2025 Canterbury Finalists: Matt and Heidi Hart of Pye Group (Longlane Farm) – Arable

Canterbury arable famers Matt and Heidi Hart are redefining sustainable agriculture through their dedication to innovative farm practices and a deep commitment to soil health. 

The 890ha (830ha effective) Longlane Farm is owned by Leighton and Michelle Pye, with its management taken over by Matt in 2003. Since then, he has prioritised soil health and transformed the mixed cropping and lamb finishing operation. This includes significantly improving crop yields and quality while reducing the farm’s environmental impact. 

About 25% of Longlane’s sown area is dedicated to vegetable production, with the balance used to grow cereal and ryegrass. The main crops are potatoes, juicing carrots, wheat, barley, ryegrass and peas. 

Key to Matt and Heidi’s success is a meticulous approach to data-driven decision-making. They use advanced technologies including soil moisture probes and variable rate fertilisation to tailor inputs to specific land conditions – optimising the use of resources and minimising waste. 
 
The judges were particularly impressed by the couple’s willingness to experiment with new ideas. One example is the introduction of nature strips as an effective way of naturally controlling pests – ultimately reducing the farm’s reliance on chemical pesticides.  

By incorporating cover crops and minimising tillage, they have also improved the property’s soil structure, increased organic matter, and enhanced water retention. 

The Hart’s have a strong commitment to staff wellbeing, with policies implemented to manage fatigue, promote safety, and foster a positive work culture. By investing in training and development, Matt and Heidi empower their team to contribute to the farm’s ongoing success. 
 
External experts are regularly used to objectively provide advice on the farm’s strategy and performance. This, combined with the innovative approaches being employed, are boosting the farm’s production while also contributing to a more resilient and environmentally friendly agricultural sector.
