Soil texture directly influences the capacity of a growing plant to secure air and water.
Soil Texture Test Kit consists of three calibrated conical tubes, a plastic tube stand, dispersing reagent and a flocculating reagent to speed the settling of finely divided particles. Instructions describe methods for breaking down soil samples into their sand, silt and clay fractions. Sand settles in 30 seconds, silt in 30 minutes and clay within 24 hours.
