Efficacia delle Fasce Tampone e della Gestione del Suolo per il Controllo dei Nitrati in Vigneto

Buffer strip use in vineyard could represent an environmental strategy for nitrate control of surface and deep water due to agricolture managment. Buffer strip determines a reduction of soil erosion and consequently can reduce nutritive and pollulant elements losses. With the aim to evaluate buffer strips and soil managment effectiveness on nitrate control in vineyard, a trial was carried out in a South-West part of Sicily characterized by an high nitrate losses sensitivity, an annual rainfall of about 516mm and an average temperature of 18°C. In a vineyard on about 7% slope and 90m lenght a 10 meter buffer strip was seeded using a Lolium perenne permanent meadow. Vineyard was managed both …
