I see there are more people interested, so here is where I found the information: www.apitherapy.com/plants.php
For those in US that are not familiar with European system, 1 ha=2.47 acres or 10000 square meters (100 x 100) and 1 kg=2.2 lb.
Hope this helps. I guess next will be to find affordable nurseries for the best producing plants/trees. I am trying seeds but it doesn't look too good.
