Growing olive trees dates back more than 6,000 years, hence the knowledge about olive trees cultivation has "deep roots". The nutritional and health values of olives and olive oil are highly appraised, creating great demand for high quality extra virgin (EV) olive oil.
Here is a sample of the knowledge that can be found in Haifa's crop nutrition guide:
- World olive oil consumption rose by 1 million tons during 1996-2009.
- Olive oil products dominate the marketplace and 80% to 90% of olives produced are devoted to olive oil production.
- Traditional, extensive, rain-fed olive plantations yield ranges between 7 and 14 ton / ha, which transforms to 1,700 – 2,400 liters of oil.
- Olives grow well on almost any well-drained and aerated soil with pH values of 6.5 – 8.5. Therefore, sites where water stands during rainy periods or where ground water is shallower than 1.2 meters deep should be avoided.
- It is possible to achieve the same optimal volume of canopy per hectare, and consequently yields, with various spacing variations.
- The most important fact to bear in mind when pruning, is that the olive tree usually bears fruit on the previous year's new growth, and never bears in the same place twice.
- If commercial yields are desired, greater amounts of water will be needed, provided that soil humidity does not become excessive.
- Olive trees are very sensitive to over irrigation and will not perform well in waterlogged soils.
- During the first years of the plantation, a premium controlled-release fertilizer, such as Multicote™ Agri 17-9-16+2MgO augmented with trace elements, is recommended.
- Alternatively, soluble fertilizers may be used with high efficiency, especially by Nutrigation™ (Fertigation). If the fertilizers are broadcasted separately, be sure to water very well after application.
- Nitrogen (N), phosphorus (P), potassium (K) and boron (B) are generally the most critical nutrients in the mineral nutrition of olive orchards.
