Greenlandic rock-flour - New research shows that Greenlandic rock-flour significantly enhances plant growth
08.09.2021 - 09.09.2021
Every year, billions of tons of rock-flour is washed out with melt water from the glaciers of Greenland. There is a near infinite amounts of the material, and its high content of mineral nutrients can be part of the solution to the climate crisis and bio-diversities grand challenges. Rock-flour has the potential to improve food security for all of us.
Professor Minik Rosing has over the past three years - in collaboration with the Novo Nordisk Foundation - investigated the properties of the Greenlandic rock-flour and carried out growth experiments in Ghana and Denmark. These experiments show that crop productivity can be improved significantly by the administration of rock-flour to the soil, and that the positive effect is sustained through several growth seasons.
Minik Rosing states: "We have been positively surprised by the high increase in crop yield we see when we fertilize with Greenlandic rock-flour on the experimental plots in Ghana and Denmark. Actually, the effect increases year by year at least into the third growth season in the Ghana-plots where we have grown maize. What initially started out as an idea has now proven to be reality: Greenlandic rock-flour works!"
There is so much of this ultra fine-grained rock-flour in one lake by the Nuuk Fjord that it could improve the nutritional value of all agricultural lands south of Sahara in Africa.
Debate in Katuaq, Wedensday 8 September at 16.30 - 18.00
Minik Rosing wishes that the results of his rock-flour research benefits Greenland and emphasizes the importance of making them available to Greenlandic stakeholders and operators as a first step.
Ilisimatusarfik has therefore decided to make this possible in collaboration with Minik's home-institution GLOBE-Institutet at the University of Copenhagen.
In Katuaq on Wedensday 8 September at 16.30 - 18.00, Minik Rosing presents the subject and results and takes the floor in the ensuing debate under the chairmanship of rector Gitte Adler Reimer. Naalakkersuisoq Naaja Nathanielsen introduces Minik Rosings presentation with a focus on the regulations and opportunities that are of interest for such projects, and Naalakkersuisoq Kalistat Lund introduces with views on agricultural development and self-sufficiency in Greenland.
Workshop at Ilisimatusarfik, Thursday 9 September at 09.30 - 12.00
New research results show that the fertilizing effect of Greenlandic rock-flour on a number of crops is much greater than expected - and on that background Minik Rosing and his team will continue collaboration with the Novo Nordisk Foundation the coming years to research the potential in greater detail. At the same time, there is a need to discuss how to operationalize the exploitation of Greenlandic rock-flour in Greenland.
On a workshop for potential Greenlandic operators at Ilisimatusarfik, Thursday 9 September at 09.30 - 12.00, Minik Rosing will offer his insights and enter into a dialogue with interested people on potentials and barriers.
With kind regards;
Rector Gitte Adler Reimer & head of institute Anna Kleist Egede
