Soil science covers soil genesis, classification, mapping, physical and chemical properties, biology, fertility, and the management of soils.
Soil science is the interdisciplinary study of soil as a natural resource at Earth's surface. Its scope includes soil formation, classification, mapping, and the physical, chemical, biological, and fertility properties of soils, as well as how these properties affect soil use and management. The field draws on knowledge from geology, biology, chemistry, ecology, agronomy, geography, engineering, hydrology, and environmental science. The discipline has two principal branches: pedology, which examines soils in their natural settings and development, and edaphology, which focuses on soils in relation to plant growth and human uses. Modern soil science also addresses climate change, greenhouse-gas emissions, carbon sequestration, biodiversity, land degradation, water quality, sustainable productivity, waste treatment, restoration, and digital soil mapping. Its applications range from agricultural management and soil surveys to environmental protection, hydrology, archaeological interpretation, and the conservation of land resources.
Soil science covers soil genesis, classification, mapping, physical and chemical properties, biology, fertility, and the management of soils.
Pedology studies soil formation and characteristics in natural landscapes, while edaphology studies soil in relation to plants, agriculture, and other uses.
The field is strongly interdisciplinary, involving soil physics, chemistry, biology, hydrology, geology, ecology, agronomy, and environmental science.
Major modern concerns include soil degradation, climate change, greenhouse gases, carbon storage, biodiversity, food production, water quality, and sustainable land use.
Soil science is applied to land productivity, waste treatment, environmental protection, restoration of damaged land, soil surveying, digital mapping, and hydrological research.
The study of soil as a natural resource, including its formation, properties, classification, distribution, and management.
The branch of soil science concerned with soil formation, classification, morphology, and distribution in natural settings.
The study of soil in relation to plant growth, agriculture, and other soil-dependent uses.
The global soil layer that forms the interface among the atmosphere, biosphere, hydrosphere, and geosphere.
The classification and geographic representation of soil types and properties across an area.
The systematic organization of soils into groups based on their characteristics, formation, and properties.
The capacity of soil to provide essential nutrients and suitable conditions for plant growth.
The ability of soil to perform functions such as supporting productivity, regulating water, sustaining biodiversity, and maintaining environmental health.
The use of geographic information systems, remote sensing, and quantitative methods to predict and map soil properties across space and time.
The study of water movement, storage, and distribution within soils and soil landscapes.
