TEXTURE
Component 2: Texture
Students will determine the texture class, and also estimate sand, silt, and clay contents on soil samples. The soil samples are from disclosed or undisclosed locations throughout the USA. The samples have been sieved and dried. The amounts of sand, silt, and clay have been identified on each sample using the pipette and/or hydrometer methods. Each participating coach will receive a set of texture samples, but will not be informed of the measured values until after the competition. The samples will include practice sample and competition samples. The coach will administer the practice and competition for the hand texturing component. The texture triangle is the only allowable resource for this portion of the contest. Student scores will be sent to the contest committee by the indicated due date.
