Do soil microorganisms have a role in circular agriculture?

I am a scientist focused on problem solving and with a great passion for microbial services and symbiotic interactions. I aim at finding ways of harnessing microbes to improve quality of life while reducing our environmental footprint. I believe that team work is key to generate knowledge with impact that promotes a more sustainable agriculture and circular economy.

I am currently working on projects focused on assessing the impact of waste products as fertilizers for crops, thus contributing to circular agriculture. This involves addressing topics like:

  1. Soil suppressiveness. Could we help to better manage plant diseases and nutrient constraints that affect crops through the application of soil amendments? How? By developing an holistic research on soil disease suppressiveness which integrates different players (soil, roots and their microbiomes) and different expertise (chemistry, root physiology and microbial functional ecology).
  2. Transmission of antibiotics resistance. How to avoid human risks such as the transmission of human pathogens and antibiotics resistance? We are studying how antibiotics and pathogens are transmitted in the food production chain (waste product-soil-crop).


I studied biology and was trained as research assistant in molecular biology and genetics. Later I specialized in microbial ecology, plant physiology and biological control. During my PhD thesis I studied beneficial root traits that help plants to adapt to drought conditions via root signaling molecules and fungal symbionts. Currently I am a researcher in the Biointeractions and Plant Health group in Wageningen Research.

KB Microbiome program

In a circular economy, waste is used as a raw material for new products. Animal waste stream such as manure is produced at a rate of 70 million tons/year in the Netherlands only. Manure can be used as plant fertilizer and soil improver in agriculture and horticulture. However, there are risks associated with the reuse of waste. Most of this manure is spread (whether or not processed) on the land as fertilizer, and exists a frequent occurrence of antibiotic residues from livestock farming. Antibiotic residues can circulate via manure to soil and plants, and to pose a selection pressure on natural microbiological populations in the circular production chain. In addition there is a second risk and this relates to transmission of zoonotic (especially viral and bacterial) pathogens that can enter humans via oral ingestion through consumption of fresh vegetables and fruit. The aims of this KB project is 1) to map transmission routes of antibiotic resistance genes and pathogens important to humans via manure, soil and plants, 2) to study how alternative diets affect broilers gut microbiome, health and behaviour, and 3) how waste streams used as fertilizers affect soil microbiome and plant resilience.

KB Novel emerging pathogens

The aim of this project is to optimize the preparedness of Wageningen Bioveterinary Research (WBVR) to tackle emerging threats from infectious diseases in animal populations effectively and in a multidisciplinary manner (early warning, recognition, diagnostics, characterization, epidemiology, prevention and control).
