Talk:Sawdust

From Wikipedia, the free encyclopedia

Some engineers such as Diesel engine can combust sawdust directly (or mixed with fuel) and power your machines, though the ash - which makes a good fertilizer if scattered thinly over a forest from an airplane to replenish the trace-minerals, but dumped into high concentration local pits - can cause an even worse environmental issue.

[edit] Hydroponic Use of Sawdust

Canada has used its cheap supply of sawdust as a medium for hydroponic industry to rasie strawberries and tomatoes. Warning: for logs that have been transported in ocean water, the salt needs to be leached out to make the sawdust useable. Note: red cedar cannot be used as it is toxic to plants.

Sawdust is one of several media that is used in column culture, where the medium is placed in a column that has openings space along the sides where crops like strawberries and tomatoes can grow. Nutrient fluid is driped or pumped from the top, and collected at the bottom for reuse. Occasional adjustments on the nutrient fluid must be made. 71.114.182.236 (talk) 02:24, 25 January 2008 (UTC)
