Trial aim 

To evaluate the impact on corn yields when applying BioAg liquid biostimulants to fertiliser regimes representing Grower Standard Practice (GSP) and GSP
less 15% nitrogen.


In-field use and demonstrations in Australia’s cropping regions had identified positive yield responses when applying BioAg’s fermented liquid cultures on a range of crops.

In order to get more reliable, replicable, year on year results we needed to run independent, small plot replicated trials.

Agricenter International was engaged to perform a range of trials on behalf of BioAg to evaluate the impacts of applying BioAg’s liquid biostimulants over crops of Dent Corn.

The downloadable report details the outcomes of these trials.

Fertiliser rates were based on grower standard practice in the Tennessee area.

Products used in the trials

Treated plots received applications of BioAg’s Fermented Microbial Fertilisers; Soil & Seed, Balance & Grow and Fruit & Balance. 

Soil & Seed was applied on the soil at planting. Balance & Grow was applied as a foliar in  number of equal treatments at various stages of leaf unfolding.  Fruit & Balance was applied as a foliar as one treatment when the 8 or 9th leaf was unfolding.

Summary of results

The overlay of a complete BioAg biostimulant program on Grower Standard Practice for the production of Dent Corn delivered the best yield results for all treatments trialed.

It provided higher yields than Grower Standard practice every year.

Benefits were achieved across all seasons.  Irrespective of a high or low yields for grower standard practice, treated plots yielded higher and delivered financial benefit in each year.

Basis the outcomes of the range of trials performed it is evident that consistent results were achieved when utilising both soil applied and foliar biostimulants.

Yield response


The USA trials have shown that the use of BioAg liquids over the top of a fertiliser program increases yields. While the yield in each season varied, each year provided a beneficial return.
