Humic acid and Liquid Sea Minerals were applied to avocados.

At harvest, the fruit weight was increased by 10%. By supplying soil biology foods, the soil structure and nutrient availability improved, thereby allowing larger nuts to be produced. Bio-Booster was not used in this trial.

Trial

This trial was conducted near Bundaberg in 2020. Applications of Liquid Sea Minerals 5 L/ha and Humic Acid 15 L/ha were applied by boom spray soon after emergence and followed by overhead irrigation.

Treated area – 4 beds with 8 rows equal to 1.25 hectares. The Sea Minerals supplies many nano minerals in small amounts. Generally, these are not used in farming today. The humic acid is a soil biology food. Later in the crop, leaf sugars as measured by a refractometer,* showed a 20% increase in treated rows.

Result

There was only a small yield increase but there was a marked increase in nut size. This resulted in almost a 50%increase in large Jumbo grade, which commands a premium price. This translates to $520/ha increase in returns to the farmer.
