On 21 March, the team from the University of Valladolid traveled to study area B, in the small town of Congosta, in the municipality of Vidriales Ayoó Zamorano.

During this travel we took some samples of the soil and plants in several subplots which correspond to the different tests. 


  • First of all, with regard to the ground, earth is removed with an auger to a depth of 15-20 cm.
  • Secondly, the tests are conducted to calculate the biomass of the plot. Therefore, the soil was samples four times in the phenophase by throwing a ring of random m2 in each subplot and removing all plants (including root) within this ring. Furthermore, we weighed and measured the different parts of the plant in the laboratory and made an estimate of the total biomass present. Then we analyzed the carbon content of different organs to obtain accurate data of CO2 captured by the plant so far.

After being dried, the land was analyzed for total carbon content.

All test points on which the plants were sampled, as those which have been sampled at the georeferenced ground, were tested through a GPS solution based correction code and RTCM real-time corrections. With this format, the tests were accurate with an accuracy of below the meter in which test points are obtained from different samples and therefore enables them to return to the following stages.
