UK Trial Showcases Smart Fertiliser Strategy

Teamwork in the Field

As part of international trials for FertiSpot, C.J. Cox Ltd and AMAZONE Ltd partnered with Pearce Seeds to evaluate fertiliser efficiency and yield performance under British soil and climate conditions.

 The trial tested varying DAP (diammonium phosphate) dosages and compared Ferti Spot with traditional band application across eight 900 m² plots. The field was drilled using the AMAZONE Precea on 5th May 2025 and monitored throughout the growing season. Upon maturity, each plot was harvested and weighed using a feeder wagon equipped with weigh cells to ensure accuracy.

The results were impressive: reducing the fertiliser dose rate by 30% and using AMAZONE FertiSpot, the trial achieved a £ 45/ha fertiliser saving and a 7.2 t/ha increase in fresh yield. This translated into a total return of £ 386/ha.

Looking ahead, C.J. Cox plans to repeat the trials across different soil types and seasonal conditions. Will Lunn from Pearce Seeds commented, “The trial was very good and proved we could reduce fertiliser usage without impacting yield – cutting costs and benefiting the environment.” This is particularly relevant in the Poole Harbour catchment area, where eutrophication and algal blooms are ongoing environmental concerns.
