USCS Calibrated Baseline Soil Kit

This kit is the most powerful tool ever designed for learning how to classify soil with accuracy and confidence! This unique collection of soil samples is classified using not only the USDA and USCS, but includes instructions and helpful hints for simplifying classification procedures in the field.

Includes:

5 Soil Samples, 200+ ml each.
Lab Summary Sheet showing particle size curve data and Atterberg Limits.
Sample Summary that describes both the USCS lab and field classification for each sample, plus a comparison of between samples that explains how each may be differentiated from the other according to both USCS and USDA; also includes a description of the source and preparation for each sample.
USDA triangle showing textural results.
Field Guide for Soil and Stratigraphic Analysis.
USDA Soil Texturing Field Flow Chart.
Exercise Sheet for USCS classification.
Exercise Sheet for USDA textures.
3 double-sided laminated field sheets of 'Helpful Hints'.
Plastic jar containers with lids and labels.

See and feel the primary baseline USCS soil classifications.
Feel the contrast between SILT (ML), LEAN CLAY (CL) and FAT CLAY (CH).
See and feel each fine grained sample without interference from secondary sand fractions.
Learn to differentiate WELL GRADED SAND (SW) from POORLY GRADED SAND (SP) in the field.
Practice classifying soil accurately, efficiently and with reproducible results.
See and feel soil samples that plot "on the corners" of the USDA triangle.
Improve the reliability of your USDA soil texturing skills.
Learn the contrasting differences between soil texturing and soil classification procedures.
