Influence of Substitution of Peat with Iranian Zeolite(Clinoptilolite) In Peat Medium on Ficus Benjamina Growth
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...

متن کاملInfluence of peat formation conditions on the transformation of peat deposit organic matter
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...
متن کاملDrainage of Peat and Muck Lands Drainage of Peat and Much Lands
Peat and muck soils have unique biological, physical, and chemical properties, and on them the common drainage and management practices that are used on mineral soils are not suitable. Biologically the organic soils support hosts of micro-organisms, mostly bacteria, which are largely responsible for the formation and alteration of the peat. The action of the anaerobic micro-organisms builds up ...
متن کاملEffect of peat decomposition and mass loss on historic mercury records in peat bogs from patagonia.
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...
