During 2009–10, the presence of ascomycetous species in soil was studied in Fars province. Isolates were recovered from soil using modified Czapek (Raper et al. 1973), malt extract agar (MEA) and potato dextrose agar (PDA). Teleomorphic characteristics such as morphology of ascocarps, asci, ascospores and anamorphic characteristics such as conidiophores, phialides, conidia and chlamydospores we...
The aim of this study is evaluation the effect of soil, sludge and wastewater on growth characteristics (height, number of leaves and fresh weight) of and plant. For this purpose, 3 sludge treatment, 2 type of soil and 4 levels of irrigation and SPSS 18 were used. The results showed that in all three characteristics of plant growth, increasing height in crop soil is more than the Sejzy soil. In...
The soil quality concept evolved throughout the 1990s in response to increased global emphasis on sustainable land use and with a holistic focus emphasizing that sustainable soil management requires more than soil erosion control. The concept includes two areas of emphasis—education and assessment—both based soundly on principles of soil science. Soil quality test kits, farmer-based scorecards,...
Generally, the evaluation and assessment critical condition of rill formation are useful for a better understanding of soil erosion processes. The inherence characteristics of soils, which have much dynamic variations on the hill-slopes and are affected by rill formation, are the soil critical shear stress and soil erodibility factors. This study aims to assess experimental rill incision thre...

Tropical forests store large amounts of biomass despite they generally grow in nutrient-poor soils, suggesting that the role of soil characteristics in the structure and dynamics of tropical forests is complex. We used data for >34 000 trees from several permanent plots in French Guiana to investigate if soil characteristics could predict the structure (tree diameter, density and aboveground bi...
Berseem (Trifolium alexandrinum) is one of the main fodder crops of Punjab, India. But due to the heavy metal contamination of agricultural soils by anthropogenic activities, there is rise in metal bioaccumulation in crops like Berseem. In addition to human influence, heavy metal contents in soil are highly dependent on soil characteristics also. Therefore a study was conducted in areas having ...
BACKGROUND Soil characteristics have been hypothesised as one of the possible mechanisms leading to monodominance of Gilbertiodendron dewerei in some areas of Central Africa where higher-diversity forest would be expected. However, the differences in soil characteristics between the G. dewevrei-dominated forest and its adjacent mixed forest are still poorly understood. Here we present the soil ...
Soil moisture is one of the most important climatic parameters playing an important role in the global climate system. Soil moisture can be derived from in-situ measurements as well as remotely sensed observations. However, these measurements typically lack the spatial and/or temporal resolutions necessary for modeling and applications. Land surface models (LSM) can be used to simulate the land...
