Biostimulants as Alternative to Phosphate Fertiliser
A three-year farm trial in Cambridgeshire has demonstrated the effectiveness of biostimulants as a replacement for conventional phosphate fertiliser without compromising crop performance.
Arable farmer Russell McKenzie initiated the trial due to soaring Diammonium Phosphate (DAP) prices. He sought to maintain yields while reducing input costs through biological alternatives.
"This led to a three-year project comparing our standard 200kg/ha DAP programme with 1 litre/ha of Luxor in the first year,"
In subsequent years, the approach was adjusted to 0.5 litres/ha of Luxor combined with 0.5 litres/ha of Calfite Extra to enhance nutrient use efficiency in second and third wheats.
The trial offers a sustainable and cost-effective alternative for growers, proving biostimulants can be an effective substitute for phosphate fertiliser.
Author's summary: Biostimulants replace phosphate fertiliser effectively.
