Biochar as a Soil amendment: implications for soil health, carbon sequestration, and climate resilience

Discover Soil., Год журнала: 2025, Номер 2(1)

Опубликована: Март 3, 2025

Abstract Biochar, a carbon-rich material produced through the pyrolysis of organic biomass, has gained increasing attention as sustainable soil amendment due to its potential enhance health, improve agricultural productivity, and mitigate climate change. This review explores multifaceted benefits biochar, including ability sequester carbon for long periods, thereby reducing atmospheric greenhouse gases. Biochar’s unique properties, such porous structure, high cation exchange capacity, nutrient retention capabilities, significantly fertility, water-holding microbial activity. These improvements increase crop resilience against drought, erosion, loss, supporting climate-resilient systems. Additionally, biochar’s application can lower nitrous oxide methane emissions from soils, further contributing change mitigation. However, effectiveness biochar is influenced by factors feedstock type, conditions, rates. Understanding these variables crucial optimizing biochar's use in different types environmental conditions.

Biochar’s effect on the soil carbon cycle: a rapid review and meta-analysis

Biochar, Год журнала: 2024, Номер 6(1)

Опубликована: Окт. 17, 2024

Abstract Biochar offers opportunities for improving soil carbon (C) sequestration and reducing CO 2 emissions to the atmosphere. It has emerged as a strategy mitigating climate change cycle (SCC). While previous review studies have primarily investigated effects of biochar on greenhouse gas (GHG) emissions, considerable research gap remains regarding its impact SCC. The present study aims bridge this by examining main SCC components: total flux, microbial respiration, C sequestration. We conducted global meta-analysis which included 75 250 observations. results show an average 11% increase in flux from biochar, but confidence interval (CI) slightly touches no-effect line (CI [0%, 23%]). Total respiration unchanged after application (10%, CI [− 2%, In contrast, benefits 61% [36%, 90%]). Our analysis identified key predictors affecting experimental design, continent, rate, feedstock type, pyrolysis temperature. Incubation experiments reveal all components. Middle East, Europe, Asia exhibit potential enhancing with biochar. Higher rates amplify respiration. Manure enhances while woody influences flux. Furthermore, lower temperatures promise conclusion, holds sequestration, inconclusive.
