Om Louise C. Andresen


The BECC actiongroup 'Nutrient weathering from Rocks' workshop took place at ‘Geovetarcentrum’, University of Gothenburg, 10th - 11th October 2016. We bridge the concepts of long-term (geological) and short-term (ecosystem) N and P dynamics. Understanding the production and consumption of available nutrients is paramount for predicting ecosystem responses to climate change factors.

How N is imbedded and analyzed in minerals in the rocks, how stable isotopes (15N) can be a delicate tool for investigating the source and transfer of mineral nitrogen between the rock and the ecosystem, how modelling of phosphor released by weathering and nitrogen mineralization can be approached and integrated further; will be key points.

My research:

Soil nutrient dynamics strongly control the productivity and stability of terrestrial ecosystems and determine potential ecosystem responses to global change. New insight into the dynamics of nutrients in the soil - plant continuum is needed in order to achieve a more complete understanding of sources, sinks and retention of essential nutrients in terrestrial ecosystems. The role of organic nitrogen (N), non-biological nitrous oxide (N2O) emission, and release of inorganic nitrogen (IN) and phosphor (IP) from rocks are generally under-rated processes. In natural ecosystems, soil organic matter (SOM) fuels the recycling of nutrients; as microbes decompose SOM, they produce monomeric organic (e.g. AAs) and inorganic nutrients, ready for plant uptake. The focus ofmy research proposal is on the effects of acidification and elevated atmospheric CO2 upon: a) depolymerization and N mineralization rates; b) adsorption and desorption of nutrients from soil minerals and SOM; c) nutrient input to the soil - plant system directly from rocks; and d) loss of N from the ecosystem as N2O via chemical-denitrification.
