to try and ascertain the relative importance of different soil properties for calibration. This approach has good Many empirical formulas relating TDR-measured permittivity (Ka) utility for finding simple and practical equations that can to volumetric water content ( ) have been presented owing to the lack of a robust and accurate physically derived model describing this be used to estimate .

Soils can serve as sorbents for phosphorus (P), negating the need for artificial sorbents. The purpose of this study was to compare soils with different properties for their effect on nutrient levels in effluent. Four soils were mixed with sand and packed into columns 0.5 m long, with or without compost on the surface. Infiltration and effluent concentrations were measured before and after grow...

AA and its esters are unlikely to persist in the environment. Acrylates have medium to high mobility for adsorption and desorption to soils. They are not expected to bind to soil or sediment. If released to air, they will undergo photo-degradation within days. AA and all of the esters are readily biodegradable except t-BA, which is inherently biodegradable. In contact with water, abiotic hydrol...

The effluent generated from a thermal power plant waste is a mixture of several chemicals and to identify the effect of these chemicals on soil, a case study on naturally contaminated sites at Al-Musayyib region, Hilla city in Iraq has been carried out. Soil and water samples were collected from the sites and analyzed to identify the pollutants and their effect on soil characteristics. Laborato...

Genetic analysis of the location of a mini-Tn5 promoted insertion of the LB400 bph operon in the rhizosphere coloniser Pseudomonas fluorescens F113rifPCB, allowed the development of a specific PCR detection system based on the unique DNA sequence at this insertion site. Real time PCR using both SYBR green chemistry and Fluorescence Resonance Energy Transfer probes allowed the precise identifica...

The remotely-sensed soil depth in the visible and near-infrared (near-IR) spectral region is investigated by using a numerical radiative transfer model of the coupled atmosphere and soil media. The sensible depth is determined by examining the downward hemispheric transmittance pro® le, hemispherical re ̄ ectance, and bidirectional re ̄ ectance with diVerent solar zenith angles at diVerent wavele...
