Agriculture in general acts as a carbon sink during its life cycle, photosynthesis. Through this function, plants absorb CO2. This sequestration of CO2 is the difference between that absorbed during photosynthesis and that emitted by the atmosphere during respiration. This difference is converted into biomass, so if growth is high, natural vegetation and agricultural crops become carbon sinks. Agriculture is an effective mechanism to mitigate the increase in atmospheric CO2, thanks to its great fixation.
The research carried out by CSIC Research Professor, Ms Micaela Carvajal on the absorption of CO2 by the most representative crops of the Region of Murcia, shows us very encouraging results for our sustainable agriculture, especially that of our crop, the lemon Tree. These results, in addition to being very different with the rest of the citrus fruits (orange and mandarin), are also different with the rest of the crops, the lemon, due to its greater biomass, is the crop with the greatest capacity for fixing CO2. In this work, a total of 8.3 t / ha and carbon year are set (106,933 g CO2 / tree).
As a conclusion to this study, we depend on plants to counteract the greenhouse effect.
In the case of one of our farms of 500 ha of surface, 210 of these are lemon trees, with which we set 1,680 t of C / ha and year, or what is the same, our 67,000 trees set 7.164 t of CO2 per year, although the maintenance of the adventitious plant cover in other farms that we grow under an ecological regime, the resulting value is higher.
The rest of the farm, 290 ha are wild, we do not know with certainty how much CO2 our lung, the great pine forest, but surely a lot, our environmental policy and the sustainability of our operation is assured.
Such is our commitment to the environment and after two years of long drought, the pines have suffered and this past summer the attack of the pine processionary was strong, so we have proposed working through non-chemical methods to reduce these damages in the pines.
As seen in the image, we have placed trap traps of the adult of the pine processionary (Thaumetopoea pityocampa), through its specific pheromone of attraction we managed to reduce the population of this pest.
