Объект исследования - чернозем типичный пахотный (Курская область). Агрегаты были выделены методом мокрого просеивания из насыпного образца верхних 10 см пахотного горизонта после размыва модельным мелководным потоком на большом эрозионном лотке. Из агрегатов, свободно рассыпанных на стекло и закрепленных полиэфирной смолой, были изготовлены шлифы, обработка снимков которых проводилась двумя сравниваемыми способами: Adobe Photoshop + CTan и Thixomet Pro. Большое количество срезов нативных агрегатов под разными углами в среднем сечении позволяет статистически оценить форму агрегатов. Получены данные по морфометрическим показателям агрегатов: фактор формы, степень округлости и коэффициент изрезанности поверхности агрегатов. Оценка сходимости результатов, полученных способом Photoshop + CTan тремя исследователями, проводилась путем сравнения выборок по t-критерию Стьюдента и U-критерию Манна - Уитни. Оценка сходимости усредненных результатов, полученных способом Photoshop + CTan, и результатов, полученных с использованием Thixomet Pro, проводилась по U-критерию Манна - Уитни. Значимых различий между параметрами одних и тех же агрегатов, полученных с помощью сочетания программ Adobe Photoshop и CTan разными исследователями, не обнаружено. Значимых различий между параметрами одних и тех же агрегатов, полученными сравниваемыми способами, не обнаружено. Можно заключить, что достоверность определения морфометрических параметров почвенных агрегатов с помощью Thixomet Pro соизмерима с достоверностью результатов при работе со снимками шлифов в CTan после бинаризации в Adobe Photoshop. Способ получения данных о морфометрических параметрах почвенных агрегатов с помощью Thixomet Pro полностью исключает возможность субъективной ошибки, показывает высокую степень автоматизации, воспроизводимости и достоверности полученных результатов и является более быстрым.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of this study was to investigate the applicability of semiautomatic segmentation methods for obtaining and evaluating morphometric parameters of soil aggregates in artificially prepared loose samples in soil thin sections. The object of the research is typical arable Chernozem. The aggregates were separated by wet sieving method from loose sample of upper 10 cm of the plowing horizon after erosion by a model shallow water flow on a large erosion tray. The aggregates, loosely scattered on the glass and fixed with polyester resin, were used to produce the thin sections. Images of the thin sections were taken under a polarizing microscope and then were processed using two methods compared: Adobe Photoshop + CTan and Thixomet Pro. Data on morphometric parameters of aggregates were obtained: the shape factor, the degree of roundness and the coefficient of aggregate surface roughness. The convergence of the results obtained using Photoshop + CTan by three researchers was evaluated by comparing samples using the Student's test and the Mann-Whitney test. The convergence of the averaged results obtained using Photoshop + CTan and the results obtained using Thixomet Pro was evaluated using the Mann - Whitney test. No significant differences were found between the parameters of the same aggregates obtained using a combination of Adobe Photoshop and CTan programs by different researchers. No significant differences were found between the parameters of the same aggregates obtained by the compared methods. So, one can conclude that the reliability of determining the morphometric parameters of soil aggregates using Thixomet Pro is comparable to the reliability of results when working with images of sectionsin CTan after binarization in Adobe Photoshop. The method of obtaining data on morphometric parameters of soil aggregates using Thixomet Pro completely eliminates the possibility of subjective error, shows a high degree of automation, reproducibility and reliability of the results obtained, and is faster.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бинаризация снимков</kwd><kwd>морфометрия агрегатов</kwd><kwd>чернозем</kwd><kwd>CTan</kwd><kwd>Thixomet Pro</kwd></kwd-group><kwd-group xml:lang="en"><kwd>image binarization</kwd><kwd>morphometry of aggregates</kwd><kwd>Chernozem</kwd><kwd>CTan</kwd><kwd>Thixomet Pro</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке гранта Президиума РАН “Теоретические и экспериментальные исследования для эффективного научно-технического развития агропромышленного комплекса Российской Федерации”</funding-statement><funding-statement xml:lang="en">The research was supported by a grant from the Presidium of the Russian Academy of Sciences “Theoretical and experimental studies for the effective scientific and technical development of the agro-industrial complex of the Russian Federation”</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Вадюнина А.Ф., Корчагина З.А.
