The nitrogen (N) balance was estimated in a very high density olive orchard in north- east of
Spain, in order to calculate the inputs and outputs of N related to tree response and soil
nitrogen availability. The calculate N inputs and outputs showed that N exported by yield and
pruning material were higher for fertilized plots than unfertilized ones, and no significant
differences were recorded for nitrogen mineralization between both treatments. N balance,
defined as the difference between inorganic N content in soil at the end and the beginning of
each year, was positive for both treatments but when vegetative growth and olive yield were
compared, fertilized plots showed higher values, So it is wrong noting that a positive N
balance in both case means that olive tree will provide a peak yield and vegetative growth but
it is an adaptation of the olive trees to different soil N availability conditions by equilibrating
their vegetative growth and fruit yield.
