Tsandekova, O.
The article analyzes the results of the total ash content in leaf litter of Acer negundo L., taking into account the influence of its phytogenic zones, in conditions of disturbed floodplain communities. Sampling was carried out at survey sites under various conditions of crowns, taking into account the zones of influence of trees during the growing season (from May to September). Determination of ash content was performed by dry ashing. The research results were processed statistically using Microsoft Office Excel 2007. It was revealed that in the litter of Acer negundo there is the greatest accumulation of the ash component in the subcrown and near-front zones in single trees in not close forest stands, in comparison with other groups of trees and with control. Seasonal dynamics of ash content of top humus maple reveals some quantitative changes depending on the conditions of a specific habitat, which is most clearly traced in the final stage of the vegetative period. Experimental data can be used in assessing the state of the ground cover and the structure of the phytocenosis.
