The use of charcoal as a soil amendment on degraded soils in Guyana was the highlight when the National Agricultural Research and Extension Institute (NAREI) held its Open Day at Mon Repos, East Coast Demerara recently.
The project is being done in collaboration with the Inter-American Institute for Cooperation on Agriculture (IICA).
A number of Primary, Secondary and University students along with crop and livestock farmers and stakeholders within the bio-energy fraternity were invited to witness the demonstration of Giant King Grass plants grown in charcoal amended soil under shade house conditions in NAREI’s compound.
When this project is completed by March 2018, farmers on marginal and degraded soils will be trained to improve their soil quality using ground charcoal as a good agricultural practice.
NAREI’s Research Scientists, Mr. David Fredericks and Ms. Tracy Persaud are spearheading the project with assistance from Research Assistants Denisia Whyte and Jadason Bess. The team chose Giant King Grass as a test crop to explore its potential as a feed for livestock, a biomass source for bio-energy and bio-char for rehabilitation of marginal or degraded soil.
The soil material used was sourced from Kara Kara mining site, Linden. The first harvest was completed earlier this month, and the rationed re-growth for the second harvest is in progress.
This project was introduced to Guyana last year when IICA sponsored a training session on the ‘Management of Degraded Soils using Organic Matter in the Caribbean’, which was held in Jamaica. Persaud attended this training in which participants were expected to implement rehabilitation projects for degraded soils.
NAREI’s Chief Executive Officer, Dr. Oudho Homenauth told the invitees that the institute is promoting a green economy and to do that, soils are very important. “We are looking at Hinterland areas and Linden where there are marginal soils that are poor for agricultural production.”
