Forensic expert

I am a forensic expert, registered with the NRGD (Netherlands Register of Court Experts, www.lrgd.nl, registration number D0571).

Soil problems

Sometimes the solution is obvious, but often more in-depth research into the cause and its control is required.

Unknown cause

Is your crop growing poorly and you don’t know why? I am happy to think along with you about how we can reach a solution. I know which analyses and laboratories can help you further, and I can interpret the results well. I also assist plant researchers dealing with poorly growing plants.

Ecology of plant pathogens

For all plant pathogens I provide you with information on the available knowledge regarding control, conditions needed for inactivation (for example during composting), dispersal, and related topics.

Killing of pathogens, human pathogens, nematodes and weeds

In agriculture and horticulture, composting is a widely used method to kill all kinds of unwanted organisms such as pathogens (incl. human pathogens), nematodes and weeds, thanks to the high temperatures involved. However, other methods are also available, depending on the medium and the quantity that needs to be treated. Think of steaming, anaerobic soil disinfestation, or flooding.

Biostimulants

Few pesticides are available for application in soil — perhaps that is precisely why there are even more alternative products, which are often called biostimulants. I separate sense from nonsense.

Identification of rust fungi

I identify all rust diseases. See the rust page.

Project proposals

Would you like to add soil science or plant pathology aspects to your project proposal? I can provide ideas. I have written numerous successful project proposals for universities as well as for businesses. I can also give your proposal a more scientific or, conversely, a more applied focus.

Lectures

I gladly give lectures on soil life, soil improvement, and the ecology of plant pathogens.
