Summary: The study revealed that burned soils in highland maize-upland rice systems have higher organic carbon density (SOCD) than unburned soils, however, burning may not sustain SOCD in the long term, especially in highland areas. Additionally, burning caused fluctuation of SOCD in the short term, with a slight increase in burned soils and steady increase in unburned soils across the maize-upland rice system.

Summary: This study focuses on the limitations of sustainable intensification of maize-based farming systems for smallholder farmers in South Africa, with a case study in the Limpopo province. By combining survey data and quantitative agronomic observations, the researchers evaluated different technology packages over a period of 21 seasons. The simulations showed that combining multiple management interventions resulted in the highest maize grain yields and lowest harvest failure risk. They also found that simple agronomic adjustments based on weather forecasts can turn rainfall variability into an opportunity.

Summary: This study conducted a feasibility study of prescribed burning for crop residues based on air quality assessment in urban regions. The results showed that under controlled factors, prescribed burning can efficiently dispose of crop residues while ensuring air quality in urban areas. The findings can be used to design burning schemes for crop residue and promote sustainable development in agriculture and urban environments.

Summary: Wildfires can have significant impacts on air quality and human health. This study examines the air quality impacts of duff and peat consumption during wildfires in the southeastern United States, focusing on the contributions of fine particulate matter (PM2.5) and ozone to air quality episodes associated with major wildfire events. The study suggests the inclusion of duff burning in global fire emission inventories to improve the modeling of PM2.5 and the understanding of the impacts of wildfires on air quality, human health, and climate.

Summary: Air pollution affects not only the air quality in megacities, but also in medium and small-sized cities due to rapid urbanization, industrialization, and other anthropogenic activities. A study conducted in Chandigarh showed that during a haze episode, PM2.5 concentration was four times higher than usual, and there was a strong correlation between PM2.5 and CO, possibly from burning of solid organic matter.

Summary: This study assesses the impact of crop residue burning emissions on PM2.5 and secondary aerosol at distances far from the sources in north India. The model used underestimated PM2.5 and had poor predictions, but a hybrid model was developed to improve its performance. The contribution of crop residue burning to PM2.5 varied at different locations, as did the contribution of secondary organic aerosol.

Summary: The study presented emissions data of open biomass burning in Northeast China from 2001 to 2017, with crop residue burning contributing the most to the total emissions. Heilongjiang Province was the largest emitter of CO2, with forest fires and grassland fires also influencing CO2 emissions. Emissions showed significant interannual variability, peaking in 2003 and 2008.

Summary: This study examines crop residue burning in India and its impact on emissions. The research reveals that crop burning in India has led to significant increases in CO and greenhouse gas emissions. The states of Punjab and Madhya Pradesh are identified as the areas with the highest burning activity. By utilizing satellite data, it is possible to effectively monitor and manage crop residue burning, providing crucial insights for policy-making and interventions.

Summary: The study found that utilizing lignocellulolytic microbes for in situ decomposition of crop residues is an effective alternative to open field burning. Through field trials targeting rice and wheat residues as well as sugarcane trash, it was observed that lignocellulolytic microbes significantly expedited the decomposition process and improved crop yield.

Summary: The study found that the emission factors (EFs) of PAHs from biomass burning were in the range of 84.5-344 mg/kg, and from coal combustion were in the range of 38.0-206 mg/kg. Emission factors were lower from high-density biomass fuels than low-maturity coal fuels.

Summary: Crop residues management has significant effects on weed control and crop yield. Retaining crop residues can decrease weed density and aboveground dry matter, leading to an increase in maize yield. Long term crop residues retention may be an effective agronomic practice to suppress weed growth.

Summary: Post monsoonal agricultural Crop Residue Burning (CRB) in northwestern India significantly affects the air quality in Delhi. The study shows that the disproportionate increase in PM2.5 in Delhi compared to the source region can be explained by the semi-direct effect of aerosol-boundary layer interactions. Control of local anthropogenic emissions can help alleviate the extreme haze episodes in Delhi.

Summary: Decomposition of crop residues affects soil organic carbon stocks, with different crop types showing different levels of CO2 emissions. Legumes and grasses have lower stability in carbon emission. Soil texture, pH, residue quality, and soil organic carbon concentration are related to CO2 emissions.
