“…Recent studies indicate that biochar addition during the composting process can indeed reduce emissions of both CH 4 and N 2 O probably due to enhanced access of oxygen mediated by biochar. Methane emissions are often drastically reduced by biochar addition, with reported reduction rates of 55% for chicken manure compost with biochar added at 20% w/w (Jia et al 2016), >70% for organic waste compost with biochar added at 10% rate (Sonoki et al 2011), and >80% for municipal solid waste compost with biochar added at 10% w/w (Vandecasteele et al 2016). However, at low biochar additions (e.g.…”

“…At the moment, results are just snapshots of first composting experiments with biochar, and studies include a wide range of experiments from 150 g mixtures in jars (Jia et al 2016), 45 L composting reactors (Malinska et al 2014), 1 m³ gardening compost boxes (Prost et al 2013) to 60×3×2 m windrows with forced aeration and automated mechanical turning (Vandecasteele et al 2016) or daily machine turning (Schmidt et al 2014;Kammann et al 2015) at varying time scales (few weeks to several months). Generally, the value of composting studies would be increased if the resulting compost quality is subsequently evaluated by plant germination and growth tests (e.g.…”

Agriculture and land use change has significantly increased atmospheric emissions of the non-CO2 green-house gases (GHG) nitrous oxide (N2O) and methane (CH4). Since human nutritional and bioenergy needs continue to increase, at a shrinking global land area for production, novel land management strategies are required that reduce the GHG footprint per unit of yield. Here we review the potential of biochar to reduce N2O and CH4 emissions from agricultural practices including potential mechanisms behind observed effects. Furthermore, we investigate alternative uses of biochar in agricultural land management that may significantly reduce the GHG-emissions-per-unit-of-product footprint, such as (i) pyrolysis of manures as hygienic alternative to direct soil application, (ii) using biochar as fertilizer carrier matrix for underfoot fertilization, biochar use (iii) as composting additive or (iv) as feed additive in animal husbandry or for manure treatment. We conclude that the largest future research needs lay in conducting life-cycle GHG assessments when using biochar as an on-farm management tool for nutrient-rich biomass waste streams.

“…Within the first 11 days when the decomposition process was shown to be most rapid in all treatments (Table 3), the biochar dung mixture recorded the lowest temperatures, suggesting slower decomposition. For the biochar-dung mixture, the higher portion of recalcitrant carbon in the mixture will reduce the decomposition rate (Jia et al, 2016).…”

Composting of animal manure had been considered a sustainable alternative method for recycling organic waste. However the process involved had been associated with greenhouse gas emission (CO2, N2O and CH4) which play an active role in global warming. This study evaluated CO2 emissions from biochar-manure co-compost production. Biochar (from rice husk) and manure were mixed in a ratio of 3:1 v/v to achieve a range of different co-compost mixtures. The treatments and controls in triplicates of 18 units were arranged in a complete randomize design. All treatments were incubated at around 28 oC and turned every two days for 2 weeks, and later five days for 39 days. CO2 production in the compost bins was measured by trapping the evolved gas in 5M NaOH. Total CO2 emissions varied over time with higher rates at the beginning of the composting process. Within the first 7 days, total CO2 emissions (587 mg/m2) from cow dung alone was not significantly different from cow dung plus biochar (506 mg/m2). At the latter stages of the composting process, CO2 emission from cowdung and biochar mixture was less than from the other treatments.

“…The impact of biochar addition in conjunction with composting, including their application to soils with manure and manure pellets, on GHG emissions and C sequestration, are summarized in Table 2. Application of biochar during the composting of chicken manure increased peak CO 2 emission, while emissions of both CH 4 and N 2 O decreased [55,56]. Composting of cattle manure with added biochar increased aeration, and hence the activity of methanogens, which reduced CH 4 emission [15].…”

Agroforestry practices that intentionally integrate trees with crops and/or livestock in an agricultural production system could enhance carbon (C) sequestration and reduce greenhouse gas (GHG) emissions from terrestrial ecosystems, thereby mitigating global climate change. Beneficial management practices such as enrichment planting and the application of soil amendments can affect C sequestration and GHG emissions in agroforestry systems; however, such effects are not well understood. A literature review was conducted to synthesize information on the prospects for enhancing C sequestration and reducing GHG emissions through enrichment (i.e., in-fill) tree planting, a common practice in improving stand density within existing forests, and the application of organic amendments to soils. Our review indicates that in agroforests only a few studies have examined the effect of enrichment planting, which has been reported to increase C storage in plant biomass. The effect of adding organic amendments such as biochar, compost and manure to soil on enhancing C sequestration and reducing GHG emissions is well documented, but primarily in conventional crop production systems. Within croplands, application of biochar derived from various feedstocks, has been shown to increase soil organic C content, reduce CO 2 and N 2 O emissions, and increase CH 4 uptake, as compared to no application of biochar. Depending on the feedstock used to produce biochar, biochar application can reduce N 2 O emission by 3% to 84% as compared to no addition of biochars. On the other hand, application of compost emits less CO 2 and N 2 O as compared to the application of manure, while the application of pelleted manure leads to more N 2 O emission compared to the application of raw manure. In summary, enrichment planting and application of organic soil amendments such as compost and biochar will be better options than the application of raw manure for enhancing C sequestration and reducing GHG emissions. However, there is a shortage of data to support these practices in the field, and thus further research on the effect of these two areas of management intervention on C cycling will be imperative to developing best management practices to enhance C sequestration and minimize GHG emissions from agroforestry systems.
