Laboratory and field tests have shown that accelerated compression of peat soils occurs in response to moderate heating and an effective overconsolidation is produced on subsequent cooling. This phenomenon has been termed thermal precompression. In this study, long-term laboratory and field tests were conducted to investigate secondary compression behavior of peat as a function of stress and te...

Metal adsorption and surface charge determinations were performed previously on well-characterised Sphagnum and Carex peat samples. The aim of this investigation was to determine metal adsorption from complex wastewaters onto these peat samples and compare it to the adsorption onto peat granules, clinoptilolite, glauconite and a flue dust from steel production. A sulphide mine leachate, a landf...

The paper studies the individual composition of n-alkanes, polycycloaromatic hydrocarbons, steroids, bi-, tri-, and pentacyclic terpenoids of two peat deposits of rich fen Kirek located in Western Siberia. Considering the individual n-alkanes concentrations, some indexes were calculated to estimate the humidity during peat formation. It was shown that the pH of peat medium primarily affects ste...

Triton X-114 (Triton X-114) surfactant separates into two isotropic phases at room temperature and can be successfully used in cloud point extraction for the analysis of polycyclic aromatic hydrocarbons (PAHs). We studied which type of container is the most suitable for PAHs extraction with this method and how the water affects PAH recovery. We used a generator and mini-centrifuge with a cloud ...

The purpose of the present study was to investigate the effects of feeding peat as a supplement in the period after weaning on the performance and health status of pigs. Also to assess the risk of the development of tuberculous lesions in the lymph nodes and parenchymatous organs, caused by conditionally pathogenic mycobacteria present in peat. Twenty Large White × Landrace pigs in equal number...

Data obtained by independent tests on each of 483 batches of Rhizobium inoculants for Glycine max, Medicago sativa, and Arachis hypogaea, manufactured commercially in South Africa, are reported and discussed. Whereas the average cell count per gram per batch was well in excess of 10, inoculants for G. max and M. sativa manufactured with peat treated with gamma irradiation at a dose of 50 kGr co...

Peat use in horticulture is associated with a large ecological footprint. the predominant growing media Europe. Modern cropping systems rely heavily on dynamic interactions of crop microorganisms and yet, search for sustainable peat-alternatives, microbiome has often been ignored. In mushroom cultivation, peat prime determinant productivity, form casing soil which supplies beneficial microbes. ...

Scientific knowledge of the wet zone - the lagg - that tends to form at the edge of ombrotrophic peatlands is surprisingly limited. In this study, we aim to improve the understanding of the ecohydrological functions of this transition by describing the form and abiotic controls of the laggs and margins of bog peatlands. Data collected in wells and piezometers along 10 transects (within 6 bogs),...

The present paper investigates the influence of stabilization with cement, peat ash, and silica sand on permeability coefficient (kv) of compacted clay, using a novel approach to stabilize the clay with peat ash as a supplementary material of cement in the compacted and stabilized soil. In order to assess the mentioned influence, test specimens of both untreated and stabilized soil have been te...
