The almond tree requires lower chilling hours than summer fruits and is usually grown in relatively dry or well drained areas (becauseof its sensitivity to diseases) such as the Lower Galilee, Izrael Valley, Samaria and Judea. Currently almond tree orchards cover an area of 6,000 hectares in Israel.
The trees gradually start bearing fruit from the third year onwards and the fertigation varies according to the trees’ age and season.
In young orchards where the trees do not yet bear fruit the recommended fertilization is between 100 and 150 Kg/hectare of Nitrogen, and one third of that quantity of phosphorus oxide, respectively, as for example in Tuv Solutions fertilizer, 21-7-0; fertigation should commence from March/April until October to ensure the development of the maximum foliage.
The normative fertilization quantity per season for a mature orchard is 250 Kg/hectare of Nitrogen, 50-60 Kg/hectare of phosphorus oxide, and 300 Kg/hectare of potassium oxide.
In April when the soil temperature increases above 18°C the addition of iron chelate fertilizer – Ferrogat in a quantity the equivalent of 10 Kg/hectare of solid iron chelate is recommended.
Where required, 40 – 80 liters/hectare of Zinc-Gat chelate should be combined with the fertilizer at a proportial rate during the continuous fertigation procedure.
