Synchronizing the availability of N in the rhizosphere with its uptake pattern by the trees
throughout the vegetative cycle enhances the efficiency of its use. This study aimed to: i)
quantify the N use efficiency in the non-bearing pear trees, fertigated with 15 N and ii)
identify the pear tree N storage organs and access the distribution of N derived from the
fertilizer (NDFF) in the organs. One-year old pear trees (Pyrus communis cv. Rocha on
quince BA29 rootstock) planted in a loamy sand soil at 4 mx 1.5 m spacing, were supplied …
