AquiMax® Improves Trunk Diameter and
Tree Height of Oranges

2016 SynTech Research, Sanger, CA
Valencia Oranges for Juice on Sandy Loam
Randomized Complete Block Design with 6 Replications

A study was established on newly-planted Valencia orange trees grafted onto lemon tree stocks in summer of 2016. AquiMax® was injected into a micro-sprinkler irrigation system, which was randomized so that experimental treatments were applied individually to single trees. Trees were watered to replace either 100% or 70% of water lost through evapotranspiration (ET). AquiMax® was applied on 10 August and 26 August at a rate of 1 gal/ac.

Trunk diameter was measured prior to treatment application, and again at the end of the season. AquiMax®-treated trees had a larger % increase in trunk diameter and tree height after one season of applications. These trees will continue to be treated for the next 3 to 4 years as they mature and begin to produce fruit.

This study was conducted on newly-planted Valencia oranges to investigate how AquiMax® influences tree development from planting through fruit-bearing. Performing replicated research with advanced technology requires a complex network of micro-sprinkler lines to ensure that treatments are applied individually to each tree through chemigation process.

AquiMax® Increased Trunk Diameter at 100% ET Replacement

Percent increase of trunk diameter from 7 July, 2016 to 23 November, 2016.

AquiMax® Increased Tree Height at 70% ET Replacement

Percent increase in tree height from 7 July, 2016 to 23 November, 2016.
