Inappropriate method and timing of N fertilizer application was found to result in 50–60% N
losses. Recent nitrogen transformation studies indicate that NH 3 volatilization in lowland …

Strategies used to reduce emissions of N 2 O and CH 4 in rice production normally include
irrigation management and fertilization. To date, little information has been published on the …

Submerged soils and rice fields are known sources of nitrous oxide (N2O) but also act as its
sinks. Nitrous oxide uptake (movement from atmosphere into soil) and consumption …

This paper reported the quantitative contribution of three important dry‐wet cycles to N2O
emission in annual rotation, and compared N2O emission patterns during rice and wheat …

Fertilized rice paddy soils emit methane while flooded, emit nitrous oxide during flooding
and draining transitions, and can be a source or sink of carbon dioxide. Changing water …

A new chamber method and a stripping method were developed for field measurements of
the rate of N2O emission from the water surface and for determinations of dissolved N2O in …

Climate change has many facets, including changes in long-term trends in temperature and
rainfall regimes with increasing year-to-year variability and a greater prevalence of extreme …

通过田间试验, 采用静态箱法研究相同施氮量条件下, 施用尿素, 控释肥及尿素与控释肥配施(
尿素与控释肥以3∶ 7 配合施用) 对稻田N 2 O 排放的影响. 结果表明: 与单施尿素处理相比 …
