Graeme Sait, Principal of Nutri-Tech Solutions based on Queensland’s Sunshine Coast, visited the Island in November 2022 and delivered some excellent workshop presentations as well as leading field excursions to local properties.
Mr Sait has generously provided the attached article Chasing the Biggest Bang as a generic summary of pathways for improving nitrogen, phosphorus and potassium levels in soils. The article highlights how complex are the interactions between physical soil, organic materials, mineral nutrients, micro-organisms and plants. Even experienced gardeners and farmers are encouraged to read the article.
In the video of this talk (external link), he reports that previous analysis of some 40-50 samples of soil from around the Island showed five minerals including copper and boron to be deficient from all, no exception.
In this video of the inspection of the Selwyn Pine Rd property of Dr and Mrs Geoff Edwards (external link), he explains that he sees no evidence of unthrifty plants that cannot be explained by inadequate nutrition.
In the video of this field inspection, he explains the critical importance of a healthy ‘microbiome’ and the damage that processed food does to the human metabolism (external link).
