A Comparative Analysis of Soil Loss Tolerance and Productivity of the Olive Groves in the Protected Designation of Origin (PDO) Areas Norte Alentejano (Portugal) and Estepa (Andalusia, Spain)

Olive groves are Mediterranean systems that occupy more than 2.5 M ha in Spain and 0.352 Portugal. Assuming the differences between both countries terms of olive grove regulation considering their multifunctionality, it is useful to implement agronomic indices estimate sustainability. The Soil Loss Tolerance Index (SLTI) Productivity (SPI) two such indices. We calculated Protected Designation Origin (PDO) Norte Alentejano (Portugal). SLTI index was adapted specific variables analysed (i.e., SLTIog). values obtained were compared with those previously estimated for PDO Estepa (Spain). negative impacts erosion underlying agricultural practices on sustainability became evident, resulting decreased soil productivity at regional level. SLTIog showed higher crops, being a realistic tool analyse A loss tolerance detected integrated due shorter age cultivation Portugal, incipient impacts. These provide information degree erosion, allowing farmers decision-makers apply maximise groves.
