土壤是影响或控制大多数生物的环境的重要组成部分。土壤科学研究土壤系统，以找到生产食物的最佳方法
Soil forms an essential part of the environment—affecting or controlling most living things. Soil science studies the soil system to find the best ways of producing food, fuel, and fibre while still preserving soil for use by future generations.Soil science draws from biology, ecology, geography, geology and a variety of other natural and life sciences. The soil science program at the University of Saskatchewan provides an in-depth understanding of the physical, biological and chemical processes that occur in soil and the role soil plays in plant production and environmental management.
