A METHOD OF MICROWAVE SOIL MOISTURE INVERSION WITHOUT DEPENDENCE ON THE FIELD MEASUREMENT DATA
LUT AIEM Optimal effective roughness Pixel scale ASAR
2018/5/14
In the process of retrieving soil moisture (Mv) by active microwave, surface roughness is an important parameter affecting the accuracy of mv retrieval.Using effective roughness to replace the origina...
Evaluation of ground penetrating radar and vertical electrical sounding methods to determine soil horizons and bedrock at the locality Dehtare
geophysical method parent rock soil layer soil survey
2015/3/9
Recently, geophysical methods have been widely used in many fields including pedology. Two of them, ground penetrating radar (GPR) and vertical electrical sounding (VES) were employed at the Dehtá"...
Effects of soil depth spatial variation on runoff simulation, using the Limburg Soil Erosion Model (LISEM), a case study in Faucon catchment, France
conditional simulation Faucon hydrograph kriging LISEM soil depth
2015/3/5
Soil depth is an important parameter for models of surface runoff. Commonly used models require not only accurate estimates of the parameter but also its realistic spatial distribution. The objective ...

Each society wishes to create favourable living conditions for its members. Life quality criteria are formulated in different ways by various societies or individuals, depending on the given geographi...
Soil water regime estimated from the soil water storage monitored in time
ecology classification soil water regime soil water content monitoring soil water storage
2015/2/3
During the vegetation season, the water storage in the soil aeration zone is influenced by meteorological phenomena and by the vegetated cover. If the groundwater table is in contact with the soil pro...
Predicting soil erosion in oriental spruce (Picea orientalis (L.) Link.) stands in Eastern black sea region of Turkey
Soil loss tolerance tree line timberline subalpine zone
2011/1/12
Human induced pressures on the natural resources are still in progress and the conservation efforts, too. The need for sufficient knowledge and data for the decision makers is obvious. This study is a...
Evaluation of methods for measuring soil organic carbon in West African soils
Soil organic carbon loss on ignition dichromate oxidation
2011/1/12
Increased interest in implementing projects in the Sahel region of Africa for sequestration of atmospheric carbon dioxide in soil organic matter has intensified the need for methods that accurately me...
A soil loss estimation of crop fields on a local scale was carried out using the Universal Soil Loss Equation (USLE) and Geographic Information System (GIS) tools. The study site covering 3,009 ha in ...
Seasonal Changes in N2 Fixation Activity and N Enrichment in Paddy Soils as Affected by Soil Management in the Northern Area of Japan
gluten index PCR marker
2009/9/10
We studied single seed descent lines derived from the Kitakeiharu 717 (KKS 717) / Grandin cross. The presence of a B subunit of KKS 717-specific low-molecular-weight-glutenin subunit (LMW-GS) signific...
Soil scientists often face the dilemma of wishing to study soil in remote areas because they are ideal places to study soil formation and distribution under natural conditions, but mapping them requir...
