Evaluation of effectiveness of enhanced-efficiency fertilizers as mitigation options for n2o and no emissions from agricultural soils: meta-analysis
TL;DR: In this paper, a meta-analysis using field experiment data (113 datasets from 35 studies) published in peer-reviewed journals through 2008 was performed to evaluate the overall effectiveness of enhanced-efficiency fertilizers (i.e., nitrification inhibitors, polymer-coated fertilizers, and urease inhibitors) on N2O and NO emissions.
Journal ArticleDOI
Methane and nitrous oxide emissions from rice paddy fields as affected by nitrogen fertilisers and water management
TL;DR: In this article, the authors evaluate the integrative effects of water management and fertiliser application for mitigating greenhouse gas emissions in order to attenuate the greenhouse effect contributed by rice paddy fields.
Journal ArticleDOI
Effect of Organic Matter Application on Methane Emission from Some Japanese Paddy Fields
Kazuyuki Yagi,Katsuyuki Minami +1 more
TL;DR: In this paper, the authors measured CH4 from four Japanese paddy fields by using the closed chamber method and found that the emission was closely related to the decrease of the redox potential (Eh) in paddy soils.
Journal ArticleDOI
Soil microbial biomass, dehydrogenase activity, bacterial community structure in response to long-term fertilizer management
TL;DR: Phylogenetic analysis showed that the change of bacterial community in organic manure-fertilized soil might not be because of the direct influence of the bacteria in the compost, butBecause of the promoting effect of the compost on the growth of an indigenous Bacillus sp.
Journal ArticleDOI
Global estimations of the inventory and mitigation potential of methane emissions from rice cultivation conducted using the 2006 Intergovernmental Panel on Climate Change Guidelines
TL;DR: In this paper, the authors used the Tier 1 method described in the 2006 IPCC guidelines to estimate the global CH 4 emissions from rice fields and found that if all of the continuously flooded rice fields were drained at least once during the growing season, the emissions would be reduced by 4.1 Tg a -1.
