The document describes two methods for determining soil texture in the field: 1. The "feel method" involves moistening soil and examining its properties like stickiness, graininess, and ribbon formation to estimate clay, sand, and silt content. 2. The "runoff method" involves saturating soil with water and counting how many rinses are needed until the runoff is clear to estimate total silt and clay content. Results from both methods can be used to classify the soil sample on a texture triangle.
