12.6. LP/ms - Laboratory miniProbe for soil water content and salinity<br />
measurement<br />
LP/ms (Fig. 66) - is a laboratory miniprobe designed for monitoring changes<br />
in water and salt distribution in soil columns or in soil cores sampled with<br />
standard sampling instrumentation. Several LP/ms can be inserted through the<br />
sidewall of a soil column or a steel sampling cylinder (Fig. 67), thus allowing for<br />
vertical scanning of the instantaneous moisture and electrical conductivity<br />
profiles.<br />

LP/ms - Laboratory miniProbe for soil water content and salinity measurement<br />
Such an array, when combined with s<strong>im</strong>ilarly installed minitensiometers<br />
(LP/p), makes it possible to collect a set of corresponding water content and<br />
matrix potential gradient data from drying or wetting front transition. From this<br />
one can obtain a complete set of the soil unsaturated water flow characteristics, ie<br />
