The BBG’s Fish Emulsion Demonstration project was completed in 2013 however, we have received funding to continue the Fish Emulsion Project. You can track its progress on the AgTrialSites website.

The project used a liquid fish emulsion product as an alternative method to lessen the stubble burden in cropping by improving palatability for stock and stimulating soil microbiology to increase the rate of stubble breakdown. The liquid also adds important trace elements to the soil and increases stored soil carbon.

Results were presented in 2013 at an informative day hosted by the Blackwood Basin Group at the Qualeup Hall, near Kojonup .Presentations showcased the results and findings of the effect of spraying a liquid fish nutrient product onto stubble to encourage microbial activity to breakdown wheat and canola stubbles.

The product used was a locally manufactured WA product that was developed to utilise fertile waste products from WA fisheries. Demonstration sites included wheat and canola stubble plots in Qualeup, Kojonup Shire, that were sprayed with the application after harvest. Rounds of soil sampling to test for microbial activity, salinity, pH, trace elements, and soil nutrients and carbons were taken before and after treatment.

Stock were allowed to graze trial areas to enhance knockdown of stubbles and greater microbial action.

“After a very short ten week period, there were some positive results that can be derived from the soil analyses where the product was applied.” says Project Officer Sara Weir. “This is encouraging and exciting to see as it may be another stepping stone for future trials conducted over a longer period of time”.

Keynote speakers at the event included Deb Archdeacon, Agronomica; Rob Read of Marine Solutions who manufactured the product; and Peter Keating from Bioscience who tested the soil samples.
