Plants are cultivated in soil-filled custom-made rhizotrons positioned at a 45 degree angle.

Screen Root

Screen Root

The automated system (rhizotron-to-sensor) is suited for quantitative measurement of root architecture parameters in 2D and shoot biomass evaluation (up to 80 cm height) via projected shoot area.

Typical throughput is 72 rhizotrons/day.

Assays include the evaluation of root and shoot responses to different water, nutrient (N, P) and soil compaction regimes.
