Bodemkwaliteit in de Bollenstreek: invloed op ziektedruk & rendement: Een verslag over de relatie van bodemkwaliteit tot ziektedruk en de benodigde maatregelen tot een duurzaam en rendabel bodembeheer

Sustainable soil management is receiving more and more attention, because chemical crop protection is becoming increasingly limited by stricter regulations. A healthy soil reduces the risk of diseases and pests because the crop has more chance to grow optimally. Increasing resilience can be achieved in various ways, but only works well if the conditions for abiotic and biotic factors are optimal. It is difficult to estimate whether a more resilient soil can replace the current chemical approach. Patience is required to increase crop yields through improved soil quality. The return can be higher due to an increase in revenue or a reduction in costs. However, measures also involve costs and risks. The exact feasibility is therefore difficult to calculate. Flower bulb cultivation is capital intensive. As a result, the sector is generally risk-averse, but investments in soil quality and future-proof cultivation can pay off more quickly. Knowledge gaps are mainly specific to bulb cultivation on dune-sand soils: research into reduced tillage and its effects on the organic matter balance is impossible to find.
