LaMotte Water & Soil pH - Manual (Page 14)

ROOT HAIRS: Very small roots of a plant which take in nutrients from
the soil solution.
SAND: The largest soil particle. Sandy soil feels gritty when rolled
between the fingers and is formed by the erosion of rock material.
SCALE: A hard crusty deposit which may be formed on the inside of pipes
and valves; usually a result of calcium and magnesium in the water.
SETTLING RATE: The amount of time required for particles in solution
to settle.
SILT: The mid-sized soil particle. Silty soil feels silky to the touch and is
usually found in combination with sand and/or clay.
SOIL TEXTURE: The relative amounts of sand, silt, and clay in soil.
SOLUTION: One or more substances dissolved in a liquid.
STUNTING: The lack of normal growth and development of plant parts.
May be an indication of mineral deficiency.
WEATHERING: The process of disintegration or wearing down of
substances by natural forces, including wind, rain, freezing. Weathering
produces smaller rock particles which form the basis of soil.
