Advancement In Soil Microcosm Apparatus for Biogeochemical Research.

Application of soil microcosm 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, and application of data logging for continuous measurements of redox potential (Eh), pH and temperature, and of automatic gas analysis. The modifications can be made by any combinations to suit individual’s needs and budget.
