Avocado: what to measure and why
A long-term orchard investment. Avocados are shallow-rooted, very sensitive to waterlogging and salt, and reward steady moisture through flowering and fruit set.
Also known as Parachichi
Growing conditions
The ranges avocado cares about
General agronomic ranges. A soil test and your agronomist decide the final numbers for your variety and site.
| Factor | Range | Note |
|---|---|---|
| Soil pH | 5.5–7.0 | Typical range |
| Drainage | free-draining only | Waterlogging invites Phytophthora root rot |
| Salinity tolerance | sensitive (~1.3 dS/m) | Chloride causes leaf-tip burn |
| Critical water period | flowering, fruit set and early growth | Stress causes fruit drop |
Risks
Where avocado loses yield
Root rot
Over-irrigation on heavy soil kills trees slowly. Moisture probes at two depths show whether water is draining or sitting.
Salt burn
Borehole water with chloride shows as leaf-tip burn. Monitor water EC.
