This paper presents a new approach to predict soil properties and quantify uncertainty in the derived soil property maps over large areas using sparse and ad-hoc samples. According to the soil-landscape model, each soil sample contains corresponding relationships between soil and environment conditions. Under the assumption that the more similar the environment conditions between two locations ...

To isolate potential insect biocontrol agents, entomogenous nematodes were surveyed in Tennessee plant nurseries in 1991. Soil samples from 113 nursery sites were baited with greater wax moth (Galleria mellonella) larvae, house cricket (Acheta domesticus) adults, lesser mealworm (Alphitobius diaperings) adults, and house fly (Musca domestica) larvae. Heterorhabditis bacteriophora and Steinernem...

In the present work, a method for the analysis of the residues of chlorpyrifos and its toxic metabolite 3,5,6-trichloro-2-pyridinol (TCP) in agricultural soil and apples was developed. The residues of chlorpyrifos and TCP were extracted from agricultural soil and apple samples by shaking followed clean-up by liquid-liquid extraction (LLE) and solid-phase extraction (SPE) coupled with detection ...

Angelovičová L., Fazekašová D. (2014): Contamination of the soil and water environment by heavy metals in the former mining area of Rudňany (Slovakia). Soil & Water Res., 9: 18–24. Contamination of soil and water environment by heavy metals in a former mining area and their effect on the soil characteristics were determined. Soil samples were collected in the village of Rudňany which is, accord...

We investigated the toxicity of soil samples derived from a former municipal landfill site in the South of the Netherlands, where a bioremediation project is running aiming at reusing the site for recreation. Both an organic soil extract and the original soil sample was investigated using the ISO standardized Folsomia soil ecotoxicological testing and gene expression analysis. The 28 day surviv...

The present study evaluates the genotoxic potential of different soil samples collected from rice fields employing Allium cepa root chromosomal aberration assay using in situ and root dip modes of treatment. The study also involves assessment of oxidative stress by analyzing responses of certain antioxidative enzymes viz. catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR), g...

Denitrification may represent an important mechanism in the fate of N applied to turf. Denitrification losses were directly measured from fertilized 'Baron' Kentucky bluegrass (Poa pratensis L.) sod samples sealed in acrylic chambers using the acetylene inhibition technique. Losses were correlated with soil texture, percent soil sat· uration (SAT), and temperature. Losses from turf on a Hadley ...
