Effect of animal manure, crop type, climate zone, and soil attributes on greenhouse gas emissions from agricultural soils—A global meta-analysis

چکیده
Agricultural lands, because of their large area and exhaustive management practices, have a substantial impact on the earth’s carbon nitrogen cycles, agricultural activities consequence in discharges greenhouse gases (GHGs). Globally, (GHGs) emissions especially dioxide (CO 2 ), methane (CH 4 ) nitrous oxide (N O) from sector are increasing due to anthropogenic activities. Although, application animal manure soil as an organic fertilizer not only improves health production but also has significant GHGs emissions. But extent response under diverse environmental conditions is still uncertain. Here, meta-analysis study was conducted using field data (48 peer-reviewed publications) published 1989 2019. Meta-analysis results showed that poultry considerably increased CO , CH 4, N O than pig cattle manure. Furthermore, ( l n R ¯ = 0.141, 95% CI 0.526–0.356) GWP (global warming potential) total While, effects occurred at rate >320 kg ha −1 >60% water filled pore space. The maximum concentrations were observed neutral soils 3.375, 3.323–3.428), alkaline 1.468, 1.403–1.532), acidic 2.355, 2.390–2.400), respectively.

Predicting Greenhouse Gas Emissions and Soil Carbon from Changing Pasture to an Energy Crop
Bioenergy related land use change would likely alter biogeochemical cycles and global greenhouse gas budgets. Energy cane (Saccharum officinarum L.) is a sugarcane variety and an emerging biofuel feedstock for cellulosic bio-ethanol production. It has potential for high yields and can be grown on marginal land, which minimizes competition with grain and vegetable production. The DayCent biogeoc...
متن کاملSoil Greenhouse Gas Emissions in the Life Cycle Assessment of Cellulosic Ethanol From Crop Residue
Concerns about climate change and the increasing cost of fossil fuels have led to interest in the development of renewable biofuel pathways for reducing greenhouse gas (GHG) emissions. The use of corn residue as a potential source of biomass feedstock for cellulosic ethanol production has been favored as cost effective. Previous research has shown that crop residue removal can cause a loss of s...
متن کاملResidue Placement and Rate, Crop Species, and Nitrogen Fertilization Effects on Soil Greenhouse Gas Emissions
High variability due to soil heterogeneity and climatic conditions challenge measurement of greenhouse gas (GHG) emissions as influenced by management practices in the field. To reduce this variability, we examined the effect of management practices on CO2, N2O, and CH4 fluxes and soil temperature and water content from July to November, 2011 in a greenhouse. Treatments were incomplete combinat...
متن کاملAgricultural opportunities to mitigate greenhouse gas emissions.
Agriculture is a source for three primary greenhouse gases (GHGs): CO(2), CH(4), and N(2)O. It can also be a sink for CO(2) through C sequestration into biomass products and soil organic matter. We summarized the literature on GHG emissions and C sequestration, providing a perspective on how agriculture can reduce its GHG burden and how it can help to mitigate GHG emissions through conservation...
