Plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. The aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including Hordeum bulbosum, Poa bulbosa, Bromus tectorum. First, soil samples were taken in the depth of 0-3...

Dielectric constant values of the samples of soil of Alwar (at various moist states) have been calculated using wave guide cell method at a single microwave frequency 9.78 GHz at 33C. The Backscattering coefficients for rough and bare soil surfaces 0 soil σ are calculated by Small Perturbation Model (SPM). Fresnal reflectivity of the soil surfaces which is an input parameter for SPM is calculat...

climate changes and global warming are considered as very important challenges of sustainable development. carbon sequestration is the easiest and cheapest way to reduce the greenhouse gases, especially carbon which constitutes the largest portion of them. in the present study, the potential of carbon sequestration in four plant species of atriplex canescens, haloxylon persicum, artemisia siebe...

Diagnosis of soil salinity and its spatial variability is required to establish control measures in irrigated agriculture. This article shows the usefulness of electromagnetic (EM) and soil sampling techniques to map salinity. We analysed the salinity of a 1-ha plot of surface-irrigated olive plantation in Aragon, NE Spain, by measuring the electrical conductivity of the saturation extract (ECe...

The aim of our study was to determine the prevalence of keratinophilic and keratinolytic fungi in the soil of recreational areas in Lodz, with a particular emphasis on species potentially pathogenic for humans. The material consisted of 104 soil samples collected from the surface layer and 10-15 cm below the surface at 26 recreational areas in Lodz. Soil samples were inoculated on Sabouraud, Cz...

Aluminum (Al) toxicity imposes a significant limitation to crop production in South Western Australia. This paper examines the impact of surface-applied lime and gypsum on soil solution chemistry short term (1 year) long-term (10 years) water limited environments. In experiments, we measured using paste extract profile samples collected depth 50 cm. We then used chemical equilibrium model MINTE...

heavy metals are very important from environmental consideration due to their toxicity and accumulative properties. the aim of this study is the evaluation of spatial distribution of cr, co and ni in the surface soils of hamadan province. for this purpose, the surface soil samples (0-20 cm) were collected using systematic random sampling method and the concentration of heavy metals and some of ...
