Peat moss (PM) is the most widely used growing substrate for the pot culture. Due to diminishing availability and increasing price of PM, researchers are looking for viable alternatives for peat as a growth media component for potted plants. A pot study was conducted with a view to investigate the possibility of using spent mushroom waste (SMW) for Kai-lan (Brassica oleracea var. Alboglabra) pr...

Ombrotrophic peat bogs have been widely used to evaluate long-term records of atmospheric mercury (Hg) deposition. One of the major aims of these investigations is the estimation of the increase in atmospheric Hg fluxes during the industrial age compared to preindustrial fluxes. Comparability of Hg accumulation rates calculated from density, peat accumulation rates, and Hg concentrations requir...

[1] The surface pattern of vegetation influences the composition and humification of peat laid down during the development of a bog, producing a subsurface hydrological structure that is expected to affect both the rate and pattern of water flow. Subsurface peat structures are routinely derived from the inspection of peat cores. However, logistical limits on the number of cores that can be coll...

ruffling is a practice through which the mycelia containing casing soil will be thoroughly mixed. to evaluate the effects of ruffling of different casing soils in button mushroom production, an experiment was conducted comprised of three levels of ruffling; no ruffling, deep ruffling vs. superficial scratch and eight different types of casing soils, namely: holland peat (c1), north peat (c2), s...

A properly conducted vermicomposting process is an environmentally friendly technology used to transform selected organic waste into vermicompost. This fertilizer increasingly in agriculture and horticulture as alternative mineral fertilizers. Research has investigated the use of vermicompost made from mass sugar beet pulp a soil additive cultivation peas (Pisum sativum L.). Experimentally, fiv...

A pseudo-second order rate equation describing the kinetics of sorption of divalent metal ions on to sphagnum moss peat at various initial metal ion concentrations and peat doses has been developed. The sorption kinetics were followed based on the concentrations of metal sorbed at various time intervals. Results show that chemical sorption processes might be rate-limiting for the sorption of di...

Peat is a common substrate used for the cultivation of potted plants. However, use peat in horticulture has recently been questioned from an environmental standpoint, since it non-renewable resource and plays major role atmospheric CO2 sequestration. The aim this work was to assess potentialities substrates obtained vermicompost, compost anaerobic digestion processes partially substitute sage (...

Stability assessment of existing dikes build on soft soil generates questions on the available stability calculation techniques and material models. Especially peat behaviour is not easily captured by standard design methods. This has led to disapproval, based on calculations, of dikes that have been in operation for several hundreds of years. To establish the weak points in the stability asses...
