n. The sub-discipline of soil science that studies the physical properties of the soil, with particular emphasis on soil moisture potential, water movement and solute transport.
Soil physics is the study of soil physical properties and processes. It is applied to management and prediction under natural and managed ecosystems. Soil physics deals with the dynamics of physical soil components and their phases as solid, liquids, and gases. It draws on the principles of physics, physical chemistry, engineering, and meteorology. It is especially important in this day and age because most farmers require an understanding of agroecosystems. Soil physics applies these principles to address practical problems of agriculture, ecology, and engineering.
