A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
Soil structure describes the arrangement of the solid parts of the soil and of the pore spaces located between them (Marshall & Holmes, 1979). [1] Aggregation is the result of the interaction of soil particles through rearrangement, flocculation and cementation.
The formation was first described as part of the Floresta Series by Olsson and Carter in 1939. The current definition was given by Botero in 1950. [2] The formation is named after the vereda Cuche of Floresta, Boyacá, where the formation outcrops. [3]
Soil is a major component of the Earth's ecosystem.The world's ecosystems are impacted in far-reaching ways by the processes carried out in the soil, with effects ranging from ozone depletion and global warming to rainforest destruction and water pollution.
Loreto Formation (Spanish: Formación Loreto) is a sedimentary formation of Late Eocene age in the southernmost Magallanes Basin.It overlies the Leña Dura Formation and the contact with an overlying formation is not observed. [1]
The Chipaque Formation (Spanish: Formación Chipaque, K 2 cp, Kc) is a geological formation of the Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes.The formation is also described as Gachetá Formation, named after Gachetá, in the area of the Llanos foothills of the Eastern Ranges.
The soil is home to a large proportion of the world's biodiversity.The links between soil organisms and soil functions are complex. The interconnectedness and complexity of this soil 'food web' means any appraisal of soil function must necessarily take into account interactions with the living communities that exist within the soil.
The Lopez de Bertodano Formation is a geological formation in the James Ross archipelago of the Antarctic Peninsula.The strata date from the end of the Late Cretaceous (upper-lower Maastrichtian stage [1]) to the Danian stage of the lower Paleocene, from about 70 to 65.5 million years ago, straddling the Cretaceous-Paleogene boundary.
