Agrechar, or biochar, is very useful in not only sequestering carbon, but also helping plants grow more efficiently and potentially stopping global warming. In the video I watched and the article I read, they both mentioned how biochar is made to store the carbon inside of it for hundreds of thousands of years, so it won't release into the atmosphere and cause pollution. The video also mentioned that since the char is very porous, it creates a lot more surface area for the nutrients of the soil to hold on to, therefore making it more helpful for crops and plants. There was also another experiment conducted with two sets of corn crops; one with char in the soil and one without. In the same amount of time, the crops with the char grew a lot taller, healthier, and greener than the crops without char. Since char is only absorbed by the plants that absorb carbon, this char is actually carbon negative. This means that if made on an industrial scale, biochar could help change the world by potentially slowing the process of global warming.
