Thirty years of professional research on soilless cultivation in the greenhouse horticultural industry with papers, scientific articles and patents on growing media and irrigation technology. Present focus on innovation with (conglomerates of) private companies for reciruculation of nutrients (ion specific control); resilient growing (enhancing functional groups); circular fertilisers (including organic fertilisers) and circular growing media. Specialties: Rooting media quality measurements, method development, propagation, irrigation and fertigation strategies.
