This paper describes the findings of selenium measurement in three types of soil (semigley, pseudogley and hypogley) and in wheat grain cultivated in these types of soil in the vicinity of Koprivnica using hydrid atomic absorption spectrometry. The results showed relatively low selenium levels in all three types of soil (145-333 micrograms Se/kg dry weight) as well as the wheat grain (22-62 mic...

Contamination of the environment in Kuwait occurred in 1990-1991 during the Iraqi invasion and due to explosion of more than 700 oil wells. Oil contamination caused serious damage to the environment. This study was conducted to estimate the extent and volume of contaminated soil by using remote sensing, GIS application and field survey.. A map of the area was developed by GIS showing four types...

Countermeasures to urban flooding should consider long-term perspectives, because climate change impacts are unpredictable and complex. Urban green spaces have emerged as a potential option to reduce urban flood risks, and their effectiveness has been highlighted in notable urban water management studies. In this study, flooded areas in Seoul, Korea, were divided into four flooded area types by...

Two Streptomyces griseus strains were isolated from different soil types. S. griseus CAG17 strain was isolated from an agricultural area with low organic matter but rich in phosphorus content and S. griseus 26K strain was isolated from a forest area rich in organic matter with a low phosphorus content. The survival and metabolic activity of these isolates were studied in dynamic sterile soil mi...

The spatial extent of the transported materials from three road types was studied in forest soil and vegetative communities in Vermont. Hypotheses were two-fold: 1) soil chemical concentrations above background environment would reflect traffic volume and road type (highway>2-lane paved>gravel), and 2) plant communities close to the road and near roads with greater traffic will be disturbance-t...

Information on variations in crop yield among farmer fields in a specific area and theircausal factors is important for efficiently targeting efforts to increase production of the crop inthe target area. This study determined the yield variations and their causal factors for sugarcanegrown in the service area of a sugar mill in Northeast Thailand. Two villages with the dominantsandy and clayey ...

Objective: Soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. Organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure. So, this research has been done for achieving this purpose. Methods: This...

Accurately quantifying soil organic carbon (SOC) is considered fundamental to studying soil quality, modeling the global carbon cycle, and assessing global climate change. This study evaluated the uncertainties caused by up-scaling of soil properties from the county scale to the provincial scale and from lower-level classification of Soil Species to Soil Group, using four methods: the mean, med...

Soil type maps at the scale of 1..1 000 000 are used extensively to provide soil spatial distribution information for soil erosion assessment and watershed management models in China. However, the soil property maps produced through conventional direct linking method usually suffer low accuracy as well as the lack of spatial details within a soil type polygon. This paper presents an effective m...
