Biochar addition has been recommended as a potential strategy for mitigating climate change. However, the number of studies simultaneously investigating effects biochar on CO2, N2O and CH4 emissions sequentially global warming (GWP) is limited, especially concerning its effect native soil organic carbon (SOC) mineralization. An incubation experiment was conducted to investigate physicochemical properties, GWP in treatments with 0% (CK), 1% (BC1) 4% (BC4) cornstalk additions, clarify priming SOC mineralization by 13C tracer technique. Generally, increased pH, cation exchange capacity, total nitrogen, but decreased NH4+-N NO3−-N.

Biochars provide several agricultural and environmental benefits, such as soil health improvement, better crop growth yield, carbon sequestration, decreasing greenhouse gas (GHGs) emissions, regulation of nutrient dynamics. This review highlights the role biochar in transforming soil’s physiochemical biological properties, their impact on improving seed germination seedling growth, altering physiological attributes, enhancing resistance against biotic abiotic stresses, productivity, curtailing GHGs, controlling leaching losses. However, type feedstock used, pyrolysis temperature, application rate method, species largely influence performance under different conditions. Application biochars at low rates help to promote growth. Biochar modified microbial processes rhizosphere increased mineralization enhanced availability for plant uptake. Hence, diseases, reduced heavy metals improved resilience stressors. By providing a comprehensive analysis about variable impacts physicochemical development productivity mitigating problems, this is quite valuable developing an efficient specific with desired functionalities. It could be helpful ensuring food security management environment. Furthermore, identifies knowledge gaps suggests future outlooks commercialization applications large-scale.

Abstract Organic amendments, such as compost and biochar, mitigate the environmental burdens associated with wasting organic resources close nutrient loops by capturing, transforming, resupplying nutrients to soils. While or biochar application soil can enhance an agroecosystem's capacity store carbon produce food, there have been few field studies investigating agroecological impacts of amending co‐compost, produced through composting nitrogen‐rich material, manure, carbon‐rich biochar. Here, we examine impact co‐compost on properties processes conducting a study in which compare agronomic amendment either dairy manure co‐composted compost, soils winter wheat cropping system. amendments were applied at equivalent C rates (8 Mg ha −1 ). We found that all three treatments significantly increased water holding total plant biomass relative no‐amendment control. Soils amended resulted less greenhouse gas emissions than control Biochar also significant reduction leaching alone alone. Our results suggest co‐composting could optimize resource recycling for climate change mitigation agricultural productivity while minimizing losses from agroecosystems.

Biochar is one of the few nature-based technologies with potential to help achieve net-zero emissions agriculture. Such an outcome would involve mitigation greenhouse gas (GHG) emission from agroecosystems and optimization soil organic carbon sequestration. Interest in biochar application heightened by its several co-benefits. Several reviews summarized past investigations on biochar, but these mostly included laboratory, greenhouse, mesocosm experiments.

Climate change, together with soil degradation, biodiversity loss, resource scarcity invasive species, is major threat agricultural worldwide. In this context, new practices have been proposed circumvent or minimize these threats. Yet, mostly focus on farm plant level (e.g., breeding for stress‐tolerant species), frequently overlooking belowground components organic carbon accrual). By interlinking above‐ below‐ground components, likelihood of limiting negative effects current threats can be maximized.
