METHOD FOR DETECTION OF MOISTURE OF PERSISTENT DROOPING Russian patent published in 1997 - IPC

Abstract RU 2092819 C1

FIELD: microwave measurements, soil analysis in agriculture. SUBSTANCE: method involves passing electromagnetic waves through moist soils and measuring soil refraction index depending on its moisture in microwave band. Resulted graphic function provides value Wt which corresponds to transition point from bound to free water. Moisture of persistent drooping conforms to condition Wdr = 0,93Wt. EFFECT: increased functional capabilities. 2 dwg, 1 tbl
