Which field studies soil as a natural resource, including its formation, classification, mapping, and properties?

• A. Soil Science
• B. Aquaculture
• C. Remote Sensing
• D. Cover Cropping

Answer: (A)

Soil science studies soil as a natural resource, including how it forms, how it is classified, how we map it, and what its physical, chemical, and biological properties are. Soils develop through pedogenesis—influenced by parent material, climate, living organisms, topography, and time—leading to distinct soil types that are classified for consistent communication. Mapping builds soil surveys and maps that show where different soils occur, guiding land use, agriculture, and engineering decisions. Understanding soil properties covers texture, structure, porosity, water-holding capacity, pH, nutrient availability, and biological activity, all of which influence fertility and sustainability. Other fields don’t focus on soil in this way: aquaculture centers on raising aquatic organisms; remote sensing is a tool used across disciplines and isn’t the study of soils by itself; cover cropping is an agricultural practice aimed at protecting and improving soil, not the field that studies soil as a resource.
