Overcoming topsoil deficits in restoration of semiarid lands: Designing hydrologically favourable soil covers for seedling emergence

open access: yesEcological Engineering, 2017
Topsoil replacement is a standard procedure in restoration of mined landscapes as it provides a source of propagules via the soil seed bank, as well as provides favourable physical, chemical and microbiological properties for plant establishment.

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

Arsenic mobility and stabilization in topsoils

Water Research, 2009
Agricultural topsoil can be polluted with arsenic due to irrigation with contaminated water from geothermal sources. This work evaluates the mobility of arsenic in topsoils and stabilization of arsenic with zero valent iron (ZVI), in short term experiments. The objective of this study was the development of a simplified empirical model that can predict

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 ...
