What is Plantarray

Plantarray is a high-throughput, multi-sensor physiological phenotyping gravimetric-based platform.

The system continuously and simultaneously measures the momentary-varying water flux in the Soil-Plant-Atmosphere (SPAC) for each plant in the array under varying ambient conditions.

The Plantarray phenotypic approach is driven by the linear correlation between stomatal conductance and transpiration (water-use, H2O) to plant productivity (CO2 assimilation), which indicates the plant performance in high correlation to yield results.

Plantarray puts the plant-environment puzzle together

The direct measurement of plant water balance and biomass gain that is determined for the root and shoot enables the calculation of the plant’s physiological profile and their response to the dynamic environment.

The system provides a quantitative comparison of the plant response to different treatments and the precise prediction of plant growth and productivity in an efficient, easy-to-use, non-invasive manner.

Plantarray measures, at high frequency, the plant response to the dynamic environmental conditions

Key Benefits

  • Deep insights into plant-environment interactions, in particular under stress.
  • High predictability of plant productivity in varying environments for stress-resistance and early stress detection in plant breeding.
  • Grow more with less - optimize irrigation, nutrients and bio-stimulants levels.

Key Features

  • Precise direct measurements of key yield-related traits
  • Control irrigation via various modes - time, weight, soil moisture and daily transpiration.
  • Automated and simultaneous measurement of individual plants in the array.
  • High spatial and temporal resolutions.
  • 24/7 continuous measurement.
  • Unique feedback-based irrigation control.
  • Cloud-based real-time statistical analytics.
  • Whole plant, non-invasive measurements.
  • Suitable to most plants, soil types and growth stages.

Over a Decade in The Making

The reliable and robust Plantarray system is the outcome of over 10 years’ research using weighing lysimeters (gravimetric system) to monitor different plant responses under varying environmental conditions.

Our long-term experience is implemented in every part of the system:

Specially designed drainage container

  • Highly robust – No moving parts
  • Wide pot volume range (1.5-60L)
  • Four drainage positions
  • Prevents leakage of water on the lysimeter surface
  • Enables water and root measurements without affecting the plant and the experiment.

Each pot is placed on a highly accurate load cell. The load cell is connected to a control unit that continuously measures the pot weight 24/7, and enables further calculation of its physiological traits.

Custom made control unit

  • Contains two self-controlled valves for maximum irrigation and fertigation flexibility
  • Enables automated, personalized, plant-specific feedback irrigation
  • Each control unit is built to hold up to four additional sensors
  • Although all interconnected, failure in one unit does not affect
    the others
  • Reduces noise and the requirement for lengthy cables
