Arable Mark 2

The Arable Mark 2 is a canopy sensor and weather station, collecting up to 40 different climate and plant metrics, such as evapotranspiration, NDVI, and crop water balance.

Hub Highlights:

Installs in minutes, deploys with the push of a button, and requires no maintenance.
Collected data accessible on Arable's Web and Mobile apps and via API integration.
Arable Bridge, sold separately, allows for integration of auxiliary sensors such as anemometers, soil moisture probes, and pressure switches.

Data Collection

Sample Size

Usability and performance

How does the IDSS appear in the grower's field and how often can/should the user interface with the IDSS?

The Mark 2 appears as a small above canopy sensor tower (looks like a small meteorological station) and its height depends on the height of the cropping system. Users can monitor sensor outputs instantaneously via smartphone apps and should monitor at the scale of Irrigation scheduling (daily-weekly)

Installation

How long does installation take and who does installation?

The user installs the Arable Mark 2 and installation take about an hour for a new user.

Installation/Removal

Can this remain in place around planting, harvest activities?

In annual crops like processing tomato, installation and removal occur around planting and harvest processes. In perennial crops like almond or pistachio, the Mark 2 can remain in row during harvest operations, but should be stored removed and stored during non-irrigating winter months.

Maintenance

What types of in-season maintenance are required?

Cleaning the top of the Mark 2 sensor is important so it can stay charged (solar-powered). Gently wipe the dome with water and a clean rag periodically, especially in dusty areas or following spraying events.
