WATER MANAGEMENT ▶▶▶
Manufacturer: Dacom Probe: TerraSen Cost: TerraSen basic $ 2,000 (€ 1,860) and TerraSen Pro (with rain gauge) $ 2,323 (€ 2,160)
Description: The TerraSen, which is equipped with a solar panel, communicates every hour through 3G. This advanced soil moisture station measures soil moisture and the soil temperature in five layers of 10 cm, with a total measuring depth of 50 cm.
Manufacturer: Dynamax Probe: ML3 Theta, SM150T soil moisture sensor, and PR2 Profiler soil moisture profile probe Cost: SM150T sensor attached to a SapIP wireless data loggers (complete kit, with so- lar panel included, but not pipe mount, bat- tery and box) and web data access for one year sells for $ 3,392 (€ 3,154)
Description: These probes all use the same technology and provide readings of soil wa- ter content as a percentage or as water by volume. They can be read with most Camp- bell or Delta-T data loggers and are also
Manufacturer: Lindsay Corporation Software: FieldNET Advisor (no probe in- volved) Cost: Starts at $ 450/year per field (€ 418)
Description: FieldNET Advisor is a cloud- based irrigation scheduling system that uses computer models and millions of data points to generate a customised, daily irrigation rec- ommendation. Users enter crop and date in- formation, and the system combines it with soil maps, hyper-local weather information and historical field data. FieldNET Advisor then tracks crop growth and root depth to
Manufacturer: Metergroup Probe: Teros 21 Cost: $ 225 and up (€ 210)
monitor soil moisture and make irrigation recommendations for maximum crop yields.
Description: The Teros 21 measures the di- electric permittivity of a solid matrix to de- termine the water content of the solid ma- trix. The relationship between water content and matric potential, known as the soil mois- ture characteristic curve, is used to calculate the soil matrix potential. This measurement approach, along with the calibration process used in production, makes it possible to measure water potential.
Manufacturer: RioT Technologies Probe: GroPoint Profile Cost: from $ 250 to $ 1,300 (€ 232 to € 1,210)
Description: The GroPoint Profile provides soil moisture (and optionally, temperature) measurements and each sensing element can be configured/calibrated individually to ensure accurate measurements across differ- ent soil types/horizons. Available with differ- ent interfaces, in lengths of 30, 45, 60, 75 and 120 cm. No access tubes or excavation are needed for installation in permanent and temporary installations.

Manufacturer: Sensoterra Probe: Multi-Depth Cost: Multi-Depth starts at $ 799 (€ 743) and Single-Depth at $ 299 (€ 278); both include calibration, web and mobile monitoring tools and a three-year data plan.
Description: The Sensoterra Multi-Depth sensor measures volumetric soil moisture at six different depths, ranging from 4 to 35 inches and soil temperature at 14 inches of depth. An external antenna enables the sen- sor to obtain a strong LoRaWAN signal even with a dense crop canopy. All data can either be accessed in Sensoterra’s own web monitor
