Stan mikoryz sosny zwyczajnej w uprawie założonej na gruncie porolnym

The quantitative and qualitative analysis of mycorrhizae was done for Scots pine in plantation established on post−agricultural land. The state of mycorrhizae depended on the applied method of soil preparation (full deep ploughing, full ploughing with subsoiling, full shallow ploughing and ridge formation) as well as the presence and density of introduced land improving species (5, 3, 1.5 thousand/ha).
