It has been observed that there are sustained electrical potential difference and current between a tree trunk and its surrounding soil, which have bright application prospects for powering wireless sensor networks in forests. But the mechanism of the bioelectricity has remained controversial. In order to provide more comprehensive data for further researches and to analyze the relationship bet...

This study presents the experimental remediation studies of diesel contaminated soil with Sodium Deducible Sulfate (SDS) as surfactants using column tests. Sandy selected soil had the grain size distribution of # 40 meshes to the # 200 mesh range. The soil columns were contaminated with adequate diesel amount to achieve the concentration of 10000 and 20000 ppm in soil. 0.1, 0.2, 0.3, 0.4 percen...

The rates of extraetíon of Na, K, Mg, Ca, and Al with 1 M NH. NO. from the mineraIand organic-rieh layers of sorne Park Grass (Rothamsted) soils were measured at the pH of the soil. Below pH 3.7 exehangeable Al, deríved from the kineties curve, inereases with decreasing soil pH and is less in the organic-rich Iayer. The sum of the basic exchangeable eations, I;(Na + K + Mg + Ca), increases with...

Silicon (Si) is important in mitigating abiotic and biotic plant stresses, yet many agricultural soils, such as those of the rainfed production areas of the South African sugar industry, are deficient in plant-available Si, making Si supplementation necessary. However, Si uptake by sugarcane (Saccharum spp. hybrids) is limited even where silicate amendments improve soil Si status. Rhizosphere p...

Soil incubations are a common practice typically employed in assessing the effect of some treatment on the availability and solubility of phosphorus (P). However, standard sample preparation (drying and sieving) can alter soil chemical and physical properties, resulting in possible changes in P behavior upon soil incubation. Sixty surface soil samples were collected, air dried, and sieved befor...

Effects of copper (Cu) and aluminum (Al) on the adsorption of sulfathiazole (STZ) and tylosin (T) to peat and soil were investigated using a batch equilibration method. Results show that Cu suppressed STZ adsorption onto peat and soil at pH < 5.0 because of the electrostatic competition, while increased STZ adsorption at pH > 5.0 due to the formation of STZ-Cu complexes and/or Cu bridge. In con...

Post mortem changes are important in estimating post mortem interval (PMI). This project's aim was to study the effect of burial and type of clothing on rate of decomposition, which can contribute to estimating PMI for victims. 12 rabbits (Oryctolagus cuniculus) carcasses were separated into 3 groups: no clothing, light clothing and heavy clothing. Control subjects were placed on the ground sur...

Schnürer, Y., 2006. Influence of soil properties and organic pesticides on soil microbial metabolism. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7267-9. In many areas of the world undesirable dispersal of organic pesticides into untargeted environments has occurred, and is continuing, raising serious concerns about their potential impact on the environment and human health. The main age...
