Comparison of manual and automatic methods for measurement of methane emission from rice paddy fields
      
Plant/microbe cooperation for electricity generation in a rice paddy field
      
Here, we report the application of an MFC system to electricity generation in a rice paddy field.
      
Methane production in three types of rice paddy soil was investigated under greenhouse conditions.
      
Rice straw polysaccharides are one of the major C sources for CH4 formation in anoxic rice paddy soils.
      
Eukaryotic communities associated with the decomposition of rice straw compost in a Japanese rice paddy field estimated by DGGE
      
It is, therefore, concluded that slag-type silicate fertilizer could be a suitable soil amendment for reducing CH4 emissions as well as sustaining rice productivity and restoring the soil nutrient balance in rice paddy soil.
      
Importance of data on Cd in rice paddy soil as a missing link is discussed.
      
Reducing fertilization of rice paddy may not work well to mitigate the non-point source nutrient loading in the range of normal farming practices.
      
Abundance of rare earth elements in rice paddy soils from three regions of Sri Lanka
      
It is evident that the infiltration from rice paddy is of great importance to the economy, environment, and water resources conservation in Taiwan.
      
Effect of slope on surface drainage in converted rice paddy
      
Due to the recent regulation of rice production in Japan, it has become necessary to convert rice paddy to other field crops production.
      
These results give a basis for determining a slope on a rice paddy in terms of surface drainage improvement.
      
The methods to consolidate scattered tenanted lots into large rice paddy lots by the land consolidation projects in Japan
      
In order to realize large rice paddy lots of more than several hectares, it is necessary to consolidate small scattered leased farm lots of core tenant farmers, but it is supposed to be very difficult.
      
In order to clarify how to consolidate those leased lots into large rice paddy lots, I investigated five land consolidation project areas in which large rice paddy lots of more than several hectares were constructed for core tenant farmers.
      
The result shows that (1) large rice paddy lots for core tenant farmers were settled in relatively inferior areas of the project areas, for instance, far from the land owners' residence area.
      
Quantification of the effect of rice paddy area changes on recharging groundwater
      
Nitrous oxide (N2O) emission from flooded rice paddy fields was continuously measured by the closed chamber method at an experimental plot in Thailand for a whole cultivation period.
