First, add more water to one of the sediment tubes from each site, until the soil is completely saturated and a layer of water about 1 cm deep forms above the surface of the soil.
You will come back to these samples in one hour. Soil particles which are smaller, like clays and clay loams, are more influenced than coarse, sandy soils.
