AGRO 2051 : Lab Exam 1 Notes
Document Summary
Definitions ranging from the largest sand particles to the smallest clay particles. Soil texture relative proportion of sand, silt, and clay in a soil. Soil separates continuum of particle sizes, particle size distribution in soil. Particle density mass of soil solids (oven-dry) per unit volume of soil solids. Bulk density mass of soil solids (oven-dry) per unit of volume of soil. Gravimetric water content mass of water per mass of oven-dry soil (percent) Volumetric water content volume of water per total volume of soil (fraction) Porosity pore volume of total soil volume (fraction) Particle density = mass of oven dry/volume of soil particles. Oven dry mass = air dry mass/(1 + air dry moisture percentage) Net mass of water = (flask + soil + water) - (flask + soil) Air dry mass of soil = (flask + soil) flask. Mass of water = (flask + water) net mass of water.
