Under-sowing of green manures in organic vegetable crops
Groen-te-len - Groenbemesters onder biologische groenteteelten
Kontext
Good soil fertility is very important in organic farming. Green manure crops have a steering role in soil-forming processes but are difficult to incorporate in an intensive vegetable cultivation plan. Under-sowing of green manures in cereals (mainly white clover) and maize (grass and/or clover) is already common practice. However, this practice is still hardly applied in vegetable cultivation. Insights from regenerative agriculture that prioritises the use of green manures (crop diversity, soil cover, living roots (and root exudates)) gave CSA growers the idea for this operational group.
Activities
Through a combination of on-farm trials by the participating farms and some field trials at the research organisation, participatory research will explore which green manures can lead to a successful approach under which conditions in which vegetables so that the soil has maximum and diverse coverage with minimal impact on crop development and yield. Under-sowing of green manures in vegetable crops and the management of paths covered by crops also give specific mechanisation challenges. The operational group is looking for creative solutions that fit within a small-scale vegetable farm.
Activities
Door een combinatie van on farm proeven door de deelnemende praktijkbedrijven en enkele praktijkproeven op Inagro zal er in participatief onderzoek nagegaan worden welke groenbemesters onder welke omstandigheden in welke groenten tot een succesvolle aanpak kunnen leiden zodat de bodem maximaal en divers bedekt is met een minimale impact op de gewasontwikkeling en opbrengst. Onderzaai van groenbemesters in groenten en het beheer van groene paden brengen ook specifieke uitdagingen inzake mechanisatie met zich mee. De operationele groep zoekt ook hiervoor naar creatieve oplossingen die passen binnen de bedrijfsvoering van een kleinschalig groentebedrijf.

1 Practice Abstracts
Root exudates provide nutrients for microorganisms and shift the chemical and physical characteristics of the soil. Diverse vegetation (crops, green manures,...) is important. This is the approach of regenerative agriculture. Two innovative and participatory development paths are being developed: under-sowing of green manures in vegetable crops and covered paths/tractor tracks. The objective is to investigate which green manures are best applied under which conditions and in which vegetables so that the soil has maximum and diverse coverage with minimum impact on crop development and yield.
Possibly small-scale organic horticultural farms, with an intensive but diverse cropping plan, have more degrees of freedom for this than a larger-scale farm.
Planten voeden via hun wortelexudaten in belangrijke mate de bodem. Een diverse begroeiing (gewassen, groenbemesters,…) is daarom belangrijk. Dit is de insteek van regeneratieve landbouw. Er worden twee innovatieve en participatieve ontwikkelingstrajecten ontwikkeld: onderzaai van groenbemesters in groenten en het groen houden van de paden/trekkersporen. De doelstelling is om te onderzoeken welke groenbemesters onder welke omstandigheden en in welke groenten het best worden toegepast zodat de bodem maximaal en divers bedekt is met een minimale impact op de gewasontwikkeling en opbrengst.
Mogelijk hebben kleinschalige biologische tuinbouwbedrijven, met een intensief, maar divers teeltplan, hiervoor meer vrijheidsgraden dan een grootschaliger bedrijf.
