Liming of high acid forest soils of acid ecological series is considerably questionable from some points of view. Expressive soil`s buffer of zones Fe3+ and Al3+ is formed from accumulation of forest raw floor and single organic fractions. Adjustment of soil reaction is short-term and temporarily high content of Mg can create antagonism in case of plant nutrition by other basic. Expressive mineralization has ability to invoke nutritive imbalance in case of oversize liming of mor humic forms and it is followed in many cases by claims caused by climatic stresses. Stands in stage of young-growth stands suffer from nitrogen deficit in nutrition in areas with overall adjustment of forest soil in higher locations of the Ore Mts. and expressive reduction of development of initial stage of humus form.
