Cotton Yield Benefits using BioAg Liquids [Trial Report]

From 2013-2017, BioAg's liquids soil inoculants and foliars were independently trialled to test their ability to effect yield results in cotton crops.

The following is a summary of the 5 years of results.


To evaluate the impacts on cotton yield when using BioAg fermented microbial liquids over the top of standard fertiliser applications.


In-field use and on-farm demonstrations in Australia’s southern cotton valleys had identified positive yield responses when applying BioAg’s fermented liquid cultures on cotton crops.

In order to get more reliable, repeatable, year on year results, independent, small plot replicated trials were required. Given the trial controls required, the globally renowned Agricenter International in Memphis, Tennessee, USA performed the trials#.

Fertiliser rates were based on standard practice in the area.

Products Trialled

Treated plots received applications of BioAg’s Fermented Microbial Fertilisers; Soil & Seed (S&S), Balance & Grow (B&G) and Fruit & Balance (F&B).

Soil & Seed was applied on the soil at planting.

Balance & Grow was applied as a foliar at first bloom (5 to 7 weeks after planting).

Fruit & Balance was applied as a foliar at peak bloom (2 to 4 weeks after applying Balance & Grow).

#When reading the trials’ results please note additional cotton trials with other rates of application and fertiliser use were also performed.

Summary of Results

In year 1 (2013), trials were more extensive so as to identify the optimal rate of use for Soil and Seed.

Having completed the 2013 trials all subsequent years used a constant full program of BioAg liquids.

In 2013, 2016 and 2017, growing conditions for cotton were better than average meaning cotton crops suffered fewer stresses. The 2014 trial was conducted in a poor growing year; while in 2015 growing conditions were average.

Irrespective of the conditions experienced the BioAg treatments increased cotton yields. The largest response was achieved when growing conditions were average.

Yield Response

The USA trials have shown that the use of BioAg liquids over the top of a fertiliser program increases yields.

While yield in each season varied, each year provided a beneficial return.
