We have implemented a range of measures to provide shelter and a source of food for a variety of macrofauna (earthworms, hares, birds, butterflies, tree frogs, etc.) and microfauna (bacteria and fungi). Such is the case with inter-row seedlings, which are mixtures of rye, vetch and red clover, but also oats, alfalfa, sainfoin, red clover and trefoil.
The seedlings return nutrients to the vine. They limit erosion and soil compaction, and improve soil porosity and bearing capacity. By providing shelter and a source of food, they encourage macrofauna (earthworms) and microfauna (bacteria, fungi).
