Soil Texture Test (Qualitative Test)

To do this test you must take a small moist wad from the sample and squeeze it between your thumb and forefinger. If the soil is not moist, add a little water to it and form a small ball. If the soil feels gritty, it is mostly sand. If it feels sticky, then you have mostly clay. If it feels neither gritty nor sticky, then you have mostly silt. If you can squeeze out a long, unbroken ribbon you have clay.
Our soil sample was sticky and could easily be rolled into a ball. When the soil was being rolled into a ball, a few small, gritty pieces were falling off. Our soil sample was most likely silty loam.

The following picture is of our soil ribbon after a small amount of water was added to make the soil more able to be made into a ribbon
