Soil provides raw materials for human use and impacts human health directly. The composition of human food reflects the nature of the soil in which it was grown. An example of soil as a source of raw material can be found in ancient ceramic production. The Maya ceramics showed traits inherited from soils and sediments used as raw material. [8]
Soil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from soil by restricting the former term specifically to displaced soil. Soil measuring and surveying device
Human uses of living things, including animals, plants, fungi, and microbes, take many forms, both practical, such as the production of food and clothing, and symbolic, as in art, mythology, and religion.
Other earth materials include soil blocks typically stabilized with a cement additive and produced with forms or compression. Rammed Earth consists of walls made from moist, sandy soil, or stabilized soil, which is tamped into form work. Walls are a minimum of 12″ thick. Soils should contain about 30% clay and 70% sand. [4]
Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.
Land use is an umbrella term to describe what happens on a parcel of land. It concerns the benefits derived from using the land, and also the land management actions that humans carry out there. [1] The following categories are used for land use: forest land, cropland (agricultural land), grassland, wetlands, settlements and other lands.
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.
An anthrosol (or anthropogenic soil) in the World Reference Base for Soil Resources (WRB) [1] is a type of soil that has been formed or heavily modified due to long-term human activity, such as from irrigation, addition of organic waste or wet-field cultivation used to create paddy fields. [2]
