It's not a complete course but you could try and make
Terra Preta soil. There was a Ted talk recently that spoke about it as well. It seems to me that in trying to create terra preta you would invariably be doin' some
permaculture. Like using mulch plants, sheet composting and adding fine ash/charcoal. The whole picture of terra preta is still foggy, so anyone who can crack the puzzle of how to deliberately make it would be well off for sure.
From my understanding the defining points of a jungle are that most of the carbon/organic matter is up in the tree canopies, and the nutrients at ground level leech away fast as a result from the first point. You could go along with those two trends, and grow a lot of (possibly difficult to harvest) tree fruit and vines and other jungle edibles. Or you could work somewhat against the natural flow and try to improve the depth/fertility of the soil you are working with in order to grow/harvest continually the type of plants that spring up after a tree fall in the jungle, as well as any more conventional fruit/veggie.
I'd say do both of course. And spend a lot of time in the Zone 5 just observing the insane amount of plants you have at your fingertips in the jungle.
