This paper was presented by Dr Sophie Parks at the International Symposium on Mineral Nutrition of Fruit Crops. Dr Parks is a Senior Research Scientist with the NSW Department of Primary Industries and leads the Clean Coastal Catchments blueberry nutrition research team.
NSW DPI Research & Development Officer Luke Jewell looks at the benefits and challenges involved in retrofitting irrigation reycling in the protected cropping sector. Converting to a closed recycling hydroponic system can dramatically cut water use and reduce fertiliser inputs, but careful planning is needed to avoid risks to production.
Dr Sophie Parks discusses the efficacy of various sources of nitrogen in fertigated blueberry production. As Dr Parks explains, supplying the 'right source' of nitrogen is the first step in the 4Rs approach to plant nutrition.
NSW DPI Soil Scientist Justine Cox and Development Officer Jeremy Bright review the current recommendations for reducing soil movement in macadamia orchards and outline their research on mulching options to lower the risk of sediment and nutrients moving off farm into water ways.
Dr Lukas Van Zwieten evaluates the effectiveness of enhanced efficiency nitrogen fertilisers, the benefits of slow release fertilisers, organic amendments, and biological nitrogen fixation, and the development of rapid testing for potentially mineralizable nitrogen (PMN), with regard to their role in improving productivity and reducing nutrient pollution
NSW DPI Soil Scientist Justine Cox discusses the significance of soil texture in managing blueberry mound nutrition. Considering soil texture is equally as important as testing for soil nutrients, as soil texture critically affects the plant’s capacity to access nutrition applied through fertigation.
