Última Nitrogen balances in Dutch organic greenhouse production Organic Eprints Cuijpers, Ir. W.J.M.; van der Burgt, Ir. G.J.H.M.; Voogt, Dr. W.. The organic greenhouse production in the Netherlands is limited with regard to the number of growers, but plays an important role in EU organic greenhouse production. In the high-technology greenhouses a high production level is realized but nitrogen balances of this production system have been questioned. In order to document and improve the nitrogen balance, the production of seven greenhouses was monitored and soils were repeatedly analysed. The model “Bemestingsrichtlijn biologische kasteelten” (Fertilization Guide Organic Greenhouse Production) has been developed to simulate nitrogen availability and to fine-tune manure applications to crop demand. In the course of four years the overall nitrogen surpluses decreased sharply, but due to the...
