The work aimed at investigating the impact of various good quality soils of on vineyard productivity. Manure matured with a fast and controlled process and compost obtained from digestate of an organic fraction of municipal solid waste (OFMSW) were applied one time on a grapevine row, in two CAVIT vineyards. A physico-chemical characterization of the soils was carried out and biological quality indices QBS-ar (Arthropodological Biocenosis) were calculated. The vegeto-productive monitoring was performed by foliar nutrients analysis and measuring NDVI and SPAD indices. The organic source had a significant fertilizing effect, especially manure, which determined a nutrient increase in soil (P, K and Mg), a rise in photosynthetically active biomass, available nitrogen and potassium in plants. The effects on the biological community of soils and musts quality were negligible. The use of soil improvers could be an efficient strategy for the nutrition of not vigorous vineyards, which do not require high nitrogen inputs.

Backyard composting as a supplement to centralized plant composting is increasingly being accepted in many parts of northern Italy. Many people in small rural areas, residential districts and municipalities surrounding large cities such as Bergamo, Milan and Padua are recycling organic materials on their own initiative. They have been helped and encouraged by town governments which are almost exclusively promoting backyard composting programs through funding for the equipment or by discounting the municipal refuse tax on interested families by 10%-30%.
