摘要：This research was conducted on an area of inland sands characterised by various degrees of overgrowth by vegetation and soil stabilisation. This landscape’s origin is not natural but is connected to human industrial activities dating from early medieval times, which created a powerful centre for mining and metallurgy. This study aims to identify the changes in the above- and belowground phytomass in the initial stages of succession and their influence on the chemical properties and morphology of the soil. It was found thati Salix arenaria /idominated in primary phytomass production in all plots tested. The amounts of this species found in each community were as follows: 8.55 kg/400 msup2/sup (algae–mosses), 188.97 kg/400 msup2/sup (sand grassland–willow), 123.44 kg/400 msup2/sup (pine–willow–mosses), 14.63 kg/400 msup2/sup (sand grassland–mosses–willow), and 196.55 kg/400 msup2/sup (willow–pine–sand grassland). A notable share of iKoeleria glauca/i was found in the phytomass production of Plots IV (45.73 kg) and V (86.16 kg). Basic soil properties (pH, Csuborg/sub, Nsubt/sub), available plant elements (P), and plant nutrients (Ca, Mg, K, P, Fe) beneath the dominant plant species were examined. Soil acidity (pH) varied greatly, ranging from acidic (pH = 3.2) to weakly acidic (pH = 6.3). The content of organic carbon (Csuborg/sub) in individual plots beneath the dominant species in the humus horizon ranged from 0.28% to 1.42%. The maximum contents of organic carbon and total nitrogen were found in organic (O) and organic-humus (OA) horizons. The highest Pavail content was found in organic and organic-humus horizons, ranging from 10.41 to 65.23 mg/kg, and in mineral horizons under iK. glauca/i (24.10 mg/kg) and iSalix acutifola/i (25.11 mg/kg). The soil features and phytomass were varied differently across individual sites, representing different stages of succession.
