Рассматривать фосфор как “неподвижный” элемент почвы не вполне корректно, поскольку его соединения могут активно перераспределяться в ходе эрозионных процессов. Результаты проведенного исследования показали, что участки аккумуляции почвенных частиц не являются участками аккумуляции фосфора. В работе были изучены различные формы фосфора в дерново-подзолистой почве, приуроченной к разным элементам склона. Установлено, что подвижные, минеральные и валовые формы фосфора преимущественно накапливаются в верхней части склона. При продвижении вниз по склону их содержание достоверно снижается, при этом статистически значимые различия между почвами нижней части склона и его подножия не выявлены (p &gt; 0.05). Анализ водопрочных агрегатов позволил заключить, что основной причиной выноса фосфора является водный режим исследуемых позиций склона. В воздушно-сухих агрегатах разных размерных фракций содержание подвижного и валового фосфора существенно не различается. Агрономически ценные агрегаты (размером 2–5 мм в диаметре) преимущественно накапливают минеральный фосфор. Следовательно, они играют ключевую роль в аккумуляции минеральных малоподвижных соединений фосфора. </p></abstract><trans-abstract xml:lang="en"><p>Redistribution of phosphorous is very important problem. Naming phosphorous “immobile” soil element is inaccurate, because it easily washing away due to erosion proses. In our research we observed, that the point of soil particles accumulation are not points of phosphorous accumulation. We examined different forms of phosphorous in soil: mobile, mineral, organic and total. Mobile phosphorous, mineral phosphorous and total phosphorous mostly accumulated at the top of the slope. Down the slope, their content decreases considerably, without significant differences between the soil at the slope and at the foot of the slope (p-value &lt; 0.05). Moreover, the examination of waterstable aggregates leads to the conclusion, that water-regime on the slope and in the bottom of the slope is the main reason of phosphorus removal. The airdry different sized aggregates mostly contain approximately equal amounts of mobile and total phosphorous. They are aggregates measuring 5–2 millimeters in diameter which predominantly accumulate mineral phosphorus, so agronomically valuable aggregates play the key role in mineral immobile phosphorous compounds accumulation.  </p></trans-abstract><kwd-group xml:lang="ru"><kwd>дерново-подзолистые почвы</kwd><kwd>углерод органических соединений</kwd><kwd>подвижный фосфор</kwd><kwd>минеральный фосфор</kwd><kwd>валовый фосфор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Albeluvisols</kwd><kwd>organic carbon</kwd><kwd>mobile phosphorous</kwd><kwd>mineral phosphorus</kwd><kwd>total phosphorous</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">Аринушкина Е.В.
