Approximately 15 percent of Sweden’s land area is covered by peat ( 30 cm deep). In drained peatlands, decomposition of the peat produces greenhouse gases such as CO2 and N2O. Electric conductivity, measured with the instrument EM38, can be used to assess spatial variation in soil properties. To easier decide the quantity of the CO2-emissions from a peatland the possible relation between electr...

background: lemon verbena (lippia citriodora h.b.k.) is an aromatic and medicinal plant of family verbenaceae, which cultivated in north region of iran. objective: evaluation of phytochemical characters in lippia citriodora h.b.k. plantlets affected by propagation methods (micro-propagation and stem cutting) cultivated in different soil type (peat moss and mixture soil). methods: this study was...

this experiment was designed to characterize the effects of size and concentration of an iranian clinoptilolite zeolite on the growth officus benjamina (starlight) in peat base media. ficus benjamina was stock rooted and grown in a peat consisting perlite (2: 1 v/v) (p: pe), zeolite (10, 20, 30 and 40 v/v %, two sizes 0.5-3 mm and 3-8 mm) instead of peat in p: pe (2: 1 v/v) media. ficus benjami...

J. Inst. Brew. 112(4), 333–339, 2006 It is not known if peats derived from different areas of Scotland have distinctive chemical constituents that could impact on malt whisky in discernible organoleptic ways. Fourier transforminfrared (FT-IR) spectroscopy was used as a high throughput screening method to investigate discrimination of a large number of peat samples from six different geographica...

One source of energy, the importance of which has been realized with the advance of increasing fuel prices, is peat, a renewing resource of nature typical for some areas in northern Europe. Because of the comparatively difficult processing properties of peat and the quite short history of efficient development on this area the technology of peat burning plants now needs a systematic programme o...

The majority of the catchment (area 0.95 km2) is corered by a thin deposit of blanket peat. Peats, over 5 m deep in places, occur in small valley depressions. Two transects across the depressions were selected for a radiocarbon and palaeoecological study into peatland initiation and development (Jones, 1987). As in the Loch Dungeon study, analysis of pollen from peat profiles enables a picture ...

The decline of atmospheric CO2 over the last 65 million years (Ma) resulted in the 'CO2-starvation' of terrestrial ecosystems and led to the widespread distribution of C4 plants, which are less sensitive to CO2 levels than are C3 plants. Global expansion of C4 biomass is recorded in the diets of mammals from Asia, Africa, North America, and South America during the interval from about 8 to 5 Ma...

Many studies have suggested that South American camelids (SAC) have greater digestive efficiency than pecoran ruminants, but others have found no difference. In an effort to provide new data on this issue, we investigated the ability of SAC (alpacas and llamas), goats, horses, and rabbits to digest C3 (Bromus inermis) and C4 (Cynodon dactylon) grass hay with nearly equal nitrogen and cell wall ...
