in this study, micromorphological properties of some samples collected from pedons polluted with petroleum refinery wastes and some adjacent unpolluted pedons were studied. after description of the studied pedons, disturbed and undisturbed samples were collected for physicochemical and micromorphological analyses. the results showed that the physicochemical properties (i.e. structure, bulk dens...

The aim of our experiment was to determine the effect of heating oil application on the count of microorganisms and some physico-chemical properties of limed and lime-free soil and soil sown with yellow lupine of the Markiz variety and unsown soil. The results obtained indicate that heating oil deteriorated the physico-chemical properties of the experimental soil (acidification, decrease in the...

rainfed wheat is the main source of staple food for people in the developing countries. various factors contribute to and affect the production of this crop. the aim followed in the present study was to develop a model to estimate rainfed wheat grain yield as based on physico-chemical properties of the soil. therefore, wheat grain yield and soil physico-chemical properties were separately deter...

The effect of pig iron slag particles on soil physico-chemical, biological and certain soil enzyme properties was studied. Contamination of iron slag particles altered physico-chemical, biological and enzyme properties of soil. While soil pH increased slightly, electrical conductivity, carbon, potassium and phosphorus contents increased significantly in polluted soil. Contamination of soil with...

(Received: November 27, 2010; Accepted: February 9, 2011) Abstract: The effect of pig iron slag particles on soil physico-chemical, biological and certain soil enzyme properties was studied. Contamination of iron slag particles altered physico-chemical, biological and enzyme properties of soil. While soil pH increased slightly, electrical conductivity, carbon, potassium and phosphorus contents ...

abstract soil, is a reclamable and sustainable source. it is the basis of survival and it’s implication, should be performed on the basis of productivity identification according to scientific and technical rules, we can protect this valuable source, and increase it’s productivity and usage. nowdays, saline soils cover nearly 14.6% of the country area. study areas (kashan’ playa) have saline an...

In order to evaluate the influence of ionic liquid 1butyl-3-methylimidazolium chloride ([Bmim]Cl) on the soil micro-ecological system, the toxicity of [Bmim]Cl to soil microorganisms and its impact on soil physico-chemical properties were investigated. Three soil samples, which were taken from the rape land, nursery land and the broad bean land respectively, were used for this study. The toxici...

Temperate and dry deciduous forest covers major portion of terrestrial ecosystem in India. The two forest types with different dominant tree species differ in litter quality and root exudates, thereby exerting species-specific impact on soil properties and microbial activity. This study aims to examine the influence of forest type or dominant tree species on soil physico-chemical properties and...

Morphological and physiological characteristics of biological soil crusts (BSCs) enhance soil stability and fertility, and influence soil chemistry. However, the effect of BSCs on soil physico-chemical properties may vary depending on taxa (cyanobacteria, lichen, bryophytes) and species, and be susceptible to soil surface disturbance. We examined a wide variety of soil physico-chemical properti...

Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...
