Analysis of spatial heterogeneity of soil physicochemical properties in northern Malawi Geoderma Reg. (IF 4.1) Pub Date : 2023-10-28 Jabulani Nyengere, Yuki Okamoto, Shinya Funakawa, Hitoshi Shinjo
Topography and fertility management practices are critical when examining distribution of spatial heterogeneity of soil properties. The study was carried out on a 52-ha land with undulating topography of a village in Northern Malawi to analyze spatial soil heterogeneity with attention to topography and soil fertility management practices in 2021. The spatial heterogeneity of 12 soil chemical properties

Soil distribution and soil properties in the subalpine region of Kazbegi, Greater Caucasus, Georgia: Physicochemical properties, distribution and genesis Geoderma Reg. (IF 4.1) Pub Date : 2023-10-31 Thomas Hanauer, Tim Grzelachowski, Boris Vashev, Leonard Böhm, Benjamin Justus Heyde, Besik Kalandadze, Tengiz Urushadze, Peter Felix-Henningsen
Due to their characteristic properties, mountain soils require adequate management if used for cropping or grazing, even if climatic conditions are favorable. This study provides a summary of a three-year field campaign that evaluated mountain soils in in northern Georgia for sustainable agricultural use. Soils in the Kazbegi study area, located on the northern slope of the Great Caucasian Ridge, were

Heavy minerals as indicators of source material in soils on carbonates Geoderma Reg. (IF 4.1) Pub Date : 2023-10-31 Barbara Čeplak, Miloš Miler, Nina Zupančič, Simona Jarc
The origin of the soils formed on carbonate rocks remains uncertain, as they are probably of polygenetic origin. Of particular interest are the elevated contents of some trace elements detected in these soils, as they can hardly be attributed to insoluble residues of carbonate rock. The aim of this study was to uncover the relationship between heavy minerals in bedrock and soil and to identify other

The effect of land-use conversion from agriculture to perennial biomass crops and nitrogen fertilizer on soil organic carbon stock in southern Ontario, Canada Geoderma Reg. (IF 4.1) Pub Date : 2023-10-24 Sowthini Vijayakumar, Holly Patricia Ivany, Amir Behzad Bazrgar, Bill Deen, Mahendra Thimmanagari, Kimberley Schneider, John Lauzon, Paul Voroney, Naresh Thevathasan
Switchgrass [Panicum virgatum, (SG)] and miscanthus [Miscanthus spp., (Mis)] are perennial biomass crops (PBCs) commonly grown in Ontario, Canada. By the integration of PBCs on marginal/degraded agricultural (Ag) fields, a positive gain in soil organic carbon (SOC) sequestration has been reported in the scientific literature. Therefore, using PBCs to enhance SOC sequestration can potentially contribute

Geospatial modelling of soil phosphorus fractions and sorption indicators from heterogeneous landscapes in Ireland Geoderma Reg. (IF 4.1) Pub Date : 2023-10-24 Rebecca L. Hall, Felipe Bachion de Santana, Margaret A. Browne, Vincent Gallagher, Eric C. Grunsky, Victoria Lowe, Karen Daly
Soil mapping of phosphorus (P) pools at regional scale can be used to inform policy and land management strategies in agri-environmental systems. However, linking an element that is predominantly managed by fertiliser and organic inputs to regional scale geochemistry can be problematic. This study used a geological survey of the northern half of Ireland at ≤4 km2 resolution to map total P (ICP aqua

Estimating natural soil drainage classes in the Wisconsin till plain of the Midwestern U.S.A. based on lidar derived terrain indices: Evaluating prediction accuracy of multinomial logistic regression and machine learning algorithms Geoderma Reg. (IF 4.1) Pub Date : 2023-10-18 Shams R. Rahmani, Zamir Libohova, Jason P. Ackerson, Darrell G. Schulze
Accurate spatial prediction of natural soil drainage condition is not only important for agriculture and hydrological modeling but also for installing subsurface drainage and onsite waste disposal systems. For this research, 154 sites were selected based on a stratified random sampling method. For each site, drainage class was identified based on visual examination of soil cores. A digital elevation
