A soil survey, soil analysis and report from a professional consultant will cost approximately $2500. The survey/analysis should determine:

• Soil structure and drainage.
• Soil pH or acidity.
• Soil fertility.
• Readily Available Water (RAW).
• Presence of residual chemicals which may affect future organic registration.
• Presence of nematodes and fungal spores which affect olives.

Horticultural investments are long-term. Preparing the soil to give the trees an optimal start is critical for good early production and long-term profitability.

The soil survey report should provide an assessment of the suitability of the site soil for olive production and recommend possible remedial action which will improve marginal sites:

• Application of lime to make soil more alkaline, less acidic.
• Application of gypsum to break down clay and improve drainage.
• Ripping to at least 600mm to improve drainage and root penetration.
• Application of fertiliser or compost to improve fertility.

Other aspects of site preparation which should be completed prior to planting are:

• Establishment of windbreaks.
• Building of water storage.
