dc.description.abstractEnAchieving the sustainability of modern agriculture will require, among other actions, an improvement of the soil and its associated microbiota. One way to achieve this is through the inoculation with beneficial soil microbial communities. In this study, we used solid-phase fermentations to produce 25 distinct microbial inoculants based on complex communities obtained from the rhizosphere of 23 European vineyards. For this purpose, we mixed 0.1 g of donor rhizosphere soil and 25 g of ground and sterilized growing substrate composed of winemaking byproducts in 15-cm Petri dishes. Aerobic fermentations were carried out for a period of 56 days and the activity of microbial enzymes linked to the biogeochemical cycling of carbon, nitrogen, phosphorus, and sulfur was evaluated every two weeks. We then carried out a common garden experiment where the inoculants were tested in pots containing vineyard soil and planted with Tempranillo vines. During the fermentation, the enzyme activity of the inoculants evolved from no activity to high-activity values. Carbon- and phosphorus-linked enzymes tended to show higher activity after 14 days of incubation and then decreased or remained constant, while nitrogen-linked enzymes tended to show their highest values after 28 days of incubation. Despite these general patterns, inoculants developed from different rhizosphere communities followed different trajectories in terms of activity. In addition, we observed significant relationships between the enzyme activity of donor rhizosphere soils and the enzyme activity of inoculants, especially after 28 days of incubation. We also found a significant relationship between the enzyme activity of the inoculants and the enzyme activity measured in the soil of pots containing vines. Our results suggest the possibility of predicting the metabolic potential of the inoculants from the metabolic potential of their donor soil sample, as well as the possibility of transferring these metabolic capabilities to soils, with likely applications for the regeneration of the functioning of vineyards.
