Today, Leyli came to the house with this yuca root in hand, to show me what will grow here with virtually no maintenance (beyond the work of digging it up).
I had been asking him about what we would need to grow yuca (cassava) as a biofuel crop — e.g. water, fertilizer, planting, pruning, harvesting, etc. He says ‘nothing’. This is an example. As it happens, while clearing the slope above the tilapia pond a few months ago, the guys pulled out some plants, but left part of a yuca root. This is what grew from it a few months later — in lousy red clay soil with no watering, no fertilizing, pruning or maintenance. This is great news for my Waste to Energy Center biogas digester — an example of a perfect fuel crop?
