Biographical details

Feike is a biogeochemist with interest in plant-microbial interactions affecting carbon and nutrient cycling, particularly in relation to global climate change. Research in our group is focused on rhizosphere priming, the phenomenon whereby plant root activity can accelerate (or decelerate) microbial activity and soil organic matter decomposition. Within our group we are examining how environmental factors control rhizosphere priming and what the consequences are for nutrient cycling and plant growth.


Despite their importance, plant-microbial interactions on carbon and nutrient cycling remain poorly described in ecosystem models, largely because these complex interactions are still not fully understood. Many questions about plant-microbial interactions remain unanswered but are important for a better understanding of carbon and nutrient cycling in a changing environment. For instance:


• How do plant-microbial interactions affecting carbon and nutrient dynamics vary with belowground resource availability (nitrogen, phosphorus, water)?
• How do plant-microbial interactions benefit plant growth?
• To what extent are plant-microbial interactions controlled by C:N:P stoichiometry constraints on plant and microbial growth?


To address these questions, we use field, greenhouse, and laboratory experiments, often in combination with stable isotope techniques and other state-of-the-art methods. We also develop simple dynamic models and use ecosystem simulation models to better understand the importance of plant-microbial interactions for carbon and nutrient cycling in different types of ecosystems affected by global change.

Research interests

Our group is currently working on the following projects:


Drought effects on soil carbon and nutrient cycling mediated by rhizosphere processes. Drought effects on soil carbon storage and nutrient cycling are examined in tree, grassland and wheat cropping systems using innovative carbon and nitrogen isotope labelling techniques. This project focuses on processes that occur at the interface between plant roots and soil that are vital for soil carbon storage and climate feedbacks, and sustainability of natural and agro-ecosystems. We are developing and modifying process-based and dynamic models to incorporate root-soil interactions and to predict long-term drought effects on soil carbon storage, nutrient loss, and plant productivity.


Exploring beneficial GxExM interactions for crop yield: effects on soil health. The effects of wheat genotypes (G), environment (E, temperature and water stress), and management (M, crop rotation, fertilizer, and tillage) on soil health and key processes of carbon and nitrogen turnover are studied. Plant traits that affect belowground processes are seldom considered within breeding programs. However, better knowledge about belowground plant traits is desperately needed for sustainable agriculture. One of the aims of this project is to link belowground traits of wheat genotypes to soil nutrient dynamics and to microbial community structure responsible for supplying nitrogen and phosphorus to plants.

Impacts of biochar on soil carbon decomposition and stability. In this project the stability of biochar and native soil carbon is investigated. Biochar is charcoal produced by pyrolysis of biomass (e.g., from crop residues, green waste, chicken manure, wood chippings). Biochar amendments to soil can improve soil carbon thereby mitigating global warming. However, little is known how biochar interacts with plant root exudation and microbes responsible for soil organic matter decomposition. In this project we are investigating the interactive effects of biochar and plant rhizodeposition on biochar and native soil carbon decomposition in cropping and intensive pasture systems.
