Biochar harkens back to the ancient practices of carbon sequestration and wood-burning pyrolysis, where trees and other organic materials were heated in low oxygen conditions to produce a black, porous and high-carbon-content product known as biochar. The process has been used by cultures worldwide to improve agricultural soil, sequester carbon, and stabilize nutrients.

Though the modern term "biochar" was coined in 2006, its use dates back thousands of years. Historical knowledge indicate that pyrolysis and charcoal production have been practiced for over 2,000 years. Traditional practices involved incorporating biochar into soil to enhance its fertility and hold water, leading to increased crop yields. Examples of biochar-based agriculture include South America's carbon-rich soils and Australia's Terra Preta dark soils.

Research on modern biochar production has shed light on its potential as a carbon sequestration tool and a soil amendment. Charcoal can improve soil fertility by releasing nutrients, acting as a soil filter by capturing and eliminating pollutants and supporting beneficial microbial life. Biochar can improve crop yields and plant resilience in regions suffering crop loss due to nutrient deficiencies, irregular water availability, and pollution.

Case studies and field experiments have demonstrated the effectiveness of biochar in various settings, including tropical and arid ecosystems. Additional parameters of interest include biochar properties like particle size, elemental content, and surface properties, which have been linked to quality and performance of biochar. While there's potential in biochar's benefits, experimentation is needed to understand the long-term impact it has on agricultural productivity, ecosystem health, and the environment.
