Research Highlights
Design and Methods
This study examined the rate of avocado tree nutrient uptake from the soil.
Four cultivars (Booth-8, Choquette, Hall, and Hass) were grown in commercial orchards.
Each tree received 13 lbs of 17-17-17 (N - P2O5 - K2O) split into two applications. One application was at the start of the rainy season in June and the other was at mid-growth.
Avoacado fruit were analyzed for mineral contents, yields, and a variety of quality components.
Results
Hass avocados had the highest rates of nutrient uptake.
- Nutrient uptake per 22 tons fruit:
- Hass
- 114 lbs N
- 45 lbs P2O5
- 207 lbs K2O5
- Choquette
- 67 lbs N
- 30 lbs P2O5
- 133 lbs K2O5
- Hall
- 64 lbs N
- 22 lbs P2O5
- 131 lbs K2O5
- Booth-8
- 81 lbs N
- 26 lbs P2O5
- 120 lbs K2O5
- Hass
These results show that nutrient removal rates can be expected to differ between cultivars.
