Summary
This critical review examines biochar incorporation as a tool to advance sustainable agriculture through multiple pathways: improving soil health, enhancing crop productivity, and reducing greenhouse gas emissions. The authors synthesise peer-reviewed evidence across these domains whilst also evaluating the practical feasibility of biochar adoption in farming systems. The review suggests biochar holds promise for soil carbon sequestration and soil function improvement, though efficacy appears context-dependent.
UK applicability
Biochar incorporation may be relevant to UK soil improvement strategies, particularly in regions with degraded soils or organic matter deficits. However, UK applicability depends on local feedstock availability, production costs, and compatibility with existing arable and mixed farming practices; the review's global scope may require place-based validation.
Key measures
Soil health indicators (organic matter, microbial activity, physical properties); crop productivity (yield, growth metrics); greenhouse gas emissions (CO₂, CH₄, N₂O); soil carbon stocks; nutrient availability; economic and operational feasibility
Outcomes reported
The critical review synthesises evidence on biochar's effects on soil health, crop productivity, and greenhouse gas emissions, while assessing practical feasibility for sustainable agriculture. Specific metrics appear to include soil carbon sequestration, nutrient retention, crop yield responses, and mitigation of methane and nitrous oxide emissions.
