Runoff characteristics of nutrients from an agricultural watershed with intensive livestock production.
- T. Kato, H. Kuroda, H. Nakasone
- Environmental Science
- 30 April 2009
Summary Among the various agricultural activities, livestock production can have a serious impact on water resources because livestock wastes are often stored in earthen waste storage ponds and are… Expand
Detection of Anammox Activity and 16S rRNA Genes in Ravine Paddy Field Soil
An anammox assay involving a 15N tracer and gas chromatography-mass spectrometry revealed that the potential anammox activity accounted for 1 to 5% of total N2 production in a ravine paddy field,… Expand
Nitrogen removal from water containing high nitrate nitrogen in a paddy field (wetland).

- 1 November 2003
Nowadays, it has become very common to find in Japan that nitrate nitrogen concentrations are very high in spring water and in well water where the land use of a watershed is agricultural. We have… Expand
A DISTRIBUTED WATER QUALITY TANK MODEL FOR NITROGEN LOAD REDUCTION BY ARTIFICIAL WETLANDS
- T. Kato, H. Kuroda, H. Nakasone
- Environmental Science
- 2005
A distributed water quality tank model was developed to evaluate nitrogen load reduction by artificial wetlands in the A10 area, located in the Lake Kasumigaura watershed in Japan. In order to… Expand
Causes of animal extinction in small irrigation reservoirs in Japan and requirements for future re‐establishment
- H. Nakasone, H. Kuroda, T. Kato
- Environmental Science
- 1 March 2002
In the past, small irrigation reservoirs were constructed only for rice paddy irrigation in Japan. Many of the watersheds for these irrigation reservoirs were forests. These watersheds have been… Expand
The Effect of Nitrogen Fertilizer Use at Tea Yards on Water Quality of an Irrigation Reservoir.
- H. Nakasone, Izumi Yamasita, H. Kuroda, T. Kato
- Environmental Science
- 2000
We found a special irrigation reservoir in which there are no algae, insects, or fish. Therefore, we have surveyed the water quality of an irrigation reservoir to find the reason for no living… Expand
Continuous Measurement of Nitrogen Runoff Loads During Long Term and Nitrogen Balance in a Tea Field Zone
- Tomihisa Yamamoto, H. Nakasone, Yasuhiro Matsusawa, H. Kuroda, Tasuku Katou
- Chemistry
- 2005
The aim of this study was to estimate the nitrogen balance of the tea field zone. The study area was located in the Makinohara tea field zone, Shizuoka, Japan. The water quality and discharge were… Expand
Continuous Measurements of Fertilizer Components of Effluent Loads from Makinohara Tea Field in Shizuoka
- Tomihisa Yamamoto, H. Nakasone, Yasuhiro Matsusawa, H. Kuroda, Tasuku Katou
- Environmental Science
- 2004
The water quality and discharge from a tea field area in Shizuoka were measured daily and the outflow loads of fertilizer components in runoff water estimated. The results are as follows: The amount… Expand

- Chemistry
- Paddy and Water Environment
- 19 August 2004
Our understanding of nitrogen transformation in paddy fields or wetlands is limited due to the complex interactions between soil, water, and biomass. Therefore, we studied transformation patterns… Expand
