How Rocks Fight Climate Change
Enhanced rock weathering refers to the practice of adding rock dust to the land as a way to combat climate change. At Zumwalt Acres, we are adding basalt rock, Earth's most abundant bedrock, which we source from Rock Dust Local’s Great Lakes Regional Rock.
Week 6, Fall ‘20
On Monday, we woke up, fed the goats, and had our Monday morning team meeting. Then we continued working on grant applications and received helpful feedback from our partners at Delta. After making significant progress on our applications, we went outside to collect wood in preparation for a Tuesday biochar burn. That evening, we sent Jason off on his next adventure! We will miss his beautiful guitar playing, and we’re so happy he came to visit!
The Case for Biochar
We can store carbon from the atmosphere, rebuild degraded soils, increase plant yield, invigorate our urban tree canopy, filter stormwater, remove toxins from the air and soil, and upcycle waste. All this can come from biochar: a special type of charcoal made from wood waste, nutshells, and other organic waste material.
What is Biochar?
Besides cutting CO2 emissions by storing the carbon from organic waste, biochar increases soil fertility, improves plant growth, promotes microbial life, increases water retention, and attracts heavy metals thereby filtering water runoff. Biochar can also be used to augment urban low-impact development such as green roofs, bioswales, and green space to manage stormwater and rebuild degraded soils.
