DRIP IRRIGATION FOR OLIVE TREE

Olive tree water requirements 

Nowadays, irrigation is a fundamental activity in modern olive cultivation, its role becoming increasingly focused on obtaining maximum results with the least use of water resources. Maximum crop water requirement 2 to 3 mm/day.

Seasonal crop water requirements: intensive 350 – 600 mm/ha/year or traditional 600 – 800 mm/ha/year)

It should be noted that the potential of combining irrigation and fertigation results in a substantial reduction in the phenomenon of alternation of the yield, which is typical of the olive tree.

This practice known as Fertigation, applies the mineral fertilisers necessary for the physiological and productive functions of the plant. This technique cannot be done without foliar diagnostics and soil analysis.

For fertigation use only water-soluble fertilisers such as:

• Urea (46% N)
• Potassium nitrate (13% N & 46% K2O)
• Monoammonium phosphate (12% N & 61% P2O5)
• Ammonium nitrate (34% N)

Irrigation system for olive trees

Irritec® offers a technical solution for sub-irrigation, and in particular for intensive 300-400 trees/ha olive cultivation, a type of olive tree cultivation that today represents the majority of new plantings.

The advantages of this irrigation technique are many:

  • Reduced losses through evaporation, by localising the water close to the roots, sub-irrigation saves water compared to an above-ground drip system by 30%;
  • Reducing the agronomic burden, it allows the free passage of mechanical means for grass cutting, treatments and superficial soil
    tillage (maximum 25 cm depth);
  • Reduced weed development;
    Increased fertiliser efficiency by localising nutrient solutions close to the root system;
  • Reduction of damage to driplines caused by insects, animals or vandalism.

What does a sub-irrigation system involve? 

For the irrigation of the olive grove, the recommended system is buried drip irrigation system. This involves:

  • Buried dripline
  • Main filtering system with automatic backwash device.
  • Water meter to monitor the flow rates of individual sections.
  • Air relief valves at the highest points of the manifolds to prevent a siphoning effect.
  • Drain manifold, located at the end of the driplines, to carry out the necessary purging and maintenance of each sector.

Driplines buried at varying distances from the stem depending on the crop and time of planting and at a depth of 20-40 cm. Driplines with a chemical barrier to root intrusion (Rootguard) self-compensating driplines with very high resistance to obstruction.

Sub-irrigation (on new plantations) is to be used with the aid of surface relief irrigation for the first two years of the olive grove’s life, allowing the young root to develop properly in the first two years.

A practical example of how to drip irrigate olive trees

Here are the Irritec products you need to drip irrigate olive trees

1

ROOTGUARD MULTIBAR™

The characteristics of the pressure compensating dripper make Multibar® an ideal product for installations in areas with large differences in ground level, where extremely long line lengths and constant flow rates are required in every portion of the system and high delivery precision typical of high-quality crops.
