Advancement in soil microcosm apparatus for biogeochemical research

Application of soil microcosms has largely improved our understanding in biogeochemical processes, because all major environmental factors can be independently controlled. Recent advancement to improve the performance of soil microcosm has been made. The modifications include using a different incubation vessel and cap, replacing a magnetic stirrer with an overhead stirrer, providing temperature control for the microcosm, using data logger for continuous measurements of redox potential (Eh), pH and temperature, and applying automatic gas analysis. The modifications can be made in any combination to suit an individual's needs and budget.
