Исследовано влияние фильтрации воды во время паводка, биовыноса и радиоактивного распада 137Cs на процесс миграции в почве. Вклад радиоактивного распада, фильтрации воды и биовыноса в общий вынос 137Cs из почвы составил за период с 1994 г. по 2007 г. соответственно 50–79, 20–50, 0.3–2.2 % в зависимости от способа обработки, дозы минерального удобрения и соотношения в ней элементов питания. Установлено, что повышенный вынос 137Cs из слоя почвы поймы при проведении двухъярусной вспашки, по сравнению с дискованием и естественным травостоем, определяется более низким значением числа Пекле, что свидетельствует о преобладании конвективного переноса 137Cs, по сравнению с диффузионным, в общем потоке раствора.</p></abstract><trans-abstract xml:lang="en"><p>This paper examines the patterns of 137Cs migration in the alluvial soil of the central floodplain of the Iput River (Novozybkovsky district, Bryansk region). The effect of water filtration during flooding, bioremoval by plants and 137Cs radioactive decay on the migration process of Cs ions in the soil was studied. The contribution of radioactive decay, filtration of water and bioremoval to the total removal of 137Cs from the soil during the period from 1994 to 2007 was 50–79, 20–50, 0.3–2.2 % coorespondingly, depending on the treatment method, the dose of mineral fertilizers and the ratio of nutrients. It was found that the increased removal of 137Cs from the soil layer of the floodplain during double-depth plowing, compared with disking and natural grass stands, is determined by a lower Peclet number, which indicates the prevalence of convective 137Cs transfer in contrast to diffusion in the total solution flow.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>137Cs</kwd><kwd>миграция</kwd><kwd>закономерность</kwd><kwd>радиоактивный распад</kwd><kwd>биовынос</kwd><kwd>фильтрация воды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>137Cs</kwd><kwd>migration</kwd><kwd>regularity</kwd><kwd>radioactive decay</kwd><kwd>biocarrying out</kwd><kwd>water filtration</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Борздыко И.А.
