The objectives of this study were to determine the degree of spatial variability of soil physical properties and variance structure, and to model the sampling interval of alluvial floodplain soils. Soil profiles (n = 209) from 18 parallel transects were sampled with a mean separation distance of...
The soil spatial variability is an important determinant of efficiency of farm inputs and yield. This study was carried out to identify and compare spatial variation of some soil physical properties by geostatistics in alluvial and adjacent colluvial soils formed under ustic moisture regime at G枚...

although inactive, constitute the framework of the soil. They play less important role in physicochemical activities. When coated with clay, these sand particles take very active part in chemical reactions. Sands increase the size of
Spatial Variability Analysis of Soil Physical Properties of Alluvial Soils In 2005-2009 the temporal and spatial dimensions in the six research sites were studied in order to assess the impact of environmental management on change... J Iqbal,JA Thomasson,JN Jenkins,... - John Wiley & Sons, ...
Alluvial soil in Fukaya, locating at a basin of Tone River in Saitama prefecture, has been perceived to be a 'good' soil. Recently, however, some fields in this area were damaged and the drainage efficiency is being degraded. The objective of this study is to investigate and evaluate the ...

Physical and chemical properties of red soils, white rendzina, light chestnut, dark chestnut, grey, black, and recent alluvial soils as mapped by Geze (1956) were compared statistically. No statistically significant differences were found between surface soil (0–15 cm) and upper subsoil (15–...
Relationships Between Petrophysical and Mechanical Properties of Certain Calcarenites Used in Building Article21 April 2021 Introduction Since ancient times, dimensional stones have been used as a material for building infrastructure, buildings of worship and monuments, many of which have become part of ...
