"Help yourself to think on your feet in the field"
Single-sided, plastic-coated guide for assisting with soil texturing procedures and assigning a Texture Class using the USDA texture triangle. The Flow Chart uses step-wise procedures (adopted from Foth and others, 1992) for estimating sand, silt, and clay content.
The Flow Chart uses the ribbon method to estimate the fine-grained fraction followed by placing the fraction within the texture triangle to determine Texture Class (ex: sandy loam). The guide provides instruction for determining Subclass (ex: fine sandy loam) and assigning Textural Class Modifiers for rock fragments greater than 2mm (ex: gravelly silt loam) and organic Compositional Textural Modifiers (ex: peaty sandy clay loam).
