Fertiliser considerations fieldday: Whangarei, 29 June 2023

NZ Avocado invites you to join us on Garry and Charlene Cliff’s orchard to discuss some of the key considerations around fertiliser application and discuss growing avocados under shelter. Thursday, 29 June 2023 from 1.00pm – 3.00pm at 65 Tatton Rd, Whangarei.

Growers may have recently received fertiliser recommendations following soil and leaf testing in autumn. With financial and environmental sustainability a keen focus at the moment, what are some of the key considerations to critically assess current fertiliser use? Garry and Charlene also have some avocado trees under tunnel house which provides some interesting context to discuss the potential for alternative growing systems in our industry. NZ Avocado staff will be present to share information and guide discussion on the following topics.
