MEASURING DECOMPOSITION USING SODA LIME DATA FORM 4: SUMMARY

Use this form to compile results from all of your soil samples. If your sample ID #s represent replicates of the same soil, then you can average the CO2 production rates. If your experiment involved using treatments, such as measurement of decomposition rates in soil containing worms vs. without worms, then you should take averages of any replicates within each treatment.
