List three (3) tests that can be done on a soil sample and their significance.​

Moisture determination - one of the most important and most widely used measurements in the processing and testing of foods. Since the amount of dry matter in a food is inversely related to the amount of moisture it contains, moisture content is of direct economic importance to the processor and the consumer.

Atterberg limits tests - establish the moisture contents at which fine-grained clay and silt soils transition between solid, semi-solid, plastic, and liquid states. ... Casagrande refined and standardized the tests, and his methods still determine the liquid limit, plastic limit, and shrinkage limit of soils.

Soil Compaction Testing - a crucial step in the construction process. Ground that has not been properly compacted can be detrimental to the structural integrity of buildings, retaining structures, roads and pavements, just to name a few. Essentially, proper soil integrity could make or break your structure
