[1] Isotopomer ratios of N2O (bulk nitrogen and oxygen isotope ratios, δ15Nbulk δ18O, intramolecular 15N site preference, SP) are useful parameters that characterize sources this greenhouse gas also provide insight into production consumption mechanisms. We measured isotopomer emitted from typical Japanese agricultural soils (Fluvisols Andisols) planted with rice, wheat, soybean, vegetables, treated synthetic (urea or ammonium) organic (poultry manure) fertilizers. The results were analyzed...
Rice (Oryza sativa L.) production is facing major challenges, including scarcity of irrigation water and ongoing climate change. Modifications the current cropping techniques could increase yield, save water, mitigate greenhouse gas emission. We investigated effect planting methods (young seedlings, wide spacing with alternate wetting drying [YW-AWD], old narrow continuous flooding [ON-CF], in-between two [IB-AWD]) rice varieties on methane (CH4) (N2O) emissions during crop seasons. The...
Biochar is a highly stable carbon compound produced through pyrolysis, and it has been widely studied for its potential to enhance soil fertility sequestration. However, the impact of fresh residual biochar not thoroughly explored. Therefore, comparative study on were conducted at filed conditions wheat cultivation, using randomized block design. A (S1), previous season crop (S2) two old (S3) with nine different treatments varied amounts rice husk straw along fertilizers (recommended doses...
The seasonal courses of methane (CH 4 ) and nitrous oxide (N 2 O) fluxes were simultaneously monitored in a paddy field using closed chamber system with automated gas sampling analyzing equipment. Water management fertilizer application practices followed Japanese conventional ones. CH flux gradually increased after the first flood irrigation reached ∼150 mg m −2 d −1 at beginning July. After summer drainage, however, dropped rapidly to almost zero within few days. then again according...
A laboratory study was conducted to the effects of liming and different biochar amendments on N2O CO2 emissions from acidic tea field soil. The first experiment done with three rates N treatment; 300 (300 kg ha-1), 600 (600 ha-1) 900 (900 four bamboo amendment; 0%, 0.5%, 1% 2% biochar. second biochars at a rate (rice husk, sawdust, bamboo) control lime treatment (dolomite) two moisture levels (50% 90% water filled pore space (WFPS)). results showed that dolomite amendment significantly...

Since crop rotation between paddy rice and upland crops is widely conducted in Japan other Asian countries, the effect of on greenhouse gas emission should be clarified. In this study, methane (CH4) nitrous oxide (N2O) fluxes were simultaneously measured for two years from 2004 to 2005 a field with three different cultivation histories, i.e. consecutive (PR), single cropping (UR), double soybean wheat (SW) preceding 2002 2003. 2004, cumulative CH4 emissions UR SW plots 511 2817 g m−2 y−1,...
Water-intensive systems of rice cultivation are facing major challenges to increase grain yield under conditions water scarcity while also reducing greenhouse gas (GHG) emissions. The adoption effective irrigation strategies in the paddy system is one most promising options for mitigating GHG emissions maintaining high crop yields. To evaluate effect different alternate wetting and drying (AWD) on from dry wet seasons, a field experiment was conducted at Tamil Nadu Rice Research Institute...
Azolla (Azolla filiculoides) is a common aquatic fern that has been used successfully as dual crop with lowland rice. It grows rapidly and the ability to fix N2 for rice paddy. However, its ecological significance especially on greenhouse gases emissions remains unclear. To investigate effect of azolla cover methane (CH4) nitrous oxide (N2O) from paddy, pot experiment two treatments, control (rice plant only) plus covering flooding water), was carried out in Tsuruoka, Yamagata, Japan, 2016....
Poultry-litter biochar and Azolla as green manure amendments are reported to enhance paddy soil fertility rice yields. However, whether their co-application in lowland paddies has synergistic effects those benefits accompanied by greenhouse gas (GHG) emissions remains unknown. The objective of this study was determine the poultry-litter (hereafter: biochar) its with Azolla), on simultaneous methane (CH4) nitrous oxide (N2O) from a planted during single growing season Tsuruoka, Yamagata,...
Abstract Understanding the current status of biodiversity is crucial to preventing its loss in a changing world. We examined changes geographical range size and abundance 165 bird species breeding Japan during past 40 years, as well temperature niche 20 years. Higher temperatures were recorded within ranges non-native than those native species, we detected range-size expansion increased among species. Although open-land exhibited reductions from 1970s 1990s, many recovered only few declined...
