Land Use Change Effect on Soil Carbon Stock and Selected Soil Properties in Gobu Sayyo District, Western Ethiopia. [PDF]

ScientificWorldJournal
Land use change is one of the major factors affecting soil degradation. Growing population pressure has increased land use change with more negative effects on soil carbon storage and overall soil properties. The objective of this study was to assess the effect of land use changes on soil organic carbon (SOC) stock and selected soil physicochemical ...

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia. [PDF]

Ecol Evol
Ectomycorrhizal fungi play essential roles in nitrogen cycling and plant nutrient uptake at high latitudes. However, they have disproportionately been studied in boreal forests dominated by evergreen conifers. We characterized ectomycorrhizal associations and the nitrogen economy of co‐occurring deciduous and evergreen angiosperms from the genus ...

Development of a lateral topographic weathering gradient in temperate forested podzols

Geoderma, 2023
Mineral weathering is an important soil-forming process driven by the interplay of water, organisms, solution chemistry, and mineralogy. The influence of hillslope-scale patterns of water flux on mineral weathering in soils is still not well understood ...

Soil toposequence under man-planted vegetation in the Krkonoše Mts., Czech Republic

Soil and Water Research, 2012
Mountainous areas represent regions with specific soil cover pattern that is naturally given by an altitudinal gradient. The objective of our study was to describe the soil cover development on the altitudinal gradient under changed environment given by ...

Soil Phosphorus Dynamics Across a Holocene Chronosequence of Aeolian Sand Dunes in a Hypermaritime Environment on Calvert Island, BC, Canada

Frontiers in Forests and Global Change, 2020
Phosphorus (P) is an essential nutrient for plant growth, but soil P concentrations decline with increasing soil age. Phosphorus often limits tree growth within the hypermaritime Coastal Western Hemlock zone in British Columbia, Canada, particularly ...

Profilowe zróżnicowanie form żelaza i glinu w glebach pod świerczyn górnoreglową Plagiothecio-Piccetum tatricum w Gorcach jako wskaźnik aktualnych procesów glebotwórczych / Distribution of Iron and Aluminum Forms as an Indicator of Present-Day Soil-Forming Processes in Soil Profiles under Wooded Spruce Plagiothecio-Piccetum Tatricum in the Gorce Mts. (Southern Poland)

Soil Science Annual, 2015
The aim of the study was to determine soil-forming processes in soils formed from the Magura sandstones (Carpathian flysch) under wooded spruce Plagiothecio-Piccetum tatricum in the Gorce Mts., southern Poland. The research focused on distribution of non-

Magnetic susceptibility of permafrost soils of the forest catena in Central Yakutia [PDF]

Сибирский лесной журнал, 2021
The magnetic susceptibility (MS) of three types of permafrost forest soils (pale-yellow, pale-brown, and podzolic) formed on permafrost soil-forming rocks in the cryoarid climate of Central Yakutia for the first time was studied.
