Plant species, plant community diversity and microbial interactions can significantly impact soil microbial communities, yet there are few data on the interactive effects of plant species and plant community diversity on soil bacterial communities. We hypothesized that plant species and plant community diversity affect soil bacterial communities by setting the context in which bacterial interac...

An overview of the Geospatial Methodologies used in order to assess the Soil Erosion Risk by water. 1.2 The damages on Land are traduced in " Soil Erosion " , " Soil Degradation " and/or " Ecosystem Decline " .. Introduction The Soils constitute one of the most important of the world's natural resources. Life on earth is totally dependent on well management of soils (Agurgo, 1996). Into of the ...

soil, a 3-dimensional component of the landscape, or simply a natural body in a soilscape with a given geopedological setting, was modeled by jenny as s = f (climate, organism, relief, parent material, time). to map such a complex body, the concept ‗pedon’ –the smallest volume that can be recognized as a soil had to be defined. classically, soil is known to function as provider, controller, reg...

Agricultural producers require knowledge of soil water at plant rooting depths,while many remote sensing studies have focused on surface soil water or mechanisticmodels that are not easily parameterized. We developed site-specific empirical models topredict spring soil water content for two Montana ranches. Calibration data sample sizeswere based on the estimated variability of soil water and t...

Soil erosion risk assessment at the watershed of Alqueva is urgently needed to conserve water resources and prevent the accelerated dam siltation. The variation of soil properties is one of the most important reasons for the spatial variability of vegetation cover and erosion. In order to achieve more and better management of rangelands around the largest reservoir of Europe, it is essential to...
