Agriculture research
In the Agricultural research section, we aim to understand the mechanisms behind the relationship between rock flour application and crop response. This knowledge will help optimize the usage of rock flour for agricultural purposes. We also seek to determine the optimal application rates and repetition strategies for different soil types, crops, and climates. Additionally, we focus on quantifying the CO₂ uptake resulting from the dissolution of rock flour, ensuring its eligibility for carbon credits.
Though our research is focused on Greenlandic glacial rock flour, many of our findings will have relevance for enhanced weathering of other silicate minerals in agricultural settings as well. Our key objectives include:
- Understanding the Mechanisms: We aim to uncover the underlying mechanisms that govern the relationship between the application rate of GRF and the response of selected crops. This knowledge will provide insights into optimizing GRF usage for agricultural purposes.
- Optimal Application Strategies: We seek to determine the optimal rates of application and repetition for GRF across various soil types, crops, and climates. This research will help guide the effective implementation of GRF as a sustainable solution.
- Quantifying CO2 Uptake: An essential aspect of our investigation is quantifying the rate of CO2 uptake resulting from the dissolution of GRF. We strive to develop robust methodologies to accurately measure and assess this process, ensuring its eligibility for carbon credits.
