Abstract

Essential mineral nutrients are key elements for the development and production of grapevines. Under natural conditions most nutrients have a lithogenic origin, however, in agroecosystems their contents and distribution can be greatly altered by anthropogenic additions. To assess the origin and contribution of lithogenic and anthropogenic nutrient sources, we studied the rock-soil-water-fruit interfase in four vineyards of Central Chile located in the sites of Casablanca, San Antonio, Santa Cruz and San Javier, which are characterized by contrasting geological, geomorphological, and mesoclimatic conditions as well as the magnitude of anthropogenic influence.
