Decomposition study using tea bags

Comparing the decomposition of green tea as a fast -decomposing material with rooibos as a material, which is difficult to break down, allows for the calculation of the tea bag index. This provides information on the capability of the soil as a living organism to transform organic residues back into plant-available nutrients and make some contribution to the build-up of soil humus. This technique is easy to apply. Place the tea bag in the soil and take it out after three months to see how much is left. It is fascinating to discover the result of our hard working little helpers in the soil and how this work is giving nutrients to a new generation of plants.
