В статье представлены результаты оценки влияния хелатных комплексов трехвалентного железа с диэтилентриаминпентауксусной (ДТПА Fe) и этилендиаминтетрауксусной (ЭДТА Fe) кислотами на подвижность и доступность железа для растений в почве c реакцией среды, близкой к нейтральной. В модельном опыте с использованием дренажных колонок установлены закономерности распределения железа в толще почвы и его вынос с поливными водами из прикорневой зоны растений (10 см). На фоне однотипного распределения железа в почве отмечали более высокое содержание его подвижных форм в нижних слоях при использовании ЭДТА Fe. Выщелачивание железа из почвы отмечалось как при использовании ДТПА Fe, так и ЭДТА Fe. В условиях вегетационного опыта изучено влияние хелатных форм на накопление железа в растениях ячменя (Hordeum vulgare L.) в период их начального роста (11 суток). Содержание железа в побегах варьировало от 120 до 140 мкг/г, в корнях – от 233 до 244 мкг/г, при содержании в контрольном образце 200 мкг/г. Наибольшее накопление железа в проростках отмечали на уровне корневой системы в варианте опыта с ЭДТА Fe. Данные по накоплению железа в корнях ячменя коррелировали (r = 0,99) с данными по их зольности.</p></abstract><trans-abstract xml:lang="en"><p>In spite of well-known mechanisms of iron consumption by plants from the soil and action patterns of iron ions in the soils, the work to eliminate the deficiency of this trace element in plants is still relevant. The article presents an assessment of the effect of iron (III) chelate complexes with diethylenetriaminepentaacetic acid (DTPА Fe) and ethylenediaminetetraacetic acid (EDTA Fe) on the mobility and availability of iron for plants in soil with a pH close to neutral.  In a model experiment with using of drainage columns, there were established the patterns of iron distribution in the soil and its removal with irrigation water from the root zone of plants (10 cm). Against the background of similar distribution of iron in the soil, a higher content of its mobile forms in the lower layers was noted when using EDTA Fe. The leaching of iron from the soil was confirmed using both DTPA Fe and EDTA Fe. The vegetation experiment revealed the effect of chelate forms on the accumulation of iron in barley plants (Hordeum vulgare L.) during their early growth period (11 days). The iron content in the shoots varied from 120 to 140 µg/g, in the roots – from 233 to 244 µg/g, with a content of 200 µg/g in the control sample. A significant  contribution to the accumulation of iron in barley seedlings was observed at the level of the root system in the experiment with EDTA Fe. Data on the accumulation of iron in barley roots were correlated (r = 0.99) with data on their ash content.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>железо</kwd><kwd>хелатный комплекс</kwd><kwd>диэтилентриаминпентауксусная кислота</kwd><kwd>этилендиаминтетрауксусная кислота</kwd><kwd>мобильность</kwd><kwd>дренажная колонка</kwd><kwd>выщелачивание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>iron</kwd><kwd>chelate complex</kwd><kwd>diethylenetriaminepentaacetic acid</kwd><kwd>ethylenediaminetetraacetic acid</kwd><kwd>mobility</kwd><kwd>drainage column</kwd><kwd>leaching</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена без финансового обеспечения в рамках инициативной тематики.
