Proven yield increases – Tony Parr’s success with Maxstim Agriculture+
Case Study
For farmers like Tony, increasing yield and quality while managing input costs is a top priority.
Farming 800 hectares, including 150 hectares of potatoes, Tony was initially sceptical about biostimulants. However, with agrochemical availability declining and fertiliser prices rising, he decided to trial Maxstim Agriculture+ under a strict testing protocol.
The results
A 10.64% increase in marketable yield—equivalent to £700 extra per hectare.
Key findings from Tony’s three-year trial:
- Year 1: 6% yield increase—enough confidence to expand the trial to 25 hectares
- Year 3: 10.64% marketable yield increase
- Consistently improved tuber skin finish, increasing potential profit margins by 10-20%
Tony has now adopted Maxstim Agriculture+ across his entire potato crop, proving that biostimulants can deliver real, farm-scale results.
