Agricultural land is typically managed based on visible plant life at the expense of the belowground majority. However, microorganisms mediate processes sustaining plant life and the soil environment. To understand the role of microbes we first must understand what controls soil microbial community assembly. We assessed the distribution and composition of prokaryotic communities from soils repr...

Soil science is a relatively new discipline which has mainly developed since the 1880s. It uses terms, methods and processes borrowed from other basic disciplines like climatology, geology, chemistry, physics and biology, but with a direct application to soils. At present, it is difficult to speak about one single science but as soil sciences, as they cover several fields including: pedology (o...

More attention has been paid to estimating soil nutrient status, along with a sharp decrease in total farmland acreage, especially in Beijing Municipality. However, traditional site-specific investigation makes it impossible to apply it to large scale monitoring. The objective of this study was to evaluate and classify soil nutrient status using advanced 3S (global positioning system, GPS; remo...

the aim of this research is to classification of soil seed bank in populus caspica protected area. the study of above ground vegetation and soil seed bank were carried out with braun-blanquet and seedling emergence method respectively. results showed that size of soil seed bank in upper layer (713 seeds per m2) were significantly lower than depth layer (1163 per m2) but species richness from 42...

Due to its low permeability, a clay liner is the main material used in solid waste disposal landfills. It is exposed there to various chemical, biological, and physical events, and the clay liner is affected by the resulting leachate. For this reason, when attempting to define the geotechnical characteristics of clay liners, the use of distilled water or tap water is far from being representati...

The mixed pixels in remotely sensed data are one of the main error sources resulting in poor classification accuracy using traditional classification methods. In order to improve classification accuracy, linear spectral mixture analysis (LSMA) has been used to handle the mixed pixel problems. This paper aims to achieve an appropriate processing routine of LSMA through the comparison of classifi...

knowledge about spatial soil variation in terms of measured pedodiversity offers the possibility to estimate the quality and variance within a soil map. diversity indices and abundance distribution models are statistical tools which ecologists have applied for decades for analyzing the intrinsic regularities of various ecological entities. in this study relationships between soils evolution, la...

This paper aims to investigate the potential of using soil-landscape pattern extracted from a soil map to predict soil distribution at unvisited location. Recent machine learning advances used in previous studies showed that the knowledge embeddedwithin soil units delineated by experts can be retrieved and explicitly formulated from environmental data layers However, the extent to which the mod...

This study pursues the mapping of the distribution of topsoils and surface substrates of the Lake Manyara area of northern Tanzania. The nine soil and lithological target classes were selected through fieldwork and laboratory analysis of soil samples. High-resolution WorldView-2 data, TerraSAR-X intensity data, medium-resolution ASTER spectral bands and indices, as well as ENVISAT ASAR intensit...
