Dr Edmeades commenced his science career in 1977 at MAF Ruakura, initially his research interests were on soil acidity and liming.
In 1985 he was awarded an ANZAC Fellowship and spent a year at the University of Queensland studying the effects of aluminium toxicity on pasture plants.
In 1988 he was appointed group leader (Soils and Fertilisers) at Ruakura and in 1991 became the National Science Program Leader (Soils and Fertiliser) in the newly formed AgResearch.
After 20 years in his role as a soil scientist at Ruakura Doug left institutional science in 1997 and established his own science consulting business, which has evolved into agKnowledge.
Doug's vision for agKnowledge is clear; it's purpose is to bring to the New Zealand farmer independent, objective, science-based solutions in the areas of fertilisers, soil nutrient management and environmental compliance.
Dr. Edmeades has published 90 scientific papers, several books, booklets and pamphlets and countless popular articles.
