Some pulp or residue remains after coffee is prepared. Tropical forests can be born in open ground, that is, where the crop has been harvested. And for the sake of the coffee residue, that forest will grow very fast. The study was published in the journal Ecological Solutions and Evidence.
The researchers chose an innovative approach to research. The remains of 30 truckloads of coffee were dumped on a 35-40 meter land. Another piece of land of the same size was left behind. Rebecca Cole, a lead researcher at the University of Hawaii in the United States, says there’s been an incredible difference. In just two years, a small forest has sprung up on the land where the coffee was left. Needless to say, other lands, where nothing was planted, grew nothing but regional grass.
If 60% of the land where the coffee was planted was forested, only 20% of the land was planted where nothing was planted. And the land where the coffee is left is much taller than the other land. Researchers are surprised that this amazing thing happened in just two years.
Thus, if the land is left after harvesting, grazing is created there. Within a year or two, grass grows there. But the grass could no longer grow to remove the half-meter-high coffee residue. Once grass starts growing on the land, it is very difficult to create forest or jungle there. If there is no grass, the seeds of the forest can be floated by birds or other animals and in the air without any hindrance.
The researchers also found that phosphorus, nitrogen and carbon also increased in the land where coffee was left behind two years later. Soil samples were also tested before and after the coffee residue was removed. Tree species, their length, etc. have also been observed using drones.
