Humic acid and Liquid Sea Minerals were applied to peanuts. 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.
The Trial
The 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 supply many nano minerals in small amounts. Generally, these are not used in farming today. The humic acid is soil biology food.
Later in the crop, leaf sugars, as measured by refractometer* showed a 20% increase in treated rows.
Results
There was only a small yield increase, but there was a marked increase in nut size. This gave almost 50% increase in large Jumbo grade, which commands a premium price.
This gave $520/ha increase in returns to the farmer.
