Terra Preta is dark soil that was created when ancient Amazonians disposed of waste by slow burning. While it was not created with an aim to help crop production, the soil is extremely fertile. Modern farmers are reaping the benefits.
Biochar is the modern application of the ancient methodology called slash and char. Biochar captures airborne carbon and stores it in the ground, thus reducing greenhouse gases. Methane and nitrous oxide soil emissions are dampened as well. Not to be confused with slash-and-burn, where farmers release greenhouse gases when they prepare fields by cutting and burning, slash-and-char depends on a low-heat smoldering burn. It also occurs after naturally-occurring fires as they slowly burn out.
The excellent video above explains biochar in great detail.
What Makes This Trend Stand Out
- Biochar
- The use of biochar as a method to capture and store airborne carbon, reducing greenhouse gases and soil emissions.
- Terra Preta
- The ancient Amazonian soil known as Terra Preta, which is highly fertile and beneficial for crop production.
- Slash and Char
- Application of the ancient method of slash and char to create biochar, offering a sustainable solution to reduce CO2 pollution.
Sectors Adopting This
- Agriculture
- The agricultural industry can implement the use of biochar and Terra Preta to enhance crop production and reduce greenhouse gas emissions.
- Environmental Technology
- The environmental technology industry can harness the potential of biochar and slash and char methods as disruptive solutions to address CO2 pollution.
- Sustainable Farming
- In the field of sustainable farming, the utilization of biochar holds immense potential to improve soil fertility and mitigate climate change.
