The trial showed that the use of a slow release fertiliser based on “reactive phosphate rock” as used in BioAgPhos® and Superb® has a cumulative effect over time. Continual applications either annually or biennially work to improve pasture dry matter production.
8.3 t/ha yield achieved after stock grazed on the crop in August. +17% yield increase above the control
BioAg’s Balance & Grow along with gibberellic acid were key ingredients to maximising winter production. Addition of N further improved yield but not as cost effective.
In this trial at Dadswell Bridge BioAgPhos S10 followed by BioAg Superbdelivered more dry matter in the second year, as well as in total across thetwo years.
Randomised block with 4 replications. RPR & SSP applied at 4 different rates. By year 3, RPR outperformed SSP at all application rates.
RPR achieved dry matter yield production of approximately 1,000 kg/ha more than the other eight participating products.
