Certified organic fertilization for avocado
Avocado is one of the most sensitive crops to salinity and chlorides. Incorrect fertilization can cause leaf phytotoxicity, tip necrosis and significant yield reduction. Ecoganic offers solutions certified for organic farming, especially indicated for this crop.

Why can't avocado receive chloride fertilizers?
+
Avocado has extremely low tolerance to chlorides (less than 7 meq/L of Cl in the soil saturation extract). Using fertilizers with potassium chloride (KCl) causes leaf burn, tip necrosis and premature fruit drop. Ecoganic potassium comes from organic sources rather than muriate of potash.
When is nutrition most critical in avocado?
+
Critical moments are: flower induction (late summer/autumn), flowering (spring), fruit set and bulking. Post-harvest is also important to replenish tree reserves for the next flowering.
Can drip fertigation be used in avocado?
+
Yes. Ecoganic liquid products are 100% soluble and compatible with drip fertigation. Avocado responds very well to fractioned fertilization through the irrigation system.
