According to the [http://www.biochar-international.org/aboutbiochar.html International Biochar Initiative]:
''"Biochar is a fine-grained charcoal high in organic carbon and largely resistant to decomposition. It is produced from pyrolysis of plant and waste feedstocks. As a soil amendment, biochar creates a recalcitrant soil carbon pool that is carbon-negative, serving as a net withdrawal of atmospheric carbon dioxide stored in highly recalcitrant soil carbon stocks. The enhanced nutrient retention capacity of biochar-amended soil not only reduces the total fertilizer requirements but also the climate and environmental impact of croplands.

''Char-amended soils have shown 50 - 80 percent reductions in nitrous oxide emissions and reduced runoff of phosphorus into surface waters and leaching of nitrogen into groundwater. As a soil amendment, biochar significantly increases the efficiency of and reduces the need for traditional chemical fertilizers, while greatly enhancing crop yields. Renewable oils and gases co-produced in the pyrolysis process can be used as fuel or fuel feedstocks. Biochar thus offers promise for its soil productivity and climate benefits."''''

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, probably pyrogenic in origin and originating from prairie or forest fires. The black carbon is often thousands of years old, demonstrating its stability in soil.

When large chunks of wood are used as feedstock, they may need to be crushed before use (beware: coal dust explosion !). Many agrigultural feedstocks and leaf litter will not need to be pulverized.

==Field Trial Results by BlueLeaf / Dynamotive (March 2011) ==

''"Biochar Commercial Agriculture Field Trial in Québec, Canada – Year Three: Effects of Biochar on Forage Plant Biomass Quantity, Quality and Milk Production"''
(Full details of the report [[Media:BlueLeafBiocharForageFieldTrial-Year3Report.pdf| available here‎]])

These are the first biochar field trials undertaken in northerly latitudes (45° north).

Key results include:
* Continued greater biomass growth for the third consecutive year in biochar-amended soils
* Nutritional quality of plants grown in biochar-amended soil is verified by near infrared spectroscopy for first time
* Plant nutrient uptake efficiency and plant nutritional quality is greater in plants grown in biochar-amended soil
* This greater plant nutritional value leads to greater milk production from these forage plants
* In addition to the greater nutritional value of plants grown in biochar-amended soil as well as greater milk production, environmental advantages are anticipated through reduced leaching and reduced greenhouse gas emissions
* These results were achieved with a relatively low biochar application rate (3.9 t/ha), in a northerly climate (N45˚), on normal agricultural soils.

The results of these trials reinforce other research pointing to potentially important advantages for the use of biochar as an agricultural soil amendment, both for economic and environmental reasons.

==Data of effect of biochar on yield==
*The trial cited above by BlueLeaf found modest increases in yield. Dry matter yields were increased by only 2.7% after three years applying biochar. However, the plants grown (forage for [[ruminants]]) were more nutritious on the biochar-treated fields, so researchers project a 19.7% increase in the yield of milk from animals grazing there.
*[http://www.publish.csiro.au/paper/SR07109.htm This trial] found that biochar alone had no effect on yields, but when applied along with N fertilizer, there was a synergistic effect. Biochar alone gave 0% increase, N fertilizer alone gave 95% increase, while biochar and N fertilizer increased yield 266%
*[http://www.springerlink.com/content/dg257hypujtykx3g/ This trial] on maize yields in Ghana found a 91% increase in yield.
*[http://www.publish.csiro.au/paper/SR08036 This study] found a 42% increase in yield when 10 tonnes/hectare were applied and a 96% increase at 50t/ha (that's 5kg/m2 for those of us with less land)
*[http://seachar.org/wordpress/archives/393 This study] found no increase the first year, 28% the next year, 30% the following year, and 140% the year after that. Application was 20t/ha, or 2kg/m2
*[http://cat.inist.fr/?aModele=afficheN&cpsidt=22556100 This] found a decrease in yield, even though the soil was poor in carbon to begin with.

The bottom line is that the biochar will initially take nitrogen out of the soil, potentially reducing yields until it is saturated. This can be avoided by adding nitrogen to the biochar before or during incorporation into the soil.

Jdwheeler42: /* Questions */ Added question on rationale

These are unanswered questions about the sawmill. If you have an answer please edit the page or send and email to jeremymaso at gmail dot com

Thank you!

=Questions=

*What is the rationale for a circular saw instead of a bandsaw?

*Can new teeth be attached to a regular circular saw blade through brazing?

*How should the saws be attached to the vertical posts?
**Maybe with square tubing.

*How sturdy do the saw assembly, posts, and cage need to be?
**The saws should be about 80 lbs, and with the posts and cage about 255 total.

*What forces are going to be acting upon the frame?
