Abstract
A fertilizer subtractive trial was established in an olive grove, cv.
Galega, installed on a Calcaric Cambisol, in the Portuguese Region of Ribatejo.
During four years N, P, K and Mg were annually applied to the soil, as well as Fe, Mn, Zn, Cu, B and Mo applied by foliar spraying.
The macronutrient seasonal trend, both in trees with and without fertilization, was studied from full blossom to 310 days after.
Fertilization leads to a significant leaf-N increase both in bearing and non-bearing years as well as a leaf-K decrease in bearing ones.
In non bearing years the concentrations of leaf-N, P and K were higher along the season, whereas leaf-Ca and Mg seasonal trends were different in bearing years as compared with non-bearing.
