Ghaly, A.E., Alkoaik, F. and Snow, A, 2007. Degradation of pirimiphos-methyl during thermophilic composting of greenhouse tomato plant residues. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 49: 6.1 6.11. The effectiveness of invessel thermophilic composting on the destruction of pirimiphos-methyl (12, 24, and 36 mg/kg dry matter) was evaluated. The bioreactor operated on a...

This review covers aspects of soil science and soil biology of Antarctica with special focus on King George Island, South Shetlands, the martitime Antarctic. New approaches in soil descriptions and soil taxonomy show a great variety of soil types, related to different parent material, mainly volcanic origin, as well as on influences by soil biological processes. The spread of higher rooting pla...

Humification of oxygen prior to administration by nasal cannula is an expensive practice which has been justified on the basis that it improves the comfort of patients receiving supplemental oxygen therapy. Routine humidification of low-flow oxygen (less than or equal to 4 L/min) delivered by nasal cannula has recently been challenged based on theoretic grounds and on the results of a clinical ...

This study presents results from field surveys performed over various seasons in a large, eutrophic, shallow lake (Lake Taihu, China) using an in situ chromophoric dissolved organic matter (CDOM) fluorescence sensor as a surrogate for other water quality parameters. These measurements identified highly significant empirical relationships between CDOM concentration measured using the in situ flu...

In this study, results about sludge stabilization in reed bed systems (RBSs) after the entire period of operation in two different systems situated in Denmark (Helsinge 42,000 population equivalent (p.e.) - 10 years) and in Italy (La Fontina, 30,000 p.e. - 6 years) were presented. In order to evaluate the process of sludge stabilization, parameters that highlighted the biochemical and chemico-s...

Flash pyrolysis-gas chromatography/mass spectrometry(Py-GC/MS) was used to study the structural transformations of humic fractions formed as a result of composting processes of diverse organic materials (solid wastes of wineries, solid olive-mill wastes, domestic wastes, ovine manures plus straw, and mixtures of animal manures). Sodium hydroxide-extracted total humic-like extracts (THE; humic p...

The objective of this work was to investigate the potential of three different kinds of Iranian peat and swamp soils as sources of organic matter (OM) in the Golestan Province, Northern Iran. Comparison of the peats was done in terms of the degree of humification on the von Post scale. Moreover, the X-ray fluorescence, X-Ray Diffractometry, and Fourier transform infra-red (FT-IR) techniques wer...

Abstract In Malaysia, peat soils have been successfully planted with various crops such as pineapple, oil palm, and sago. However, the development of to plantations may raise problems environment alter their physical morphological characteristics. Hence, this study was conducted differentiate microstructure between natural pineapple cultivated peat. The soil samples were taken at 0-50 cm, 50-10...

In this study, we have provided new and important findings with regards to the spatial distribution of DOM concentration, bioavailability, optical properties during early summer hydrologic conditions within Bakcharsky bog complex in southern taiga subzone Western Siberia. Data on biodegradable fractions surface soil waters were obtained basis laboratory experiments analytical work. Surface land...

Humate substances (HSs) are raw materials very easy to obtain and naturally occurring organic molecules found in soil due the humification of dead components. Traditionally used as conventional medicine China India fertilizer agriculture. Humic acids widely utilized feed additives could enhance ruminant performance. The effect humic acid on intake depends level supplementation, a source, experi...
