Abstract

This paper presents the results of studies on soil carbon stock dynamics, CO₂ emission, and soil microbial respiration during post-industrial succession upon reforestation of a sand–gravel quarry in southern Karelia. In July 2021 and 2022, soils in the areas with different reforestation practices were studied. In 1991, one-year-old Scots pine (Pinus sylvestris L.) seedlings were planted on the plots with (1) sandy–gravelly mineral soil (sample plots SP 1 and SP 2) and (2) soil with added peat (SP 3). Native podburs (Entic Podzols) under undisturbed lingonberry pine forest (SP 4) were used as the control. We determined the total (organic) carbon, the microbial activity (using the basal and substrate-induced respiration methods in laboratory), and the CO₂ emission from the soil surface (in the field). The assessment of the properties of post-industrial soils indicated that the studied parameters in replantozem on SP 3 were close to those in the podzolized podbur on SP 4, which attested to a positive effect of peat-enriched substrate on the soil and plant recovery in the abandoned quarry. Considerably higher values of carbon stocks (by 6–10 times) and CO₂ fluxes (by 2–4 times) in the replantozem (Umbric Leptosols (Novic)) on SP 3 in comparison with psammozems (Skeletic Leptosols) on SP 1 and SP 2 were due to intensive organic matter accumulation and the application of peat substrate rich in nutrients and plant diaspores during planting. Soil carbon stocks, CO₂ emission, microbial activity, and stand productivity at SP 1 and SP 2 were lower than those at SP 3 and SP 4. To make more accurate predictions of the dynamics of the analyzed parameters of disturbed soils, it is necessary to take into account their spatial and temporal variability.

森林开垦对南卡累利阿自然生态系统和技术生态系统土壤碳储量和呼吸作用的影响

摘要本文介绍了对卡累利阿南部沙砾石采石场重新造林后工业化演替期间土壤碳储量动态、二氧化碳排放和土壤微生物呼吸的研究结果。2021 年 7 月和 2022 年 7 月，对采用不同造林方法的地区的土壤进行了研究。1991 年，一岁大的苏格兰松树（Pinus sylvestris L.）幼苗被种植在（1）沙砾矿质土壤（样本地 SP 1 和 SP 2）和（2）添加泥炭的土壤（样本地 SP 3）上。未受干扰的越橘松林下的原生豆荚（Entic Podzols）（SP 4）作为对照。我们测定了土壤中的总（有机）碳、微生物活性（在实验室中使用基质呼吸法和基质诱导呼吸法）以及土壤表面的二氧化碳排放量（在田间）。对工业化后土壤特性的评估表明，在 SP 3 上的 replantozem 中研究的参数与 SP 4 上的 podzolized podbur 中的参数接近，这证明泥炭富集基质对废弃采石场的土壤和植物恢复有积极作用。与 SP 1 和 SP 2 上的荚果壤土（骨质壤土）相比，SP 3 上的 replantozem（Umbric Leptosols (Novic)）中的碳储量（6-10 倍）和二氧化碳通量（2-4 倍）要高得多，这是因为在种植过程中积累了大量有机物质，并施用了富含养分和植物二孢子的泥炭基质。SP 1 和 SP 2 的土壤碳储量、二氧化碳排放量、微生物活性和林分生产力均低于 SP 3 和 SP 4。为了更准确地预测受干扰土壤的分析参数动态，有必要考虑其空间和时间变化。

期刊介绍： Eurasian Soil Science publishes original research papers on global and regional studies discussing both theoretical and experimental problems of genesis, geography, physics, chemistry, biology, fertility, management, conservation, and remediation of soils. Special sections are devoted to current news in the life of the International and Russian soil science societies and to the history of soil sciences. Since 2000, the journal Agricultural Chemistry, the English version of the journal of the Russian Academy of Sciences Agrokhimiya, has been merged into the journal Eurasian Soil Science and is no longer published as a separate title.
