In temperate forest ecosystems, soil acts as a major sink for atmospheric N deposition. A 15N labeling experiment in a hardwood forest on calcareous fluvisol was performed to study the processes involved. Low amounts of ammonium (15NH4 +) or nitrate (15NO3 ...
This paper presents the results of a two phase Euler-Euler simulation of seepage flow through granular media for upward flow conditions in soils. The simulation first deals with the fluidization process in a stable granular soil. The first fluidization in ...
SABRE (Source Area BioREmediation) is a public/private consortium of twelve companies, two government agencies, and three research institutions whose charter is to determine if enhanced anaerobic bioremediation can result in effective and quantifiable trea ...
The coherent description of water flow and solute transport within heterogeneous hydrologic media (e.g., hillslopes or entire catchments) in response to external rainfall forcings represents a challenge in hydrological modeling. In this paper the mechanism ...
Systematic evaluation of different trickle irrigation design and management scenarios must consider the impact of a particular design on crop response at different soils, climatic conditions, and management options. Anecdotal evidence suggests that differe ...
In temperate forests, soils are the main sink for atmospheric N deposition. The main processes proposed for N retention are microbial and abiotic immobilization in soil organic matter. The relative importance of these processes as well as the kind of resul ...
Since a few decades, the balance of the nitrogen (N) cycle has been deeply disturbed by human activies. The global impact of these activities on the N cycle can be described as a doubling of the transfer from the vast and unreactive atmospheric pool to bio ...
More than ever before, a compelling need exists for an encyclopedic resource about soil – the rich mix of mineral particles, organic matter, gases, and soluble compounds that foster both plant and animal growth. Civilization depends more on the soil as hum ...
We describe the on-going design and implementation of a sensor network for agricultural management targeted at resource-poor farmers in India. Our focus on semi-arid regions led us to concentrate on water-related issues. Throughout 2004, we carried outa su ...
We examine the effect of natural differences in soil temperature at two locations distant by approximately 500 m in the frozen scree of La Plagne en Chartreuse (Savoy, France). We determined humus properties, soil organisms and biologically mediated soil-f ...
