Papers of chemical-physical properties — Weaving of the soils of the Emilia-Romagna plain — layer 0-30 cm, scale 1:50.000

The weaving map represents the range distribution of the granulometric fractions classified according to the USDA methodology (International Standard, ref. Department of Agriculture United States). Each cell is assigned a % value of sand, silt, clay, skeleton and USDA weaving class. Each parameter shall be accompanied by a reliable assessment of the estimated value. The representation of the territory takes place through a mesh structure consisting of cells with 500 m side. The attribution of the values to the cell is the result of a geostatistical analysis applied to the Plain soil map (scale 1:50,000) and refers to the first 30 cm of soil.
