Evaluation of Soil Loss Tolerance and Tree Growth Features Based on Planting Ground Methods in the Alpine Center, Degraded Forestland in the Republic of Korea

The Jeongseon Alpine Center, a degraded forestland, has very unique soil feature as it was filled with cut from the nearby area and not yet been rehabilitated since end of 2018 Winter Olympics. Therefore, this study attempted to identify way establish stable efficient planting groundwork successfully restore distinctive region. Six different groundworks, control, biochar, leaf-mold, mulching, tillage, polyacrylamide treatments were constructed in September 2020. Soil-related indices have tracked while growth physiological responses planted Pinus densiflora (Pd) Larix kaempferi (Lk) seedlings monitored until May 2022. Mulching had 2–4 times average SWC when compared control. Simultaneously, there least variation temperature change, total loss only 0.05 ton/ha. Similarly, leaf-mold relatively high SWC, fertility increased, 6.37 tons/ha, indicating trend line biochar. Pd highest Amax, E, gs, Jmax. Furthermore, following mulching showed second-highest photosynthetic general, height DRC also demonstrated favorable results above two treatments. 1.6 2.2 higher than control group PIabs PItotal, which represent vitality, so impact on environmental stress thought be less that leaf-mold. Lk greatest responses, Nonetheless, rather low Pd, no discernible differences across As result, considerable effect method could demonstrated. case best response. Nevertheless, terms maintenance for slope stability, is assessed most ideal method.
