Online Avocado Yield Impact Support Tool Available

  • Sep 22, 2023

An Avocado Support Tool, designed to help growers optimize tree nutrition for greater yields, is available online at

The online service is simple to use. Growers input leaf data, which is sent to Dr. David Crowley for analysis. A customized, confidential report is provided to the grower identifying each site’s current yield potential, and specifically ranking each nutrient element and its quantitative importance in affecting the site’s potential fruit yields. The detailed report shows results for macronutrients (Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulfur) and micronutrients (Zinc, Manganese, Iron, Copper, Boron, Sodium, Chloride). The report is emailed to growers with a short turnaround time.

The website includes instructions concerning how and when to collect avocado leaves for sampling. The statistical analysis cost is $50/site.
