Why is Zespri trialling biochar?

Biochar is a much-touted but rarely used carbon-rich material derived from organic waste, great for soil health. Kind of like charcoal it’s the result of slow, anaerobic burning. But it has not yet been widely tested in perennial tree or vine crops. Until now. Zespri has been trailing biochar as part of new innovation programme. This project aims to assess the impact of biochar application in kiwifruit orchards when applied with and without the addition of compost, looking at its effect on soil characteristics and fruit production, as well as the economics of application. The results will give growers increased confidence when trialling this promising product and also reinforce Zespri’s leadership in sustainable farming practices. Vincent spoke to Eu Jin Cheah, Global Leader, New Values Opportunities and Bryan Parkes, Head of Innovation Acceleration, both at Zespri. See the innovation fund here:
