Macro and micronutrient demand in peach trees

Abstract

The aim of this work is to attempt to estimate the nutrient budgets in peach trees. The real nutrient demand was estimated by measuring losses due to output of nutrients at different events, including wood pruning, flower loss, fruit thinning, fruit harvest and leaf fall. An estimation of the amounts of nutrients immobilized in wood and roots was also carried out. Samples from two different peach orchards (Prunus persica L. Batsch) grown on calcareous soils in the Northeast of Spain were used for this estimation.
