Evaluation and Spatial Variability of Cryogenic Soil Properties (Yamal-Nenets Autonomous District, Russia)

Agricultural development in northern polar areas has potential as a result of global warming. Such expansion requires modern soil surveys and large-scale maps. In this study, the abandoned arable experimental field founded by I.G. Eichfeld one century ago Salekhard city (Russian Arctic), located circle, was investigated. Our aims were to assess nutritional properties their spatial variability. For assessment mapping, ordinary kriging (OK) inverse distance-weighted (IDW) methods employed. We found that due long-term agriculture use, cover represented unique Plaggic Podzol (Turbic) is not typical region. The characterized relatively low organic carbon (SOC) content, high acidity content plant-available forms phosphorus humus-accumulative horizon. results showed some (pH H2O, pH CaCl2) heterogeneity clear dependence. However, (ammonium nitrate nitrogen, basal respiration) pure-nugget effect, presumably experimentation with fertilizer over long period time.
