Carbon Mineralization in Agricultural Fields II

Overview

The purpose of this project is to test MultispeQ methods of determining soil biological activity. We are using a 5 minute protocol for both in situ measurements using closed chambers over the soil and ex situ measurements in canisters (where the soil is removed, weighed, and placed in a chamber).

Protocols

Soil Biological Activity 5 minutes

Measures CO2 concentration in a closed chamber over time. Often used to measure soil biological activity in samples of soil or compost either in the field or in the lab. The parameter of interest is the slope of the initial rise in mg C directly after closing the chamber. This protocol measures CO2 at 5 second intervals for ~5 minutes.
