Resumen: Background and Aims The aim was to assess the amounts of macro- (N, P, K, Ca and Mg) and micro-elements (Fe, Mn, Cu and Zn) lost by peach trees (Prunus persica L. Batsch) in all the nutrient removal events (pruning, flower abscission, fruit thinning, fruit harvest and leaf fall), as well as those stored in the permanent structures of the tree (roots, trunk and main branches). Methods Three peach cultivars were used. The biomass and nutrient composition of materials lost by trees at the different events were measured during 3 years. The biomass and nutrient composition of permanent tree structures were also measured after full tree excavation. Results Winter pruning and leaf fall were the events where most nutrients were removed. Nutrient losses and total requirements are given as amounts of nutrients needed per tree and also as amounts necessary to produce a t of fresh fruit. Conclusions The allocation of all nutrients analyzed in the different plant parts was similar in different types of peach trees, with each element having a typical “fingerprint” allocation pattern. Peach tree materials removed at tree pruning and leaf fall include substantial amounts of nutrients that could be recycled to improve soil fertility and tree nutrition. Poorly known tree materials such as flowers and fruit stones contain measurable amounts of nutrients.
