1. i have some issues with your interpretation of how carbon is captured.

But your general summary is right. Plant material return carbon to soil and this is a useful process. Charring plant matter isn't a good idea because that can drive or modify compounds in plant matter. Best practices rely on composting of plant matter, that process takes longer. The point you made on bamboo must be highlighted. Bambo is a plant that can be used for every use from animal feed, to clothing to building materials. Bambo grows almost anywhere from dry land to wetland. Bambo is an excellent replacement for agricultural water intensive cotton is infinitely better than synthetics. Bambo fabric has the sheen of silk, bit looks like cotton fabric.

To me organic based agriculture has value because it reduces the amount of resources required to product food and materials for clothing and building. I am a bit skeptical of the claim that manufactured fertilizers leave harmful residues in food. My problem with manufactured fertilizer is the amount of energy and raw materials that go into their manufacture.
