Changes in Soil Features and Phytomass during Vegetation Succession in Sandy Areas

This research was conducted on an area of inland sands characterised by various degrees overgrowth vegetation and soil stabilisation. landscape’s origin is not natural but connected to human industrial activities dating from early medieval times, which created a powerful centre for mining metallurgy. study aims identify the changes in above- belowground phytomass initial stages succession their influence chemical properties morphology soil. It found that Salix arenaria dominated primary production all plots tested. The amounts this species each community were as follows: 8.55 kg/400 m2 (algae–mosses), 188.97 (sand grassland–willow), 123.44 (pine–willow–mosses), 14.63 grassland–mosses–willow), 196.55 (willow–pine–sand grassland). A notable share Koeleria glauca Plots IV (45.73 kg) V (86.16 kg). Basic (pH, Corg, Nt), available plant elements (P), nutrients (Ca, Mg, K, P, Fe) beneath dominant examined. Soil acidity (pH) varied greatly, ranging acidic (pH = 3.2) weakly 6.3). content organic carbon (Corg) individual humus horizon ranged 0.28% 1.42%. maximum contents total nitrogen (O) organic-humus (OA) horizons. highest Pavail horizons, 10.41 65.23 mg/kg, mineral horizons under K. (24.10 mg/kg) acutifola (25.11 mg/kg). features differently across sites, representing different succession.
