The aim of the study was to investigate the effect of soil recovery after a landslide on the nutritional status of a young generation of Silver fir (Abies alba Mill.) and Silver birch (Betula pendula Roth.) trees. The study was carried out on the site of a landslide that took place in 2010 in the Gorlice Forest District (Southern Poland). Basic soil properties, macro, and microelements content and enzymatic activity were determined in the soil samples that were collected from across the landslide area, from locations distributed by a grid 10 × 10 m (18 points). Plant material samples, collected to indicate nutritional status, were also taken from each point. Results demonstrate that the nutritional status of emerging regeneration depends on soil acidification and soil organic matter content. The pH of the soils on the landslide determines the intensity of nutrient uptake by the young seedlings. The nutrition of young trees varied across the landslide zone, differing in terms of the soil’s organic matter content and its chemical properties. In comparison to the depletion zone, the accumulation zone proved to be substantially richer in soil organic matter, resulting in higher soil biochemical activity. The study demonstrates that Silver birch (Betula pendula Roth.) is improving nutrient cycling in areas disturbed by landslide.

滑坡恢复现场树木幼苗的营养状况

这项研究的目的是调查滑坡后土壤恢复对银杉（Abies alba Mill。）和白桦（Betula pendula）的年轻一代的营养状况的影响。罗斯）。这项研究是在2010年在戈里斯森林区（波兰南部）发生的滑坡现场进行的。确定了土壤样品的基本土壤性质，宏量和微量元素含量以及酶活性，这些样品是从整个滑坡区收集的，并由10×10 m的网格分布（18个点）。还从每个点采集了植物材料样品，以表明其营养状况。结果表明，新兴再生的营养状况取决于土壤酸化和土壤有机质含量。滑坡上土壤的pH值决定了幼苗幼苗吸收养分的强度。在整个滑坡区，幼树的营养各不相同，其土壤有机质含量及其化学性质也各不相同。与枯竭区相比，积累区被证明实质上富含土壤有机质，从而提高了土壤生化活性。研究表明，白桦（Betula pendula Roth。）正在改善受滑坡影响的地区的养分循环。
