Storage and remobilisation of nitrogen by pear (Pyrus communis L.) trees as affected by timing of N supply
M Quartieri, P Millard, M Tagliavini - European Journal of Agronomy, 2002 - Elsevier
Orchard nitrogen (N) management should aim at reconciling productivity, fruit quality and
environmental concerns. Fertilisation strategies should, therefore, maximise the efficiency of
N fertilisers, including the choice of the optimal timing of N supply. In the present study, with
the aid of labelled [Ca (15NO3) 2] fertiliser, we assessed:(1) the uptake;(2) the partitioning of
nitrogen in 1 year; and (3) its remobilisation the following year, as affected by the timing of N
supply. Two-year old Abbé Fetel trees on quince C were grown in pots filled with sand and …
