SOIL AND WATER SCIENCE: LABORATORY METHODS SOIL PHYSICS COMPONENT Website:http// Course Topics: Lectures 1. Soil Parameters Relationship between water content (by volume and weight), bulk density, and particle density Soil water content: determination of gravimetric and volumetric water content. Tools for soil water content and matric potential determinations. Soil moisture release curves. Particle density: total porosity and bulk density as determinants of particle density. 2. Water Movement in Soils: Water Content and Potential Gravitational potential, matric potential, total potential, and the gradient (force for water movement) Darcy’s equation
