Earthworms modify plant biomass and nitrogen capture under conditions of soil nutrient heterogeneity and elevated atmospheric CO<inf>2</inf> concentrations
(Soil Biology and Biochemistry, 2014-01-01)Earthworms modify the way roots respond to soil nutrient patchiness. However, few studies have evaluated the joint effects of earthworms and soil heterogeneity on plant community biomass and species dominance, and none of ... -
Estimates and determinants of stocks of deep soil carbon in Gabon, Central Africa
(Geoderma, 2019-05-01)© 2019 Despite the importance of tropical forest carbon to the global carbon cycle, research on carbon stocks is incomplete in major areas of the tropical world. Nowhere in the tropics is this more the case than in Africa, ... -
Game Changer in Soil Science. The Anthropocene in soil science and pedology.
(Journal of Plant Nutrition and Soil Science, 2020-02-01)© 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim The venerable science of pedology, initiated in the 19th century as the study of the natural factors of soil formation, is adapting to the demands of the Anthropocene, ... -
Hydrologic Functioning of Low-Relief, Deep Soil Watersheds and Hydrologic Legacies of Intensive Agriculture in the Calhoun Critical Zone Observatory, South Carolina, USA
(2020)Watersheds are complex, three dimensional structures that partition water between the components of the water balance and multiple storage pools within the watershed. This central function, however, remains poorly understood ... -
Modifications of 2:1 clay minerals in a kaolinite-dominated Ultisol under changing land-use regimes
(Clays and Clay Minerals, 2018-02-01)© 2018, Clay Minerals Society. All rights reserved. Chemical denudation and chemical weathering rates vary under climatic, bedrock, biotic, and topographic conditions. Constraints for landscape evolution models must consider ... -
Quantification of Mixed-Layer Clays in Multiple Saturation States Using NEWMOD2: Implications for the Potassium Uplift Hypothesis in the SE United States
(Clays and Clay Minerals, 2020-02-01)© 2020, The Clay Minerals Society. Quantification of mineral assemblages in near-surface Earth materials is a challenge because of the often abundant and highly variable crystalline and chemical nature of discrete clay minerals. ... -
Redoximorphic Bt horizons of the Calhoun CZO soils exhibit depth-dependent iron-oxide crystallinity
(Journal of Soils and Sediments, 2019-02-12)© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Purpose: Iron (Fe) oxyhydroxides and their degree of ordering or crystallinity strongly impact the role that Fe plays in ecosystem function. Lower crystallinity ... -
Scientific concepts for an integrated analysis of desertification
(Land Degradation and Development, 2011-03-01)The Global Drylands Observing System proposed in this issue should reduce the huge uncertainty about the extent of desertification and the rate at which it is changing, and provide valuable information to scientists, planners ... -
Soil production and the soil geomorphology legacy of Grove Karl Gilbert
(Soil Science Society of America Journal, 2020-01-01)© 2019 The Authors. Soil Science Society of America published by Wiley Periodicals, Inc. on behalf of Soil Science Society of America Geomorphologists are quantifying the rates of an important component of bedrock's weathering ... -
The changing model of soil revisited
(Soil Science Society of America Journal, 2012-06-14)In 1961, the late Marlin G. Cline wrote a remarkable essay entitled, "The Changing Model of Soil" for the 25th Anniversary Issue of the Soil Science Society of America Proceedings. Cline was most impressed with how geomorphology ... -
Towards a global drylands observing system: Observational requirements and institutional solutions
(Land Degradation & Development, 2011)Quantitative data on dryland changes and their effects on the people living there are required to support policymaking and environmental management at all scales. Data are regularly acquired by international, national or ...
