Edaphic Controls Override Climatic and Management Effects on Soil Organic Carbon in Southern African Agroecosystems

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Understanding the relative importance of climatic, edaphic, and management controls on soil organic carbon (SOC) is essential for improving SOC prediction and land management in data‐scarce agroecosystems. Aim This study quantified SOC drivers across Southern African agroecosystems using 655 observations covering climatic variables,

Where geology meets pedology: Late Quaternary tephras, loess, and paleosols in the Mamaku Plateau and Lake Rerewhakaaitu areas [PDF]

, 2012
On this trip we focus on tephrostratigraphy and soil stratigraphy together with aspects of palaeoenvironmental reconstruction over long and short time-spans.

Reconstructing the Last 71 ka Paleoclimate in Northeast China by Integrating Typical Loess Sections

Quaternary
Long-term continuous deposits and well-preserved thick loess sections are natural archives for the reconstruction of global climate change. However, the loess sections are often discontinuous owing to soil erosions and accumulations.

Soil Fertility Changes With Climate and Island Age in Galápagos: New Baseline Data for Sustainable Agricultural Management

Frontiers in Environmental Science, 2021
While the extended absence of human influence has led to matchless natural conditions on the Galápagos archipelago, agricultural activities on the inhabited islands are increasingly affecting soil health and functioning.

The German Soil Systematics and the Rationale Behind Its Revision

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

Infrared Spectroscopic Predictions of Soil Properties for Agricultural Monitoring: Statistical and Soil Spectroscopic Considerations

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Pseudo‐independent validation (PIV) using regional datasets is common in visible‐to‐near‐infrared (vis–NIR) and mid‐infrared (MIR) spectroscopy studies and produces accurate predictions but is relevant only to regional‐scale monitoring of known sites.

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Development in Soil Chronosequence Research from 1994 to 2024: A Bibliometric Analysis Using CiteSpace

Agriculture
Soil chronosequences are crucial for understanding pedogenesis and ecosystem dynamics, yet a systematic bibliometric analysis of this field remains absent.

Stable isotope analysis of freshwater gastropod carbonates from Swanscombe: Insights into climate stability and seasonality during MIS 11c

Journal of Quaternary Science, EarlyView.
ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

Rates of soil-forming processes in three main models of pedogenesis 283 Rates of soil-forming processes in three main models of pedogenesis [PDF]

, 2020
Rates of soil-forming processes were evaluated for the three major models of pedogenesis: (1) normal "top-down" soil development (pedogenesis transforms the parent material under a geomorphically stable surface), (2) soil development ...
