Russian knapweed (Acroptilon repens [L.] DC.), an exotic perennial forb, has invaded many native ecosystems in western North America. Russian knapweed’s success is attributed to allelopathy, extensive tap rooting, zinc accumulation in soils, and a

Mandated uniform topsoil replacement may hinder or prevent compliance with reclamation bond release standards such as canopy cover, aboveground production, shrub density, and diversity. This investigation was conducted at a coal mine in northeastern

Uniform topsoil replacement depths on coal mine reclaimed areas have been mandated by USA federal and state regulations; however, soils of the premine landscape are not naturally uniform in depth and vary in physical, chemical, and biological charact

Management of soils on areas subjected to planned disturbance, such as surface mine sites, is crucial to post-disturbance restoration. We conducted a study to determine which of the following two topsoil management strategies resulted in less of a ne

In the western USA, wildland soil survey areas are often large, and the resources of money, personnel, and time required for conventional soil survey techniques are in short supply. We evaluated an alternative methodology for producing soil maps thro

Spatial variability of soils is a landscape attribute which soil scientists must identify and understand if they are to construct useful soils maps. This paper describes the spatial variability of soils in a forested watershed in the Medicine Bow Mou

Statistical and geostatistical analyses were conducted to estimate both correlation and spatial distributions of trace elements in soils and plants within a corn field. Statistical analysis of AB-DTPA-extractable trace elements in soils and the total

A variety of extractants has been used to assess the availability of molybdenum (Mo) in soils. Most of the extractants have been studied from a deficiency aspect rather than for soils with Mo toxicity, and none of them have been used to extract avail
