Hawaii,
SUNN HEMP TROPIC SUN AS A COVER CROP IN EDIBLE
GINGER PRODUCTION Dwight Sato*, CTAHR-Hilo, Bob Joy,
NRCS-Molokai, Matthew Wung, NRCS-Hilo,, which
concludes (amidst a faulty experimental design IMO) :
Using sun hemp as a cover crop under non-irrigated,
rainfed conditions may not be a suitable sustainable
practice for nematode control in a long term ginger
crop.
A local INIFAP experimental station has done some
research with crotalaria and I could probably get some
seed. The yields and growth conditions are something
to be considered. Thanks for bringing it to my
attention "soilculturebiodi".
