Beheer Beïnvloedt Relaties Tussen Bodemeigenschappen En Het Tulpenmicrobioom

Conventional agriculture relies on high inputs of chemical fertilisers and pesticides, leading to extensive damage to the soil. There has been a shift towards organic cultivation to ameliorate these negative effects. However, many knowledge gaps remain. We sampled soils and bulbs from tulip fields with conventional, organic and hybrid (i.e., combination between conventional and organic) management regimes to determine effects on abiotic and biotic soil properties, tulip bulb microbiomes/biota and network connectivity between them. We found that many biotic properties were driven by management and microbial community composition was determined by an interaction between soil texture and management. Specifically, conventional management created heterogeneous bacterial and homogenous fungal soil communities across soils types. Network analyses revealed more independent nodes of association in sand fields, with detrimental management techniques isolated from interactions with most soil (abiotic and biotic) and bulb biotic properties, while clay field networks showed the opposite. Our results indicate that conventional management can have a homogenizing effect on soil microbial communities, with potential impacts on soil function and buffering capacity to stress. Increased modularity between soil properties, management techniques and tulip bulb biota in sand fields could mean increased resistance to disturbance and stress.
