The effects of repeated atrazine application (40 mg a.i.kg(-1)) on its degradation, microbial communities and enzyme activities were studied in a peat based biomixture composed by straw, soil and peat in the volumetric proportions of 2:1:1 that can be used in on-farm biopurification system. Atrazine removal efficiency was high (96%, 78% and 96%) after each atrazine application and did not show ...

The substrates composition can take place from different raw materials, being an influencer of the water and nutrient retention capacity, important dynamic in management cultivation containers due to possibility leaching. It was aimed quantify Potassium adsorption with proportions vermiculite peat, addition determining isotherms which would best fit observed data, for contact periods one seven ...

During the 1997/98 El Niño-induced drought peatland fires in Indonesia may have released 13-40% of the mean annual global carbon emissions from fossil fuels. One major unknown in current peatland emission estimations is how much peat is combusted by fire. Using a light detection and ranging data set acquired in Central Kalimantan, Borneo, in 2007, one year after the severe peatland fires of 200...

Background: The composition of the planting beds and its microorganisms has a very important role on the establishment, growth and phytochemical performance of medicinal plants. Objective: The aim of this study was to determine the effect of different planting beds and inoculation of mycorrhizal fungus on the changes of stevioside, rebaudioside, and morpho-physiological traits of stevia. Meth...

During 1997 and 1998 intensive land irrigation and clearance activities in Indonesia, combined with a greatly extended ENSO-related dry season, created conditions for several months of forest fires. Fires were particularly intense in the lowland peatlands of Kalimantan and Sumatra where both forest and peat fires occurred. A 24,910 km (2.491 MHa) study area in Central Kalimantan has been used t...

The first overview on the Auchenorrhyncha fauna of peat bogs of the Austrian Bohemian Forest is presented. Seven oligotrophic peat bog sites were studied in 2011 by suction sampler ("G-Vac") and 93 Auchenorrhyncha species (with 7465 adult specimens) were recorded. Eleven species (about 18 % of the individuals) are tyrphobiontic or tyrphophilous. The relative species abundance plot is not very s...

Batch sorption experiments were performed for the removal of chromium(III) ions from aqueous solutions using Romanian Sphagnum moss peat (untreated and treated with NaCl solution) as sorbent. In order to establish the best conditions for the sorption of chromium(III), the influence of initial pH, contact time, peat dose and metal ion concentration was investigated. The Freundlich, Langmuir and ...
