Experimental warming reduced topsoil carbon content and increased soil bacterial diversity in a subtropical planted forest

Soil Biology and Biochemistry, 2019
The potential effects of global warming on the soil carbon (C) dynamics of subtropical forests are uncertain. To assess the effects of warming on soil C and tree roots, combined soil warming (infrared heaters, +1.5 °C soil temperature) and trenching ...

Preparation of topsoil alternatives for open-pit coal mines in the Hulunbuir grassland area, China

Applied Soil Ecology, 2020
To solve topsoil shortages caused by the thinner topsoil layer resulting from open-pit land reclamation in northwestern Chinese grassland areas, the overlying rock and soil layer of an open-pit coal mine in Inner Mongolia was used as a matrix, and ...

Regional Spatial Modeling of Topsoil Geochemistry

Biometrics, 2009
Summary Geographic information about the levels of toxics in environmental media is commonly used in regional environmental health studies when direct measurements of personal exposure is limited or unavailable. In this article, we propose a statistical framework for analyzing the spatial distribution of topsoil geochemical properties, including the ...

Evaluation of potential topsoil productivity

Environmental Geochemistry and Health, 1985
A biomass productivity model based on soil properties and climate is developed from literature and used to evaluate and compare potential effects of mining and reclamation on several soils in the continental United States. Soil productivity is assumed to vary as a product of root distribution function modified by five soil properties: available water ...

The quality of topsoil

Soil Use and Management, 1989
Abstract. The topsoil widely bought and sold for landscaping and similar schemes is intended to cover poor substrates and to provide improved growing conditions for plants. Two extensive surveys have shown that top soils at present being used are of very poor quality and rarely meet this requirement. Many of the
