Abstract

An artificial microcosm for the ectorhizosphere is described where a growth-limiting nutrient is supplied by diffusion at a predetermined rate from a cylindrical ultrafiltration membrane in the form of a hollow fibre. The artificial microcosm is thermodynamically open, reflecting the nature of soil, allowing tighter control of both growth-limiting nutrient and energy fluxes and it incorporates a leaching mechanism. To date the system has been shown to reach steady-state and the control parameters are currently under investigation.
