Oio Vivo - maslinik


Our olive grove of 56 hectares with 15,000 trees is situated in a prime location for olive growing, at an altitude of 60-120 m above sea level, only 4.5 km away from the sea. Laid out between Vodnjan in the north and Pula in the south, in the southern part of the Istrian peninsula with the beneficial flow of warm sea air from the Rasa Bay in the east and the Brijuni Islands in the west.


Oio Vivo - Oleum Maris

Oleum Maris is a young company founded in 2005 on the grounds of diversity, tolerance and unity.

The company owners showed courage in embracing a new beginning – by planting the largest olive grove in southern Istria on previously fire devastated land. Together, through their own means and with the help of the local community, they opted for new challenges, starting a company based on the principles of socially responsible business. Continuous training, care about quality, innovation in collaboration with professional institutions, are the basic principles of Oleum Maris. The company’s vision is to offer their customers an overall experience related to olive growing and creating high quality olive oil produced at an attractive, well positioned location.

Map of the olive grove

Olive grove is divided into a regular orthogonal grid, recalling the Roman legacy of land centuriation – a method of land measurement, within which five native olive varieties, plus the the two Italian ones, are cultivated.

Inovatori su u proizvodnji korisnih strojeva i alata kojima mogu poboljšati održavanje maslinika, te su tako osmislili prototip stroja za zalijevanje maslinika i gnojenje koji posredstvom ugrađenih senzora štedi gnojivo ispravno dozirajući vodu kojoj je dodan tekući humus.

Kompanija surađuje sa Agronomskim fakultetom u Zagrebu, Veleučilištem u Poreču, Institutom za poljoprivredu i turizam, također, u Poreču, te Otvorenim učilištem Pula – Diopter – vezano uz programe edukacije odraslih osoba u maslinarstvu.
