Agro-development of northern territories results in radical transformation of soils of these ecosystems. On the example of Nadym district (N 65.5; E 72.6) of Yamal-Nenets Autonomous Okrug (Russia) it is shown that the process of agrogenic transformation of reference podzols is similar to the process of formation of Plaggen soils, which were repeatedly found in Northern Europe and other regions (Plaggen Anthrosols – result of Plaggen Management). As a result of the application of large amounts of organic substrate (Plaggen Material), the thickness of the surface horizons increases considerably (from 3 cm to more than 30 cm in some cases). These soils occupy an intermediate position from reference soils to highly transformed − Hortic/Plaggic Podzols. Hortic and Plaggic horizons are characterized by reduced acidity (pH H2 O 5–6, pH CaCl2 4–5), increased content and stock of organic carbon (5.4–14.5 %). Soils of agrogenic and postagrogenic ecosystems are characterized by relatively high content of basic nutrients (P-P2 O5 up to 386 mg kg−1 , K-K2 O up to 239.0 mg kg−1 ) and clay (up to 20.9 %), also the degree of their microstructure increases in comparison with reference Podzols of Nadym district. The taxonomic composition of soil microbiome also changes greatly in the process of agricultural development of soils. In reference Podzols Proteobacteria , Actinobacteria and Bacteroidetes dominate. In general the microbiological profile in the of agrogenic and postagrogenic soils shifts towards the increase of the phyla Proteobacteria , Acidobacteria , Planctomycetes , Nitrospirae , Verrucomicrobia (for abandoned lands) and Actinobacteria , Bacteroides , Firmicutes , Euryarchaeota (for soil in use).

以亚马尔地区中部(西西伯利亚)为例,低温生态系统中土壤的地质、肥力和微生物组多样性的 Agropedogenesis 及其相关变化
北部地区的农业发展导致这些生态系统的土壤发生根本性的变化。以 Nadym 区 (N 65.5;E 72.6) 的 Μ� 研究表明,参考灰化土的农业转化过程类似于在北欧和其他地区反复发现的 Plaggen 土壤的形成过程(Plaggen Anthrosols – Plaggen 管理的结果)。由于应用了大量的有机基材(Plaggen 材料),表面层的厚度大大增加(在某些情况下从 3 厘米增加到 30 厘米以上)。这些土壤占据了从参考土壤到高度转化的 - Hortic/Plaggic Podzols 的中间位置。Hortic 和 Plaggic 层的特点是酸度降低 (pH H2O 5–6, pH CaCl2 4–5),有机碳含量和储量增加 (5.4–14.5 %)。农用和后农生生态系统土壤的特点是基本养分(P-P2O5 高达 386 mg kg-1,K-K2O 高达 239.0 mg kg-1)和粘土(高达 20.9%)含量相对较高,与 Nadym 区的参考灰化唑相比,它们的微观结构程度也有所增加。土壤微生物组的分类组成在土壤的农业开发过程中也发生了很大变化。参考 Podzols 变形菌门、放线菌门和拟杆菌门占主导地位。一般来说,农用土壤和后农用土壤中的微生物特征转向变形菌门、酸菌门、浮霉菌门、亚硝化螺旋菌门、疣微菌门(用于废弃土地)和放线菌门、拟杆菌门、厚壁菌门、Euryarchaeota门(用于使用的土壤)。
