The concentration of fluorine (F) in New Zealand pastoral soils is increasing as a consequence of Phosphorus(P) fertiliser application, and there is concern over the long-term impact of this F on animal and soil microbiological health.
Ongoing soil F monitoring to underpin comprehensive soil F management practices requires an accurate and simple test to quantify both the total and bioavailable concentration of F in soil. In this study, soils were collected from various locations across New Zealand, representing different soil orders and land uses.
The research describes a simple analytical method for total soil F concentration. It found that for New Zealand soils at risk of F contamination, 4 mol L−1 NaOH extraction gives reliable results.
The researchers propose that 0.01 mol L−1 CaCl2 extraction should be adopted as a standard method to assess the bioavailable F concentration of New Zealand pastoral soils.
The Fertiliser Association of New Zealand and Dairy NZ funded development of the Nutrient Management Adviser Certification Programme (NMACP). This industry-wide certification aims to ensure that advisers have the learning, experience and capability to give sound nutrient advice.

An interest in farm sustainability and sustainable fertiliser management was the key driver behind Massey University student Theané de Klerk’s decision to focus her Master’s degree on New Zealand’s agricultural phosphorus budget. Theané is one of three students that the Fertiliser Association of New Zealand is currently supporting.
