The application of biochar in agriculture can be traced back to 1500 years ago. Before Columbus entered South America, the natives of South America had already used charcoal as an important measure to improve the local soil. This kind of black soil in the central Amazon Basin (Terra Preta de Indio) remains quite fertile to this day.
- Biochar helps reduce straw burning
- Biochar helps to reduce the use of chemical fertilizers
- Biochar helps reduce carbon emissions in production
The application of biochar can increase the quality of crops, improve their nutrient content, and can also slow down the impact of salt stress on crops, so that saline-alkali land can be developed and arable land reserves can be increased.
