“…Для компенсации дефицита железа в почве используют его водорастворимые неорганические соли и хелаты. Последние позволяют не только восполнить запас железа в почве, но и обогатить растениеводческую продукцию микроэлементами, улучшить фитосанитарное состояние посевов [7,8,9,10].…”

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.

Plant growth regulators have a wide spectrum of physiological activity. Thanks to their action, resistance of soybean plants to adverse environmental factors, diseases, growth, development and quality is observed. Soy is the most widely used oilseed in the world. The world annual production of soybeans exceeds 260 million tons. It is the main edible plant and the main source of vegetable protein worldwide.The global demand for soybeans is constantly growing as its seeds provide essential proteins, oils and nutraceuticals. In an effort to meet the increased demand for this crop, it has become necessary to introduce cultural practices that promote adaptation to difficult environmental conditions, can improve soybean tolerance to abiotic stress and increase yields. Plant growth regulators are mainly used for this purpose due to their critical role in plant growth and development. One of the main growth regulators are such phytohormones as: auxins, gibberellins, cytokinins, brassinolides, ethylene, abscisic and jasmonic acid. Each of the groups of phytohormones produces its own characteristic action, which is similar in plants of different species. Cell division and elongation, which underlie all processes of growth and morphogenesis, are under the control of auxins and cytokines in plants, so their complete absence can lead to death. These compounds generally have a positive effect on the morphology, physiology and quality of the soybean crop. They are also able to regulate and control to a large extent the processes of growth and differentiation of plant cells. It should be noted that these phytohormones are required in small amounts for the activation and regulation of morphogenetic processes in soybean and other agricultural plants.
