Tea bag index - citizen science

Citizen science

Date: 04/05/16 to 01/02/17

The European Soil Data Centre invites students to participate in a global citizen science project: Tea Bag Index

The objective of the Tea Bag Index is to create a global soil map of tea bag decomposition.

The Tea Bag Index measures decay of plant material by using two types of tea bags (green and rooibos) as standard plant. Tea bags are placed in the soil and weight loss is determined after three months. As the tea types are composed of different material, their decomposition is indicative for a two phased decomposition model, with a fast initial phase and a slower second phase when weight loss levels off.
