Changes made in edit

 
Several small-scale units have been devised for baking charcoal, many with simple common materials. Charcoal making ([[pyrolisis]]) dates back thousands of years in human history, traditionally practiced via earthen pits and mounds. Today, steel drums of different sizes are most commonly utilized due to portability, airflow control options, heat resistance, and availability. See articles below for some examples, and a page on [[Simple Biochar Kilns]].

A variety of feedstocks can be used. Since these often constitute agricultural residues in [[rural communities]], a form of waste is turned into an asset. Possible feedstocks include:
 
 
 
*'''agricultural leftovers:''' straw, rice hulls, corn stalks, chicken/cattle poop
 
*'''Fast-growing biomass:''' bamboo, switchgrass, miscanthus,
 
*'''Wood scrap/salvage:''' unused or recovered wood byproducts
 
*'''Other:''' leaf litter, grasses, macroalgae, bones (high P content),

{{topic header| Biochar2.jpg | Biochar }} {{merge from|Biochar Technology}} '''Biochar''' is a name for [[charcoal]] (pyrolized plant matter), especially in usage as soil amendment. It represents a scalable low-tech strategy for carbon sequestration in the soil. Charcoal has many effects on soil fertility, although it is not much of a nutrient in itself. Some of the world's most productive soils (e.g. Canadian prairies, Russian [http://en.wikipedia.org/wiki/Chernozem Chernozem] / or "black earth") are very rich in organic carbon. This is now thought to be pyrogenic in origin, likely originating from prairie or forest fires. This carbon is often thousands of years old, demonstrating its stability in soil. Besides improving agricultural productivity, charcoal in the soil may serve as a long-term carbon sink, trapping elements that would otherwise contribute to greenhouse climate effects.

Biochar can potentially lock away carbon carbon for hundreds or even thousands of years. If a real commitment were made, massive reductions in atmospheric carbon could be achieved - locking down carbon emissions and increasing the wealth of our soils. In conjunction with other geoengineering projects, biochar may truly hold the key to saving our earth from climate catastrophe. Biochar is also an effective and ecologically friendly soil amendment. It may also have applications in [[energy production]]{{fact}} and as a dietary supplement for animals. Its production was practiced by pre-Columbian Amazonian natives (''"terra preta"''), and natural processes appear to have created a similar affect in other parts of the world, creating rich soils.
