Changes in fertilizer‐induced direct N₂O emissions from paddy fields during rice‐growing season in China between 1950s and 1990s

Abstract

Nitrogen fertilizer-induced direct nitrous oxide (N 2 O) emissions depend on water regimes in paddy fields, such as seasonal continuous flooding (

Practices for Reducing Greenhouse Gas Emissions from Rice Production in Northeast Thailand

“…Fertilizer application is important from a climate change perspective due to energy-intensive production and the positive relationship with N 2 O emissions from soils [55,56]. This was consistent with our result for the land management practices at site I5 (Table 5), which generated the highest N 2 O due to the high chemical fertilizer application and amount of burned rice residues.…”

Greenhouse gas budget for terrestrial ecosystems in China

“…Nitrous oxide emission from rice fields that are continuously flooded during the rice growing period is negligible. Generally, N 2 O emission from rice fields is less than from uplands, but substantial N 2 O emission has been observed from rice fields that were drained during the rice-growing period, and emission increased with the number of times the fields were drained during the mid-season of rice growth [70,71].…”

Net global warming potential and greenhouse gas intensity from the double rice system with integrated soil–crop system management: A three-year field study

“…The total CH 4 emissions from Chinese rice paddies are estimated to be 7.41 Tg CH 4 year À1 , accounting for 29.9% of the world total (25.55 Tg CH 4 year À1 ) (Yan et al, 2009). The direct N 2 O emissions during the rice growing season, measured at a rate of 32.3 Gg N 2 OeN, account for 8e11% of the total N 2 O emissions from Chinese croplands (Zou et al, 2009).…”
