The impact of pristine and modified rice straw biochar on the emission of greenhouse gases from a red acidic soil
With the growing awareness of environmental impacts of land degradation, pressure is mounting to improve the health and productivity of degrading soils, which could be achieved through the use of raw and modified biochar materials. The primary objective of the current study was to investigate the ef...

description | With the growing awareness of environmental impacts of land degradation, pressure is mounting to improve the health and productivity of degrading soils, which could be achieved through the use of raw and modified biochar materials. The primary objective of the current study was to investigate the efficiency of pristine and Mg-modified rice-straw biochar (RBC and MRBC) for the reduction of greenhouse gases (GHG) emissions and improvement of soil properties. A 90 days’ incubation experiment was conducted using treatments which included control (CK), two RBC dosages (1% and 2.5%), and two MRBC doses (1% and 2.5%). Soil physico-chemical and biological properties were monitored to assess the effects due to the treatments. Results showed that both biochars improved soil physicochemical properties as the rate of biochar increased. The higher rates of biochar (RBC2.5 and MRBC2.5) particularly increased enzymatic activities (Catalase, Invertase and Urease) in comparison to the control. Data obtained for phospholipid fatty acid (PLFA) concentration indicated an increase in the Gram-negative bacteria (G-), actinomycetes and total PLFA with the increased biochar rate, while Gram-positive bacteria (G+) showed no changes to either level of biochar. As regards fungi concentration, it decreased with the biochar addition, whereas arbuscular mycorrhizal fungi (AMF) showed non-significant changes. The release of CO2, CH4 and N2O showed a decreasing trend over the time. CO2 cumulative emission decreased for MRBC1 (5%) and MRBC2.5 (9%) over the pristine biochar treatments. The cumulative N2O emission decreased by 15–32% for RBC1 and RBC2.5 and by 22–33% for MRBC1 and MRBC2.5 as compared to the control, whereas CH4 emission showed non-significant changes. Overall, the present study provides for the first-time data that could facilitate the correct use of Mg-modified rice biochar as a soil additive for the mitigation of greenhouse gas emission and improvement of soil properties.
•SEM-EDX analysis showed that carbon content decreased while Mg content increased after modification.•RBC and MRBC increased the total PLFA.•Enzymatic activities increased as the rate of both biochar increased.•N2O emission significantly decreased by both biochar.•MRBC decrease CO2 emission by 5% and 9% over RBC at both levels. |
