Дана оценка изменения их химической структуры в денудационно-аккумулятивном ландшафте. Выявлено, что подавляющая часть водоустойчивых свободных микроагрегатов в эрозионной зоне – фрагменты/осколки разрушенных (преимущественно), а также новообразованных макроагрегатов за счет динамического замещения органического вещества in situ, о чем явно свидетельствуют интегральные показатели химической структуры всех пулов органического вещества свободных микроагрегатов эродированного агрочернозема, по сравнению с таковыми полнопрофильного варианта: пониженные индексы разложенности (DI), ароматичности (ARI) и гидрофобности (HI). Аналитические данные свидетельствуют в пользу преобладающей транспортировки из эрозионной зоны микроагрегатов, представленных фрагментами разрушенных (преимущественно) и новообразованных макроагрегатов. Во время транспортной фазы ранее физически защищенное агрегированное органическое вещество свободных микроагрегатов подвергается частичной деградации. Минерализуется преимущественно наиболее лабильная его часть (гидролизуемая), а его стабильная часть остается мало-/неизмененной. Минерально-ассоциированное органическое вещество (ил и остаток) мало или совсем не трансформируется.</p></abstract><trans-abstract xml:lang="en"><p>The chemical structure of organic matter (OM) pools within water-stable free microaggregates, isolated from air-dry aggregates (2–1 mm) in arable horizons of non-eroded, eroded and deposited agrochernozems has been studied by solid-state 13C-NMR spectroscopy. An assessment is made of the alteration of their chemical structure in the denudative-accumulative landscape. It was revealed that the overwhelming majority of water-stable free microaggregates in erosion zone are the fragments of destroyed macroaggregates, mainly newly formed due to the dynamic replacement of OM in situ. This is clearly evidenced by the integral indicators of the chemical structure of all OM pools in free microaggregates of eroded agrochernozem compared to those of the non-eroded one: reduced OM decomposition index (DI), OM aromaticity index (ARI) and OM hydrophobicity index (HI). Analytical data indicate the predominant transport from the erosion zone of microaggregates, represented by fragments of destroyed and mainly newly formed macroaggregates. During the transport phase, the previously physically protected occluded OM of free microaggregates undergoes partial mineralization. Predominantly its most labile part (hydrolysable) is mineralized, and its stable part remains little/non-changed. Mineral-associated OM (Clay and Residue) changes little, maintaining relative freshness.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эрозия</kwd><kwd>водоустойчивые свободные микроагрегаты</kwd><kwd>химическая структура органического вещества</kwd><kwd>CP-MAS 13C-ЯМР-спектроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>erosion</kwd><kwd>water-stable free microaggregates</kwd><kwd>chemical structure of organic matter</kwd><kwd>CP-MAS 13C-NMR spectroscopy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования проведены в рамках Госзадания FGUR–2022–0012 с привлечением  оборудования  Центра  коллективного  пользования “Функции и свойства почв и почвенного покрова” Почвенного института им.
