Rhizobox Systems for Root, Rhizosphere and Soil Monitoring

Try our rhizobox configurator to set the target dimensions of rhizoboxes / rhizonboxes and calculate the effects on rooting space and appriximate the amount of soil required.

Rhizobox / root box systems are used to i) separate rhizosphere soil from bulk soil, ii) are a feasible way to study different aspects of soil - soil pore water - root interactions, iii) to measure root growth, turnover and spatial distribution (and a large range of other root traits relevant to characterize root sytems in phenotyping approaches), and iv) to sample defined root types (e.g. age classes, orders) or soil areas (rhizosphere / bulk soil).

Recenty, Yee and colleagues (2021) provided a great overview on representative rhizobox designs, showcasing the manifold rhizobox configuration options for specific research questions (see Figure). (Subpannel A) "Classical" Rhizotron/Rhizobox set up, (B) Rhizobox with side-compartment, (C) vertical and (D) horizontal root mat chambers, root boxes with (E) mycorrhizal compartments (e.g. separated by 50 µm mesh and/or air gaps), and (F,G) split-root or -box designs (see "Splitbox-design") with complete or semi-permeable compartments. See Yee et al. (2021) for details. Please consider the target plant size when selecting a certain rhizobox size, and the potential effect of root illumination on your results. The integration of RRPs' (Micro-)Rhizons and RhizonIrrigators into the established VSI Rhizobox systems ("Rhizonboxes") creates advanced opportunities for soil water sampling and manipulation in root boxes. Rhizobox racks for angled placement and top-up chambers for gas flux measurements or isotope labelling complement our root box portfolio. For studies under flooded soil conditions, we are currently developing hydroponic rootboxes. Roots on rhizobox images can be analysed with software programs (see below), however, rhizoboxes are also an educative way to illustrate root (and shoot growth) to younger audiences. Ultra large rhizoboxes (Rhizotrons) have been build to exemplify the importance of root systems for plant growth and yield to stakeholders and the general population in educative exhibits at company facilities or natural science museums.
