Populus tremula requires drier soil, and is therefore not found in the same biotopes as S. lapponum (Reidar Elven pers. com.). We have also made a comparison with other Saperda species from Europe, Asia (Siberia) and North America, with special emphasis on related species in the ...
Soil structure can be defined as the arrangement of primary mineral and organic particles of soil into secondary units called aggregates (Dexter, 1988). Therefore, soils can be seen as a heterogeneous mixture of primary particles (sand, silt and clay), which are organized at several ...
For soils, these terms have the following meaning: • Identification is the process of determining which components exist in a particular soil sample, i.e., gravel, sand, silt, clay, etc. • Description is the process of estimating the relative percentage of each component to prepare a ...
