One of the most important pieces to H2O’s success is the Sentek Soil Moisture Sensor (SMS). A capacitate resistor, it measures soil in volumetric inches. This in combination with Phases 1-3 base data provides expected outcomes when irrigating with initial targets set as part of Phase 3.
But the best part? If any part of these sensors is damaged, the broken piece can be replaced rather than having to purchase an entire new probe. We currently have dozens of sensors that have been in service for over a decade.
“My sensor isn’t working” is a common issue when growers install sensors into an environment that may or may not be representative of the field. H2O Optimizer identifies the variability within your field beginning with Phase 1 Variability Mapping.
In most cases, in fields larger than 40 acres, two sensors are required to accurately characterize the field’s variability. Sensor locations are identified in Phase 3.
The greatest limiting factor to managing limited water supplies is the lack of irrigation system automation. Although 12, 24, 36 and 48-hour irrigations are convenient for irrigation scheduling, they are rarely the correct irrigation durations. Additionally, lighter soils require more frequent shorter duration than heavier textures requiring low frequency with longer durations.
