Our Research and Development team are constantly conducting trials and measuring results. Research and analysis of infield grower success is important as it ensures we understand best application methods, best integration and best rates of application. We have paid careful attention to grower feedback as well as scientific and replicated trial results.
As we increase our understanding of biological mechanisms and the complex world of soil microbiology it has become increasingly clear that the growers who use our inputs over time reap ever increasing rewards, tapping intot he buildup and accumulative natatre of how how biological inputs build system robustness. One off dosage grower trails do not measure the real mechanism of releasing the system potential.
Our long term users have played an important role, with many running their own ongoing trials with good stewardship.
Australian growers are fast realising the advantages they can get from using our range of advanced bio-stimulants.
Through our extensive research in controlled, scientific environments such as the university laboratory and through important infield analysise, we can increase nutrient availability. Petrik Soil Technology formulations work through biological pathways and outperform conventional methods in productivity and whole system benefits.
Nitrogen Fixation Research
A research project in conjunction with the University of Sydney Pulseford Laboratory, one of the leading research labs on microbial plant growth promotion in Australia, for biological nitrogen fixation is entering into the second year of planting.
The work is expanding into Sorghum in the Liverpool plains as well as following on in Sugar Cane in Mackay and Maize in Shepparton. 65 soil samples were collected through the season last year - these are from replicated plots with various nitrogen rates with and without the Petrik inoculants. We have extracted DNA from the soil biology in the rhizosphere and this will be assessed for differences in the microbe population.
The concept here follows on from the work in Sugar Cane carried out by John Reghinzanni in Tully and Ingham. John also worked with the staff at the Sunfix centre. John found 1000 times the population of the free living nitrogen fixing microbe Azotobacter at lower nitrogen rates, indicating that higher nitrogen rates inhibited the activity of these species. The primers used in the DNA extraction can also be selected for species increasing phosphorus availability and beneficial fungi.
We are doing this work to quantify the mechanism we know we already have from working with clients like Joe Flemming at Paraweena Pastoral company who grew two trophy winning wheat crops last season on 25% of industry standard nitrogen. Joe has been using the Petrik system for 8 years now.
