On the diversity of nematode antagonists in an agricultural soil, and their steerability by root-knot nematode density and cover crops

Sara Giulia Cazzaniga, Philippe Belliard, Joris J.M. van Steenbrugge, Sven van den Elsen et autres

Plant-parasitic nematodes are harmful pathogens for many agricultural crops. Within this category, root-knot nematodes (RKN, Meloidogyne spp.) are worldwide regarded as the most impactful because of their wide geographical distribution and their polyphagous nature. Host plant resistances against RKN have been successfully …

Cover crop mixtures do not assemble markedly distinct soil microbiotas as compared to monocultures in a multilocation field experiment

Jose G. Maciá‐Vicente, Sara Cazzaniga, Marie Duhamel, Luc van den Beld et autres

Cover crops are used in cropping systems to enhance ecosystem services, such as soil resilience to erosion or microbial activity. Different cover crops are selected to steer specific processes, but whether cover crop mixtures have an added value over monocultures remains debated. …

Effects of several long-term soil health treatments on populations of Pratylenchus penetrans and the soil microbial community

E.H. Nijhuis, Viola Kurm, Johnny H. M. Visser, G.W. Korthals et autres

Abstract Soil suppressiveness can reduce the damage by plant parasitic nematodes (PPN) in agricultural soils and is conveyed by the activity of soil microorganisms. While natural suppressiveness has been reported, it is still poorly understood if soil suppressiveness can be elicited by …
