Paddy-upland rotation with Chinese milk vetch incorporation reduced the global warming potential and greenhouse gas emissions intensity of double rice cropping system
TL;DR: Wang et al. as discussed by the authors conducted a field experiment of two years to compared with the effect of two kinds of green manure (CV: Chinese milk vetch and OR: Oilseed rape), and two kindsof cropping system (DR: double rice system and PR: paddy-upland rotation) on greenhouse gases emissions.
Journal ArticleDOI
Low greenhouse gases emissions associated with high nitrogen use efficiency under optimized fertilization regimes in double-rice cropping systems
TL;DR: In this paper, the authors carried out a year-round field experiment to measure methane (CH4) and nitrous oxide (N2O) fluxes, crop yield and nitrogen agronomy efficiency under different fertilization regimes in a subtropical double-rice cropping system.

Biochar decreases methanogenic archaea abundance and methane emissions in a flooded paddy soil.
TL;DR: Biochar application decreased CH4 emissions by reducing methanogenic archaea abundance in the studied flooded paddy soil by reducing meetinghanogens and methanotrophs over two rice cultivation seasons.

TL;DR: In this article, the effects of different fertilizer treatments, including chemical fertilizer treatment, mixed chemical and organic fertilizer treatment (OF), biochar-based slow-release fertilizer treatment(SF), and no fertilizer control treatment (CK) on CH4 emissions and methanogenic community structure in paddy soils were investigated through a field experiment.

Manure amendment increased the abundance of methanogens and methanotrophs but suppressed the type I methanotrophs in rice paddies.
TL;DR: It is revealed that long-term manure amendment in combination with inorganic fertilizers significantly increased the abundance of methanogens and methanotrophs, but suppressed the type I methanOTrophs in rice paddies.

What have we learned from 15 years of free-air CO2 enrichment (FACE)? A meta-analytic review of the responses of photosynthesis, canopy properties and plant production to rising CO2.
TL;DR: The results from this review may provide the most plausible estimates of how plants in their native environments and field-grown crops will respond to rising atmospheric [CO(2)]; but even with FACE there are limitations, which are discussed.

Quantitative analyses of the abundance and composition of ammonia-oxidizing bacteria and ammonia-oxidizing archaea of a Chinese upland red soil under long-term fertilization practices
TL;DR: Significant positive correlations were observed among the population sizes of AOB and AOA, soil pH and potential nitrification rates, indicating that both AOBand AOA played an important role in ammonia oxidation in the soil.

A 3-year field measurement of methane and nitrous oxide emissions from rice paddies in China : Effects of water regime, crop residue, and fertilizer application
TL;DR: In this paper, a 3-year field experiment was conducted to simultaneously measure methane (CH4) and nitrous oxide (N2O) emissions from rice paddies under various agricultural managements including water regime, crop residue incorporation, and synthetic fertilizer application.

A 3-year continuous record on the influence of daytime, season, and fertilizer treatment on methane emission rates from an Italian rice paddy
TL;DR: In this article, an automated, computerized sampling and analysis system was developed which allowed the simultaneous determination of CH4 emission rates at 16 different field plots, covering three vegetation periods.
