FAQs about olive grove fertilization
How many applications does organic olive need per year?
+
Organic olive needs 6 to 8 applications a year spread across the phenological cycle: 1-2 at bud break, 2 at pre-bloom and bloom, 1-2 at set and bulking, 1 at ripening and 1 post-harvest. The exact frequency depends on the state of the grove, the soil type and the weather of each season.
When is fertilization most critical in olive?
+
The two most critical moments in olive are pre-bloom (BBCH 54-57) and fruit set (BBCH 71-75). At pre-bloom, biostimulant and nitrogen supply determines the number of viable flowers and the set rate. At set, calcium, nitrogen and potassium supply is decisive for fruit development and retention.
Can olive be fertigated with Ecoganic products?
+
Yes. All Ecoganic liquid products are 100% soluble and formulated to be compatible with drip fertigation without clogging filters or emitters. Soluble powder products (such as NITROTECH 16) should be dissolved beforehand in a drum before being fed into the irrigation system.
