Our fertilization recommendation for growing fertile avocado trees in Israel and South Africa
Soil type: light to medium.
Plant density: 400-600 Trees / ha.
Expected yield: 10 -20 t/ha.
The recommended average rates of nutrients (Kg/ha).
N | P | P2O5 | K | K2O |
---|---|---|---|---|
150-250 | 25-40 | 57-90 | 170-290 | 205-350 |
These rates should be split as follows:
I. Early spring
- 50 kg N/ha, it can be applied as 2-3 applications of:
ammonium nitrate, totaling 150 kg/ha, or urea, totaling 110 kg/ha. - Half the annual rate of the P, as 2-3 applications of:
Haifa P, totaling 67 L/ha, or MAP, totaling 50 kg/ha.
II. During the active growth season
Nitrogen (100-200 Kg N/ha) is best applied in 8 - 10 applications by fertigation in the form of ammonium nitrate (or urea) and Multi-K.
Potassium - all potassium should be supplied as Multi-K (KNO3) in five monthly applications.
III. Autumn
Half the annual rate of the P, as 2-3 applications of:
Haifa P, totaling 67 L/ha, or MAP, totaling 50 kg/ha.
Annual program
Fertilizer | Applications | Total Amount | |
---|---|---|---|
Time | No. | ||
Ammonium nitrate | Spring | 2-3 | 150 Kg/Ha |
Multi-K | Active growth season | 5 | 450-750 Kg/Ha |
Ammonium Nitrate | Active growth season | 8-10 | 120-300 Kg/Ha |
Haifa P | Spring and Autumn | 2 | 134 L/Ha |
Multi-K - 13% N and 46% K2O (38% K).
Ammonium nitrate - 34% N.
Ammonium Sulphate - 21% N.
MAP= mono-ammonium phosphate (12-27-0).
Haifa P= phosphoric acid, 85%, 0-61-0.
