This article contains a statistically analyzed dataset of the heavy metals including Cr, Co, Ni, Cu, Zn and Pb contents of near-surface (~30 cm depth) soils in a Cu-Ni prospecting field at Airstrip North, Central Botswana. The soils developed on paragneisses and amphibolites parent materials in a semi-arid environment with hardveld vegetation, "The geology of the Topisi area" (Key et al., 1994)...

Soils of the Solonetzic Order account for about 7% of the agricultural land in Western Canada. They are most common in semi-arid regions (the Brown and Dark Brown soil zones) but occur as well in the Aspen Parkland and even under forest. They occur on parent materials containing sodium salts, or in lowland areas influenced by ground water discharge. Solonetzic soils are often referred to as cla...

A prototype map of radon potentials in Alachua County, Florida is being developed to demonstrate the feasibility of defining geographic criteria for implementing radon-protective building construction standards. Because of regulatory needs and sensitivities, the map is being developed independent of institutional boundaries or of particular present radon limits. I t defines the radon source pot...

Organic matter is essential in improving the physical, chemical and biological properties of soils. Thus, organic widely considered a crucial indicator environmental quality biodiversity. In this study, effect gyttja addition as soil conditioner on some physical soils formed volcanic serpentine parent materials was investigated. The layout incubation study randomized plots with 3 replications l...

Abstract Purpose Information about particle size distribution (PSD) and soil texture is essential for understanding drainage, porosity, nutrient availability, trafficability. The sieve-pipette/gravimetric method traditionally used analysis labour-intensive resource-intensive. X-ray fluorescence (XRF) spectrometry may provide a rapid alternative. study’s aim was to examine the use of XRF determi...
