“…The number of studies using upland soils and measuring CH 4 consumption with/without biochar is currently not large. Kollah et al (2015) observed significantly increased CH 4 consumption rates in a lab study with tropical soil amended with biochar (with or without organic amendments), as did Karhu et al (2011) in in-field boreal, ploughed grassland soil. Karhu et al (2011) assumed that the observed doubling of the CH 4 consumption in the ploughed grassland soil was due to altered gas diffusivity and water holding capacity (which increased by 11%).…”

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.

“…Result highlighted that organic farming can significantly decrease global atmospheric CH 4 budget in addition to improving soil physical and biological properties. Kollah et al, (2015) showed that biochar enhanced the methane consumption potential in tropical Vertisols, particularly smaller sized fractions (<0.25 mm), and could be an effective strategy to mitigate atmospheric CH 4 . Organic amendments like vermicompost and FYM were more effective than poultry manure in improving methane consumption in soils.…”

The research efforts in microbiology over last two decades have focussed on assessing the microbial diversity in various soil types and cropping systems in all agro-eco-regions, including extreme environments resulting in creation of a vast repository of microorganisms, free living and endophytes. A marked departure from the past is their identification by both conventional and molecular methods, resulting in discovery of many novel species. The effects of various soil and agronomic management practices were assessed on soil microbial diversity and soil health by both classical and metagenomic approach. The beneficial effects of organic and integrated farming, and adverse effects of chemical intensification have been assessed, leading to the identification of actinobacteria as important players in maintaining soil health. A major impact has been the firm attention received from policy makers on the urgent need to conserve soil biodiversity and improve soil health. Identification of rapid methods of soil biological health assessment, improved rhizobial inoculants, microbial technology for rapid in situ and ex situ residue and waste breakdown, and mitigating climate change effects are the current priorities. Future priorities include assessment of the structure and function of the vast reservoir of unculturable microbes; deleterious microorganisms, assessment of soil-plant-microbe continuum and plant immunity modulation by microbes; rhizosphere engineering, role of archaea in maintaining soil health, microbial methods to improve soil organic matter formation; assessment and quantification of ecosystem services rendered by agriculturally important microorganisms; and improved microbial technology for biofertilizers and delivery systems. The tremendous advances in agricultural microbiology in last two decades in India are a cause for optimism that solutions will be forged for the above challenges using both classical and modern approaches, thereby ushering in the process more sustainable agricultural systems.

Biodegradation of chlorpyrifos under the influence of fertilizer application and climate factors such as elevated CO2, temperature and moisture was studied. Soybean was grown in control, inorganic, organic and integrated (both inorganic and organic) fertilized fields. Rhizospheric soils collected during the vegetative growth phase were amended with chlorpyrifos (10 μg/g soil) and incubated under different climate factors. The climate factors were CO2 concentration (400, 800 ppm), temperature (25, 45°C) and moisture-holding capacity (60, 100%). Chlorpyrifos degradation rate varied from 0.28 to 0.65 μg/g soil/d. The abundance of 16S rRNA gene copies of eubacteria varied from 13 × 106 to 7 × 105/g soil. Actinomycetes-specific 16S rRNA gene copies were in the range of 62.5 × 105 to 18.5 × 103/g soil. Microbial abundance was high in organic amended soil and low in control soil irrespective of climate factors. Elevated CO2 and high temperature inhibited (P < 0.05) chlorpyrifos degradation rate and the abundance of 16S rRNA genes of eubacteria and actinomycetes. Chlorpyrifos degradation followed as: organic > integrated > inorganic > control. The degradation rate was positively correlated (P < 0.01) with the soil organic C, available N, water-stable aggregates and mean weight diameter of the soil aggregates of soil. Principal component analysis denoted temperature and fertilizer as the major components of variation. The study highlights that elevated CO2 and temperature affect chlorpyrifos biodegradation; however, the effect can be alleviated by the amendment of organic fertilizer.
