Some of arid regions problems of Iran are saline and sodic soils. In improvement and reclamation of Iranian arid rangelands, some foreign species of Atriplex had been imported and adapted for many years ago. The most adapted species was Atriplex canescens. At the present research, some environmental factors, vegetative characteristics (Na, Ca, Mg and K), soil properties (moisture, EC, pH, solut...

The aim of this paper is the analysis and preservation of lime kilns, focusing on the structure, construction, and functionality of vertical shaft lime kilns of the Cap Corse in Corsica. Plans and sections of two lime kilns are presented in detail, providing an overall picture of this specific industrial heritage. The potential damage areas are identified performing structural analysis of a lim...

Measurement of soil CO2 efflux using a non-flow-through steady-state (NFT-SS) chamber with alkali absorption of CO2 by soda lime was tested and compared with a flow-through non-steady-state (FT-NSS) IRGAmethod to assess suitability of using soda lime for field monitoring over large spatial scales and integrated over a day. Potential errors and artifacts associated with the soda lime chamber met...

A pilot heat exchanger – cooling tower prototype was constructed and used for the evaluation of scale inhibitors in the inhibition of calcium carbonate (CaCO3) precipitation and deposition. The chemical additives that were used as inhibitors were 2phosphonobutane-1,2,4-tricarboxylic acid (PBTC, Dequest 7000), bis(hexamethylene triaminepenta (methylenephosphonic acid)) (BHPMP, Dequest 2090) and ...

Stromatolites are laminated, lithified (CaCO3) sedimentary deposits formed by precipitation and/or sediment accretion by cyanobacterial-bacterial mat communities. Stromatolites have been associated with these communities as far back as the Precambrian era some 2+ billion years ago. The means by which microbial communities mediate the precipitation processes have remained unclear, and are the su...

abstract in order to study the chemical behavior of nickel and cadmium in the presence of organic matter, an experiment with two different soils (4 and 30 percent caco3), two different texture (8 and 40 percent clay), two levels of nickel (0 and 100 mg.kg-1), two levels of cadmium (0 and 25 mg.kg-1) and organic matter in the form of sewage sludge in two levels (0 and 100 t. ha-1), at three time...

abstract a study was conducted to evaluate the effect of incubation time, sewage sludge and clay content on the distribution of nickel and cadmium in different fractions of selected calcareous soils. to meet this purpose, an experiment with two different soils (4 and 30 percent caco3), two different textures (8 and 40 percent clay), two levels of nickel (0 and 100 mg.kg-1), two levels of cadmiu...

A microcosm-based approach was used to study impacts of plant and chemical factors on the bacterial community structure of an upland acidic grassland soil. Seven perennial plant species typical of both natural, unimproved (Nardus stricta, Agrostis capillaris, Festuca ovina and F. rubra) and fertilized, improved (Holcus lanatus, Lolium perenne and Trifolium repens) grasslands were either left un...

The yield responses of sugarcane to lime and gypsum at two sites in the KwaZulu-Natal Midlands of South Africa are presented and discussed. At Dalton, on a Magwa form soil with an initial aluminium saturation index (ASI) of >80%, over a plant and four ratoon crops variety N12 gave no significant response to dolomitic lime. By contrast, variety N16 gave consistent yield responses to lime at rate...
