Het handboek 'Impact van waterkwaliteit en irrigatiebeheer in de biologische glastuinbouw' is een unieke bron van informatie voor kwekers, onderzoekers, studenten, docenten, consultants en leveranciers die betrokken zijn bij de biologische beschutte teelt. Deze publicatie kan helpen bij het ontwikkelen en implementeren van meer duurzame strategieën in verband met irrigatie in de biologische glastuinbouw.

Zeven experts uit verschillende regio's en achtergronden werkten samen aan dit onderwerp. Deze experts   onderzochten in detail het waterbeheer toegepast in diverse beschermde teeltsystemen in Europa en Noord-Amerika aan de hand van:

  • de behoefte aan water
  • de watervoorraad
  • de vraag naar water van het gewas
  • de irrigatietechnologie
  • het irrigatiemanagement
  • de wisselwerking tussen gewasontwikkeling, -kwaliteit en irrigatie
  • de duurzaamheidsaspecten.
