Slash and Char

Charcoal in the soil ... Yes, but I need a backyard how-to!!!

snips:
This black carbon lasts for ten’s of thousands of years in the soil as opposed to a few seasons [of our fertilizer] at best. The result is a soil with chemical and biological properties that convert unproductive tropical oxisols to fertile soils that are still farmed even 1000 years after the original people have disappeared.

... about 3 times the crop yield
