Due to Mediterranean climate conditions and low water inputs, traditional management is based on reduced tree density, canopy size control by pruning, and intensive weed control. Weed contr ...[Read More]
Soils at Imaggeo: Patterned sand
Alma de Groot, The Netherlands Dunes are wind-generated accumulations of sand particles present in desert or coastal land. Sand dunes have smooth and uniform forms, although geometry may be highly variable. The size of particles of sand dunes is highly concentrated around 0.2 mm in diameter due to wind transportation. The pattern showed in the picture is the result of the formation of aeolian dune ...[Read More]
