High density olive grove?
This is a system for cultivating olive trees that began in Spain in the 1970's, driven by a group of agronomists led by D. Jose Humanes. It is characterized by single-truck open-vase shaped olive trees, which enable collecting the entire harvest using truck-mounted shakers with reverse umbrella catchers. In addition,, plant density per hectare can be anything form 200 to 450 trees, with orchard lanes at least six meters (20ft.) wide and a distance of 4 to 7 meters (13 to 23ft.) between trees. From an economic standpoint, olive oil costs derived from this system are more advantageous than int he case of traditional olive groves.
