[1] The annual and interannual characteristics of nitrous oxide (N2O) emissions from conventional vegetable fields are poorly understood. We carried out 4 year measurements N2O fluxes a cultivation area in the Yangtze River delta. Under fertilized conditions subject to farming practices, approximately 86% total release occurred following fertilization events. direct emission factors (EFd) 12 individual seasons investigated ranged 0.06 14.20%, with mean 3.09% coefficient variation (CV) 142%....
Abstract Although synthetic nitrogen fertilizers play an important role in increasing cereal grain yields, there have been increased concerns about their intensive utilization and environmental consequences. The overall goal of this study is to gain insight into the integrated evaluation greenhouse gas emission nitric oxide (NO) release yield as affected by fertilization a subtropical rice‐wheat rotation system. assessment was based on four consecutive yearly measurements fluxes methane (CH...
Spartina alterniflora is one of the most noxious invasive plants in China and many other regions. Exploring environmentally friendly, economic effective techniques for controlling great significance management coastal wetlands. In present study, different approaches, including mowing waterlogging, tilling herbicide application, were used to control alterniflora. The results suggest that integrated approach waterlogging could eradicate alterniflora, haloxyfop-r-methyl kill almost all at end...
Abstract Increasing levels of atmospheric CO 2 are expected to enhance crop yields and alter soil greenhouse gas fluxes from rice paddies. While elevated ( ) effects on CH 4 emissions paddies have been studied in some detail, little is known how might affect N O or yield‐scaled emissions. Here, we report a multi‐site, multi‐year in‐situ FACE (free‐air enrichment) study, aiming determine Chinese subtropical systems as affected by . In this tested various fertilization residue addition...
As an invasive species, Spartina alterniflora has caused serious harm to many coastal wetland ecosystems, and its prevention control have become the top priority of protection. To explore difference in effects different herbicides on S. optimize chemical technology, four experiments were carried out this study, namely, herbicides, doses, dilution ratios, mowing + herbicide. The results showed that (1) 75 days after application herbicide, high doses glyphosate (8.0 kg ha−1), cyhalofop-butyl...
The invasive species Spartina alterniflora has significantly disrupted the ecological stability of coastal wetland ecosystems. Consequently, its control become an important aspect conservation. When controlling S. alterniflora, it is imperative to assess impacts methods. In this study, effects different methods, i.e. "mowing + flooding" (MF) and plowing" (MP), on soil carbon nitrogen contents in wetlands were investigated Yellow River Delta, China. results showed that organic carbon,...
Denitrification-induced nitrogen (N) losses from croplands may be greatly increased by intensive fertilization. However, the accurate quantification of these is still challenging due to insufficient available in situ measurements soil dinitrogen (N2) emissions. We carried out two one-week experiments a maize-wheat cropping system with calcareous using 15N gas-flux (15NGF) method measure N2 fluxes following urea application. Applications 15N-labeled (99 atom%, 130–150 kg N ha−1) were followed...
The establishment of sown pasture is an important agricultural practice in many landscapes. Although both native grassland and play a key role the global carbon cycle, due to lack data field experiments, our understanding CH4 fluxes CO2 emissions remains limited, especially when it comes pasture. We measured ecosystem respiration response variety potential drivers (soil temperature, soil moisture, ammonium nitrogen, nitrate nitrogen dissolved organic carbon) CG (continuous grazing), RG...
As an invasive species, Spartina alterniflora has caused serious harm to many coastal wetland ecosystems, and its prevention control become the top priority of protection. In order explore difference effects different herbicides on S. optimize chemical technology, four experiments were carried out in this study, namely, herbicides, doses, dilution ratios, mowing + herbicide. The results showed that: (1) After two a half months herbicide application, high doses glyphosate, cyhalofop-butyl or...
