Managing water wisely

The Field Scout TDR series has two volumetric water content modes: one for standard soils and one for higher clay soils. In volumetric water content (VWC) mode, the meter converts a measured electrical signal into percent soil moisture content using an equa28d1tion valid over a wide range of mineral soils.

The Field Scout TDR series has two volumetric water content modes: one for standard soils and one for higher clay soils. In volumetric water content (VWC) mode, the meter converts a measured electrical signal into percent soil moisture content using an equation valid over a wide range of mineral soils. In irrigation mode, the meter displays a relative water content (RWC) on a scale of zero to 100 corresponding to a user-defined upper and lower soil moisture reference level. Water deficit, the amount of water needed to bring the soil moisture content up to the upper reference level, is also calculated and displayed. The reference levels are easily programmed into the meter with the accompanying software. Create up to two management sites based on the soil types and crop needs. Use the raw reading mode — measurement period in microseconds — to do soil specific calibrations. An internal data logger and RS-232 port allow for use with a DGPS for geo-referenced soil measurements (TDR 300 model only). Includes software and PC cable.
