Tea Bag Index: version adapted for spring measurements in Belgian winter cereals v2

The original Tea Bag Index (TBI) protocol was developed by Keuskamp et al. (2013). By burying tea bags, this method measures two variables related to the dynamics of labile organic matter in soil: (1) Decomposition rate (k), the rate at which the labile fraction of organic matter (tea) is mineralized in the soil, (2) Stabilization factor (S), the extent to which environmental conditions inhibit the decomposition of the labile fraction. The version presented here is adapted from the original protocol for use in Walloon winter cereal fields within experimental plots of one hectare. Modifications include an increased number of samples per plot and a more precisely defined burial procedure.
