The rice yield of this non-fertilized field has been remarked keeping about 70% of that of ordinarily fertilized fields. Continuous irrigation is the particularity of the production practices in this field. The experimental results are summarized as follows. 1) The total nitrogen of the soil was determined as 130 mg N of mean value per 100 g soil. The diminishing tendency of total nitrogen of soil could not been observed accompanying with the investigation years. The total nitrogen values widely varied in the growing season of rice plant (38.8% variation coefficient), and were higher at inlet part and lower at the outlet of the paddy field. 2) Water soluble nitrogen of the soil were less than 0.6% of the total nitrogen, and almost of them were NH_4-N form. One normal HC1 solution soluble soil nitrogen content was mostly equal to that of the rice plants. 3) Everywhere in this field, water soluble phosphate of the soil was found at higher contents in early stage of rice plant growing, and lower in the late stage. One normal HC1 solution soluble phosphate contents of the soil decreased rapidly at the early July. 4) Ammonium-nitrogen and phosphate contents of the irrigation water were 0.29 ppm and 0.09 ppm on averages, respectively. The contents of nutrients in the flooded water of this field decreased with distances from the inlet. 5) The above mentioned decreases of nutrients in the flooded water were remarkably at the gland period of rice growing, especially for Ca, NH_4-N and P_2O_5 contents. 6) The released Ca concentration into deionized water was affected rather by the soil water ratio than by extraction time factor. Calcium adsorption of the soil differed from anions of calcium salts. Much higher calcium adsorption ratio of the soil were observed by three folded a mnnentratinn treatment tn irrioatinn water.[著者抄録]本報告は長期の無施肥無農薬栽培(28年継続)の水田土壌における二三の植物栄養分の動態を四年間調査研究した結果である。当該水田における水稲の収量は施肥による通常栽培に対して7割近くに安定化して未ているといわれ,その栽培での特徴は灌がい用水を可能な限り掛け流しにすることである。調査検討した点は以下のように要約することができる。1.無施肥田土壌中の全窒素は,1OOg土壌当り平均130mgNを示し,年々減少傾向を認められない。また,その全窒素量は、水稲の生育時期においても変動し,その大きさは,38.8%の変動係数として示すことができた。なお,水田内の調査位置によっては,水口部で高く,水尻部で低い値を示した。2.無施肥田上壌の水溶性窒素は,全窒素の0.6%未満で,大部分はアンモニア態窒素であった。さらに一規定塩酸溶液可溶アンモニア態窒素は,サンプル時期によって変動があるが,水稲の生育旺盛期においてはいずれの位置においても作物体内の窒素量に匹敵する場合が多い。3.これらの土壌の水溶性リン酸量は水稲の生育初期に多く,後期に減少する傾向を示した。一規定塩酸可溶性リン酸量は、同処理のアンモニア態窒素よりも多量の場合が多く,7月上旬から急激な減少傾向を示した。4. 7月初句に無施肥田に流入する灌がい水中のアンモニア態窒素は0.29ppm,リン酸は0.09ppmの平均値を示し,純農村型灌がい水としては窒素,リン酸,ケイ酸, Mg, Kなどは多少高く,Caは低い値を示した。無施田の水口より水尻に向って用水中の諸成分量は減少傾向を示した。これは無施肥田内の水口域あるいは上流域で諸成分の沈降,吸着,水稲による吸収などを明らかに示すものである。5.水口より水尻へ流連する用水中の成分量の減少は,水稲生育の盛んな時期に顕著であり,また,Me, K, NaなどよりCa,NH_4-N,P_20_5などで著るしい減少が示された。6.無施肥田土壌より溶出するCa量は時間の要因より,土壌溶液比の違いによる影響が大きい。土壌のCaの吸収量は対応する溶存アニオンの違いによって異なった。灌がい水中の3倍量のCa濃度処理では,いずれのカルシウム塩処理においてもCaの吸収割合は著しく増加した。","subitem_description_type":"Abstract"}]},"item_2_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"記念特集I","subitem_description_type":"Other"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学農学部"}]},"item_2_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04538889","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kawamura, Saburo"},{"subitem_text_language":"en","subitem_text_value":"Nakajima, Teruo"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学農学部農芸化学科土壌学研究室"},{"subitem_text_value":"近畿大学農学部農芸化学科土壌学研究室"}]},"item_2_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Laboratory of Soil Science, Department of Agricultural Chemistry, Faculty of Agriculture, Kinki University"},{"subitem_text_value":"Laboratory of Soil Science, Department of Agricultural Chemistry, Faculty of Agriculture, Kinki University"}]},"item_2_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"川村,  三郎"},{"creatorName":"カワムラ, サブロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中島,  照夫"},{"creatorName":"ナカジマ, テルオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-18"}],"displaytype":"detail","filename":"AN00064044-19790315-0157.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00064044-19790315-0157.pdf","url":"https://kindai.repo.nii.ac.jp/record/5102/files/AN00064044-19790315-0157.pdf"},"version_id":"8da3ff7a-88b3-4d23-9e7c-e67d1e5fcfe1"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_thumbnail":{"attribute_name":"サムネイル","attribute_value_mlt":[{"subitem_thumbnail":[{"thumbnail_label":"AN00064044-19790315-0157.jpeg","thumbnail_url":"/api/files/4e77c75f-9b28-4810-ba27-bd8283592429/AN00064044-19790315-0157.jpeg?versionId=cfa0e24f-9adf-4a36-9fea-0954fe5970ba"}]}]},"item_title":"長期無施肥水田土壌における二三の植物養分の動態について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"長期無施肥水田土壌における二三の植物養分の動態について"},{"subitem_title":"On the Some Plant Nutrients Behavior in Many Years Non-fertilized Paddy Soil","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["1453","3069"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-29"},"publish_date":"2008-01-29","publish_status":"0","recid":"5102","relation_version_is_last":true,"title":["長期無施肥水田土壌における二三の植物養分の動態について"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T19:33:30.375636+00:00"}
