We describe a protocol to sample, preserve, and section intact roots and the surrounding rhizosphere soil from wetland environments using rice (Oryza sativa L.) as a model species. Once preserved, the sample can be analyzed using elemental imaging techniques, such as synchrotron X-ray fluorescence (XRF) chemical speciation imaging.

Excavation of plant roots from the field as well as processing of samples into endosphere, rhizosphere, and soil are described in detail, including DNA extraction and data analysis methods. This paper is designed to enable other laboratories to use these techniques for the study of soil, endosphere, and rhizosphere microbiomes.
FAQs
Root-driven reactions can create sharp local changes in nutrients, ions, metabolites, minerals, and microbial activity that disappear when soil is mixed into a bulk sample. Rhizosphere imaging preserves these gradients, allowing researchers to connect the location of a chemical transformation with nearby root processes and to distinguish localized effects from average soil conditions.
Optical methods can visualize relevant structures or activity, while spectroscopic and other spatially resolved chemical methods characterize the composition and distribution of substances near roots. Combining these approaches can relate visible patterns to chemical gradients, mineral changes, metabolites, or microbial activity, giving a more chemically informative picture than relying on a single measurement type.
Controlled moisture and nutrient conditions help researchers interpret whether observed chemical patterns arise from root interactions or from changing experimental conditions. These variables influence the local distribution of nutrients, ions, metabolites, and minerals. Maintaining defined conditions therefore improves comparisons among samples and supports clearer links between spatial chemistry and root uptake or nutrient cycling.
A study generally establishes controlled moisture and nutrient conditions, examines the root–soil region with an appropriate optical, spectroscopic, or spatially resolved chemical method, and maps the resulting distributions. Researchers then compare local patterns with root position and relevant chemical processes. This workflow converts spatial measurements into evidence about reactions, transport, and biological interactions near roots.
The approach is valuable when the research question concerns localized chemistry that bulk sampling may average away. It can examine root-associated nutrient uptake, transformations involved in nutrient cycling, contaminant mobility, mineral distributions, and plant–microbe interactions. The resulting spatial information is especially useful for explaining how small-scale reactions influence broader soil fertility or environmental behavior.
By showing where nutrients, ions, metabolites, minerals, or microbial activity concentrate near roots, the measurements can reveal chemical conditions associated with root uptake and nutrient availability. That information supports improved crop management and helps evaluate rhizosphere-based remediation strategies. It also contributes to environmental monitoring by showing how contaminants may behave in root-influenced soil zones.
