Thematic maps are one of the most common tools for representing the spatial variation of a variable. They are easy to interpret thanks to the simplicity of presentation: clear boundaries define homogeneous areas. However, especially when the variable is continuous, abrupt changes between cartographic units are often unrealistic and the intra-unit variation is hidden behind a single representative...
A geostatistical analysis assumes some form of stationarity of the variable under study, but different types of stationarity exist and often spatial data exhibit some form of nonstationarity. However, most studies assume one type of nonstationarity and consequently apply one type of interpolation method within the study area.A study area of 8x18-km area was selected because it was expected to contain...
Soil organic matter contents (SOM) of soils of the Semiarid Pampas of Argentina (SAP), mostly Entic Haplustolls, increase with the amount of silt+clay, but it is still not known how soil texture affects its qualitative composition in interaction with climatic and management conditions. Because of that the organic matter content of the following aggregate size fractions were determined: <2000 μm...
