В последнее время в сельском хозяйстве внедряются щадящие технологии, которые минимизируют вмешательство человека в почвенный покров, такие как технологии прямого посева. Часто данные технологии вводятся с элементами биологизации, которые способны дополнительно повышать доступность элементов питания. Однако влияние этих технологий на распределение меди в системе почва-растения сои изучено недостаточно. Целью данной работы являлось сравнение влияния агротехнологий с применением прямого посева (без промежуточных культур, а также с промежуточными яровыми и озимыми культурами) на содержание и распределение меди в почве, корнях и надземной биомассе растений сои.Методы. Исследование проводилось на черноземах выщелоченных в рамках четырех агротехнологий: традиционная обработка, прямой посев, прямой посев с яровыми и с озимыми промежуточными культурами. Отбор проб проводили в июне, июле и сентябре. Содержание меди определяли атомно-абсорбционным методом.Результаты. Концентрация меди в почве, корнях и надземной биомассе сои существенно варьировала в зависимости от срока отбора и примененной агротехнологии. Технологии с элементами биологизации лучше накапливали элемент в определенные периоды роста. Внесение удобрения не оказывало однозначного положительного эффекта, а в варианте с озимыми промежуточными культурами приводило к снижению содержания меди на 10–40%. В сое, выросшей с промежуточными культурами, содержание элемента в июне и июле обычно не ниже, чем для вариантов с традиционной обработкой или обычным прямым посевом.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. Recently, conservation agriculture practices that minimize human intervention in the soil cover, such as direct seeding, have been introduced. These practices are often combined with biologization elements, which can further increase nutrient availability. However, the impact of these practices on copper distribution in the soil-soybean system has been poorly studied. The aim of this study was to compare the impact of direct seeding practices (without intercrops, as well as with spring and winter intercrops) on copper content and distribution in the soil, roots, and aboveground biomass of soybean plants.Methods. The study was conducted on leached chernozems using four different practices: conventional tillage, direct seeding, and direct seeding with spring and winter intercrops. Sampling was conducted in June, July, and September. Copper content was determined using atomic absorption spectroscopy.Results. Copper concentrations in the soil, roots, and aboveground soybean biomass varied significantly depending on the sampling period and the agricultural technology used. Biologization-based technologies accumulated the element better during certain growth periods. Fertilization had no clear positive effect, and in the case of winter cover crops, it led to a 10–40% decrease in copper content. In soybeans grown with cover crops, copper content in June and July was generally no lower than in the case of traditional tillage or direct seeding.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>медь</kwd><kwd>почва</kwd><kwd>соя</kwd><kwd>прямой посев</kwd><kwd>биологизация земледелия</kwd><kwd>промежуточные культуры</kwd><kwd>почвопокровные культуры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>copper</kwd><kwd>soil</kwd><kwd>soybeans</kwd><kwd>direct seeding</kwd><kwd>biologization of agriculture</kwd><kwd>catch crops</kwd><kwd>cover crops</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств субсидии, выделенной Казанскому федеральному университету для выполнения государственного задания в сфере научной деятельности, проект № FZSM-2024-0004</funding-statement><funding-statement xml:lang="en">This research was funded by the subsidy allocated to Kazan Federal University for the state assignment in the sphere of scientific activities, project № FZSM-2024-0004</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">Нафиков М.М., Смирнов С.Г., Краснов А.В., Шашкаров Л.Г.
