Root-Zone & Atmospheric
Irrigation Telemetry.

Effective irrigation management balances subterranean soil moisture reserves with actual crop transpirational demand. Véraison measures volumetric soil moisture within the active root horizon alongside pyranometer solar radiation, canopy temperature, and relative humidity to help growers make informed scheduling decisions.

Balancing root moisture with atmospheric demand.

Plant water status is never determined by soil moisture alone. A crop in moist soil can still experience acute transient water stress on an arid, windy afternoon when atmospheric evaporative pull outpaces the plant’s vascular uptake capacity.

Below Ground: Root-Zone Moisture

A calibrated soil moisture probe installed directly within the crop’s active root zone tracks continuous hydration, helping identify field capacity and the specific refill threshold for your soil type.

Above Ground: Atmospheric Demand

Irrigation requirements depend directly on atmospheric evaporative pull. Our pyranometer measures incoming solar radiation, while in-canopy temperature and humidity track Vapor Pressure Deficit (VPD).

Regulated Deficit Irrigation (RDI).

In perennial viticulture and tree crops, irrigation is often used strategically to manipulate vegetative shoot vigor and concentrate fruit quality. Véraison provides continuous data to help managers track dry-down trends without crossing damaging stress thresholds.

Stage 01Bud Break to Flowering

Early Canopy Development

Unconstrained Hydration

Ensure adequate root-zone moisture to support uniform shoot elongation, leaf canopy surface area, and healthy flower cluster development without early moisture stress.

Moisture Management ContextCalibrated to maintain soil moisture safely above refill point for the specific soil texture.

Stage 02Fruit Set to Véraison

Regulated Deficit (RDI)

Managed Moisture Moderation

Carefully manage root-zone water availability to arrest excessive vegetative shoot tip growth, directing photosynthetic carbohydrates toward developing berry clusters and skin development.

Moisture Management ContextAllows gradual depletion toward controlled refill levels, monitored to avoid severe stomatal closure.

Stage 03Véraison to Post-Harvest

Ripening & Post-Harvest

Maintenance & Replenishment

Apply measured irrigation to sustain canopy photosynthetic capacity through ripening without diluting fruit solutes, followed by post-harvest root hydration to rebuild carbohydrate reserves.

Moisture Management ContextTargeted irrigation based on prevailing heat waves, solar radiation, and soil moisture drawdown.

Direct readings from the active root zone.

Surface soil dries quickly under sun and wind exposure, which can mislead visual row inspections. Conversely, deeper subsoil may retain moisture that remains out of reach if rooting depth is constrained.

Véraison’s soil moisture probe is installed directly in the active root absorption zone of the crop. Continuous volumetric water content data helps managers observe when irrigation pulses reach the root zone and track the rate of moisture consumption over time.

Field Capacity Tracking: Observing infiltration curves helps determine when irrigation has adequately wetted the root horizon.

Refill Threshold Identification: Monitoring the inflection point where root moisture extraction rates begin to slow.

Fertigation Management: Keeping applied water and soluble fertilizers within the active root horizon rather than leaching past it.

Water efficiency, energy timing, and soil aeration.

Water availability and pumping electricity costs require disciplined management. In-row telemetry addresses three fundamental operational objectives:

Preventing Deep Drainage & Nutrient Leaching

When irrigation runs longer than the soil can hold in the active root horizon, excess water drains past root depth—taking expensive soluble nitrogen, potassium, and micronutrients into groundwater.

Operational Advantage:Helps identify precise wetting front infiltration times so pumps can be stopped once root depth is replenished.

Optimizing Pumping Run-Times & Energy

Running irrigation pumps on fixed schedules often leads to over-watering during cool, humid weeks or under-watering during intense heat spikes. Aligning runtime with actual microclimate demand helps avoid wasted energy.

Operational Advantage:Enables managers to plan irrigation sets to align with off-peak electrical utility tariffs and actual evaporative losses.

Preserving Root Aeration & Soil Health

Consistently waterlogged soils displace oxygen from soil pores, causing root asphyxiation, reducing nutrient uptake efficiency, and creating conditions favorable for soil-borne root rot pathogens like Phytophthora.

Operational Advantage:Allows natural soil dry-down cycles between irrigation sets to maintain healthy soil respiration and root vitality.
