Overview

Climate change is a pressing issue facing people around the globe. Its impacts are devastating: extreme weather events, droughts, water scarcity and wildfires like the one in Jasper two years ago. Biochar mitigates these impacts.  Biochar is a carbon rich matter produced by heating biomass such as dead trees in a kiln with no oxygen in it. This process, known as pyrolysis, traps the carbon inside the biochar as there is no oxygen in the kiln for the carbon to bond to so no carbon dioxide is emitted.  My project's goal was to also investigate biochar's ability to improve the water and nutrient retention of soil leading to improved plant growth. I tested this by performing three experiments: water retention, nutrient retention, and plant growth. My results showed that biochar significantly improves soil's ability to foster plant growth by improving the water and nutrient retention of soil.
