Soil science studies soils and their interaction with living things, especially plants. This sub-discipline is further cleaved into two branches, Pedology and Edaphology. Soil Science inspects the process of soil formation as well as its classification. It is an interdisciplinary field where engineers, biologists, microbiologists, sanitarians, and archaeologists contribute to further the knowledge in this field making its scope of employability massive. Soil Science draws knowledge and concepts from other disciplines like Geology, Natural Resource Management, Sustainable Development, and Biochemistry. Students pursuing Soil Science degrees gain knowledge on topics like soil conservation, crop rotation, soil fertilizers, water management, and crop tillage to name a few.

Soil scientists study soil as a natural resource and try to sustain it as well as bring to light the process of soil preservation, in order to prevent land degradation. Soil scientists have a colossal area of employment opportunities as land degradation drastically impacts our agriculture in addition to our economy posing a threat to the national revenue. They work with farmers to protect the sustainability of soil, eventually protecting our flora and fauna, as healthy land is indispensable to both. The restoration of the quality of land and prevention of land degradation is a very rudimentary requirement that impacts huge areas of human pursuit making its reach very elaborate and significant.
