Resumo(s)
Agricultural soil quality is an issue that has been widely debated in the literature in recent
decades. Three olive grove areas (one in Lisbon and the others in Santarém, Portugal) with different
management techniques (intensive and super-intensive) were selected. Nutrient concentrations
and enzyme activities of soils were determined, as well as the C and N of litter and pruning waste
(mulch) to estimate the influence of management techniques on the quality of olive grove soils and to
assess the extent to which they are affected by organic covers and different cultivation intensities.
Organic C and total N concentrations in soils of the intensive olive grove in Lisbon were the highest
when compared with those in the intensive and super-intensive olive groves soils of Santarém. The
concentrations of Ca, Mg, Na, and K were the main differences between the Lisbon olive groves and
the other two from Santarém. Phosphatase, cellulase, and urease activities were related to the Na,
extractable K, extractable P, Zn, Mn, organic C, and total N soil concentrations. Soil management and
agricultural practices are determining factors for these enzymatic activities of Santarém olive groves,
although climate conditions and soil properties play an important role in the soil enzymatic activities.
