Smart soils to observe hidden rhizosphere processes

Le résumé fourni par la source

Summary Agriculture must reduce green-house gas emission and pollution, produce safer and healthier food, closer to home, reducing waste whilst delivering more diverse diets to a growing world population. Soils could enable this transformation, but unfortunately, they have a hugely complex and opaque structure and studies of its myriad of mechanisms are difficult. Here, the fabrication of smart soils for the screening of below-ground bio-processes is demonstrated. Particles were generated from fluoropolymer waste with functionalisation converting them into sensors able to report on key chemical dynamics. Tailored functionalization was obtained by radical terpolymerisation to improve growth conditions and sensing capabilities. The study demonstrates the potential for the development of accelerated genetic or agrochemical screens and could pave the way for improved models for rhizosphere dynamics.
