Tender Description
Hort Innovation is seeking a suitably qualified, experienced and capable delivery partner for the project: Investigating soil pH and nutrition as possible factors influencing pink rot in potatoes – a pilot study (PT19000).
The primary objective of this pilot project is to determine whether there is a causative relationship between pH and soil nutrients with pathogen load and disease severity of pink rot, with a view to providing insight into whether this should be researched in more depth. Specifically, the pilot aims to:
- Determine whether levels of acidifying (particularly ammonium based) fertilisers influence pathogen load and disease expression
- Determine whether increasing the pH, such as through the addition of lime, has a suppressive effect on pathogen load and disease expression
- Understand whether nitrogen, calcium and other soil nutrients levels play a role, independently of soil pH, in suppressing or exacerbating pathogen load and disease expression
- Providing recommendations as to whether pH and fertiliser use should be explored in more depth for improved pink rot management.
