摘要

Long‐term mowed sward ecosystems are the least affected anthropogenicaly.Soil under sward ecosystems is not tilled and the influence of agricultural implements is only superficial.Mineral fertilisers not only increase the productivity of sward phytocenosis (Daugeliene, 2002 ; Butkuviene,Butkute,2004), but also result in changes of soil chemical properties and biogenic elements migration to deeper soil layers (Daugeliene,2002 ;Gutauskas,Slepetiene,2002).Little information has been available in Lithuania so far on the processes which occur in sward ecosystem soils and influence soil chemical indicators under fertilisation with natural substances.Considerable attention has to be paid to : (1 ) the amounts of biogenic elements, which influence soil chemical properties ; (2) the productivity of sward phytocenosis.
