Differentiate the three soil separates (sand, silt, and clay) based on their particle size diameters. Determine the percentages of sand, silt, and clay in selected soil samples using data collected from the hydrometer method of particle size analysis. Estimate the textural class using the texture-by-feel method on selected soil samples.
