Pig fertilizer from bioreactor in cucumber

Together with Wageningen University & Research, Van der Knaap Groep has conducted a test in which they have made use of two different types of mineral nutrients. Karel de Bruijn: "We look at the difference between mineral nutrients and mineral nutrients in which calcium and potassium nitrate is made of pig fertilizer using our bioreactor.

Circular fertilizer
The nitrogen from pig fertilizer will be mineralized and converted to high-quality fertilizer suitable for professional horticulture. Karel: "The bioreactor, which we know from organic nutrients, is again the key to success. There are a few more proceeding steps and the process is more extensive, but it does work very well."

Nitrogen problems
This manner of working contributes to a solution for nitrogen problems. Karel explains the process: "Because we make the products suitable for the professional horticulture, we help livestock farmers to resolve part of the fertilizer problems. Two industries are brought together."

The test has been concluded and the WUR is now analyzing the results. At the end of January, the report will be published and the exact results announced.
