Forest recovery using coffee waste!

New York: COFFEE pulp, a waste product of coffee production, could be used to speed up tropical forest recovery on post agricultural land, suggests a new study.
In the study published in the journal 'Ecological Solutions and Evidence', the team spread 30 dump truck loads of coffee pulp on a 35-40m area of degraded land and marked out a similar sized area without coffee pulp as a control.
"The results were dramatic", said lead researcher Rebecca Cole from the University of Hawai'i in the US.
"The area treated with a thick layer of coffee pulp turned into a small forest in only two years while the control plot remained dominated by non-native pasture grasses," Cole added.
After only two years, the coffee pulp treated area had 80 per cent canopy cover compared to 20 per cent in the control area. The canopy in the coffee pulp area was also four times taller than that of the control area.
The addition of the half metre thick layer of coffee pulp eliminated the invasive pasture grasses which dominated the land.
