Matís, in collaboration with the Icelandic Ocean Cluster, has been conducting an exciting research project investigating the effects of biochar on soil and plant growth. The project was funded by the Icelandic Student Innovation Fund and is also part of a larger research project that explores the potential of using biochar as a soil improver; the Soil Improver Biomaterials project , which is led by the Icelandic Ocean Cluster.
The project was carried out by student, Ásdís Ögla Sigurðardóttir, who supervised the daily implementation of the experiment this summer. Amongst other things, she monitored the growth of the plants, watered them, kept track of the data, and will submit the results in a final report in the coming weeks. She commented, "During my studies in food science, I became interested in sustainability and how research contributes to the development of sustainability and innovation in food production. When I learned about the project Lífkol: a bridge between aquaculture and agriculture, I saw an ideal opportunity to connect these areas of interest."
In the experiment, which took place on the roof of the Matís plant at Vínlandsleið, cabbage plants were grown in different mixtures of soil and biochar. Among other things, biochar made from fish farm sludge was used. The goal was to see if this unconventional biochar has a comparable or even better effect than traditional biochar made from wood waste.
"I was surprised by how variable the effects can be depending on biochar produced from different raw materials, there seems to be a clear difference between biochar from fish farm manure from saltwater on the one hand and freshwater on the other. It was also interesting to see the effects of different concentrations, i.e. the proportion of biochar in the soil and how it affected plant growth," says Ásdís.
This project represents an important step towards sustainable utilization of organic by-products and better soil utilization. The results could have a positive impact on waste streams and agriculture in the future and, perhaps, use of biochar from aquaculture manure may be part of the solution.
Student grants, like this one from the Student Innovation Fund, are crucial for young people who want to gain experience in real-world research projects and contribute to innovation and sustainability. Matís regularly welcomes students to participate in a variety of projects.
"The experience has been very educational and enjoyable. I got to work independently, participate in decisions and receive constructive criticism. I learned a lot about all aspects of research work, from experimental design to data analysis, and strengthened my self-confidence to work within the research field," Ásdís concludes.
The results of the project will be published in a report later this fall.
