Soil surveys are systematic assessments of soil types and properties, guided by organizations like the USDA NRCS and the National Cooperative Soil Survey. They classify soils based on taxonomy, contributing to global efforts like the FAO-UNESCO Soil Map. Key concepts include soil profiles and horizons, which reveal layers of soil development. Soil health relates to fertility and conservation practices that enhance productivity. Pedologists study soils' characteristics, while groups like the Soil and Water Conservation Society promote sustainable land use and environmental protection, ensuring that soil resources support agriculture and ecosystems effectively.
