A pot for use with system for controlling soil moisture in a plurality of potted plants to perform water deficit experiments includes a body portion having an open top end and a bottom end, and a flange coupled to the body portion adjacent the top end. The flange is configured to engage a platform to hold the body portion within an opening of the platform. The pot also includes a fluid reservoir having a bottom portion located adjacent the bottom end of the body portion, a plurality of vertically extending fluid channels extending upwardly toward the top end of the body portion, a fill opening located at the bottom end of the body portion in communication with the bottom portion of the fluid reservoir, and a check valve coupled to the fill opening to permit fluid to be supplied to the fluid reservoir from the bottom end of the body portion through fill opening and the check valve.

Automated gravimetric screening platform system and method

A method for controlling soil moisture to perform water deficit experiments on a plurality of plants located in soil contained within a plurality of pots supported in a plurality of openings of a stationary platform includes lifting the plurality of pots with a plurality of load cell modules and weighing each of the plurality of pots with the load cell modules. The method also includes determining whether each pot needs to be watered based on the weight of the pot and the water deficit experiment, watering the pots through the load cell modules, if necessary, and lowering the plurality of load cell modules so that the plurality of pots are supported by the platform.

An automated gravimetric screening system and method controls soil moisture in a plurality of potted plants to perform water deficit experiments in a greenhouse using a stationary support platform and pot design that maintains the plants in a static location during the testing. By weighing and re-watering the pots from beneath the platform, the present system and method permits an upper gantry to capture high resolution images, temperature data, or other sensor data to quantify the plant stress level or plant canopy characteristics during the experiment.
