Accumulation and carrying over of nutrients and heavy metals by soybean plants on the soils of Far Eastern south

The paper reports the features of accumulation and carrying of potassium, copper, and chromium by soy-bean plant on two types of soils in the experiments with long-term use of mineral and organic fertilizers in Amurskaya oblast and Primorsky region. Chromium showed acropetal distribution in soybean plant, i.e. the bulk of this element is accumulated in roots, so the carrying over of this element with harvest is not great. Copper demonstrates basipetal distribution, and it is accumulated mostly in seeds and leaves and a bit fewer amounts in roots and straw. As a rule, carrying over of copper with harvest is more than 60%, so this element should be considered among the agrochemically active ones; evacuation of such elements exceeds return significantly. Potassium occupies an intermediate position and belongs to mid-active elements.
