Autor: Noriko Takigawa, Masato Kuwahara, Syunji Takanishi, Ken-ichiro Ogawa, Takao Tamura

Publikováno v: Journal of Japan Society of Civil Engineers, Ser. B1 (Hydraulic Engineering). 67:I_571-I_576

This study conducted runoff analysis for the floods in Sep. 1954 and Oct. 2004 by the distributed runoff model for Yanase Dam basin in the upper Douzangawa River, where once become devastated by an operation of Besshi copper mine and recovered by aff

Study on the scarcity of red tide in the eutrophicated waters of Ariake Bay. III. Conversion of AlPO4-P to Fe-bound P in sea sediments

Autor: Shinya Ishio, Masato Kuwahara, Hisaki Nakagawa

Publikováno v: NIPPON SUISAN GAKKAISHI. 52:901-911

Fe-bound P in the sediment was suspected to be the cause of the frequent red tide in Hakata Bay in summer, because it releases PO43- into the upper water when H2S is generated in the sediment. Thus, the contents of Fe-bound P were measured by applyin

Effect of pod removal on dinitrogen fixation of soybean plants differing in growth habit

Autor: Shoitsu Ogata, Kounosuke Fujita, Masato Kuwahara

Publikováno v: Soil Science and Plant Nutrition. 35:245-255

Eight cultivated soybean varieties (Glycine max l. Merr.) and one wild soybean variety (Glycine soja Sieb. and Zucc.) differing in their growth habit, i.e. determinate and indeterminate types were grown in the field. The effects of pod removal on the

Supplemental nitrogen fertilizer to soybeans. II. Effect of application rate and placement on seed yield and protein yield

Autor: Masato Kuwahara, Iwao Watanabe, Takayuki Higashi, Hiroshi Naganoma, Kousei Tabuchi, Yutaka Hirata, Hiroshi Nakano

Publikováno v: Japanese Journal of Crop Science. 56:329-336

Nitrogen fertilizer as ammonium sulfate was applied to soybeans [Glycine max (L.) Merrill cv. Bonminori and Enrei] at flowering stage to examine effects of application rate and placement on seed yield and protein yield. Seed yield of "Bonminori" was

Natural15N Abundance of Field Grown Soybean Grains Harvested in Various Locations in Japan and Estimate of the Fractional Contribution of Nitrogen Fixation

Autor: Toshikazu Takahashi, Masato Kuwahara, Junji Ishizuka, Iwao Kambayash, Tadakatsu Yoneyama, Hiroshi Nakano

Publikováno v: Soil Science and Plant Nutrition. 32:443-449

Natural 15N concentrations (δ15N values by per mil relative to atmospheric nitrogen) of soybean grains and soils from various locations in Japan were analyzed by a ratio mass spectrometer. The δ15N values of nonnodulating plants showed considerable
