Researchers from the University of Lleida, the Polytechnic University of Valencia, the University of Castilla-La Mancha and technicians from Natural Environment Engineering and AGRESTA have visited the experimental plots for structural diversification (action C4) and post-fire regeneration (action C5) of the Life AdaptAleppo project to install an experimental device.

The objective is to evaluate the effects of silvicultural treatments applied on the biological activity of the soil, measured through the decomposition rate of organic matter.

To do this, the teams have followed a standardized protocol that consists of burying bags of two different types of tea (rooibos and green tea) in the ground to dig them up after 60 days and evaluate the weight they have lost. This methodology is included in the international initiative “tea bag index” ( ), which gathers data from more than 500 similar devices around the world.

After the summer, the bags will be dug up, dried and weighed.

It is to be expected that silvicultural treatments have accelerated soil activity through greater insolation.
