Soil Composition Analysis: Uncovering Sand, Silt, and Clay Percentages

Joe from Grow It Build It explains how to determine the composition of soil by measuring the percentages of clay, silt, and sand. The video provides a step-by-step guide on preparing soil samples, using a jar test to separate soil components, and calculating the results. Joe also discusses how to improve soil quality based on the test results, with tips on using compost and other amendments.
