The Irrometer suction lysimeter or SSAT

It allows extraction of soil water samples for measurement of nitrate levels, salinity, EC, and other chemical elements

It allows the grower to adjust the rate and timing of fertilizer applications, resulting in increased production with decreased fertilizer and water consumption and reduced nutrient leaching.

SSAT‘s are available in standard length of 24″ and include a single suction line, stopper, and finger clamp. Tubes are available with either a standard 1 bar ceramic tip for use in medium to heavy soils, or with a Low Tension (“LT”) ceramic tip for use with lighter soils and potting media.
