N. Michigan University Makes Use Of Wood Ash

Posted: Updated:

MARQUETTE, Mich. (AP) - Northern Michigan University is taking wood ash from its biomass plant to help fertilize farmland instead of dumping it in a landfill.

The Mining Journal of Marquette reports that the byproduct acts as a liming agent and neutralizes acidic soil. Farmers buy lime to improve their soil and increase their crop yield, so it made sense to take the wood ash from the Ripley Heating Plant to a Chocolay Township farmer.

Wood chip waste from saw mills is processed as an alternative fuel source at the plant that opened this year. The wood ash byproduct is not a fertilizer itself, but complements nitrogen and helps crops absorb nutrients from the soil.
