Dr Nigel Swarts is head of Horticulture at the Tasmanian Institute of Agriculture. He is interested in the field of tree physiology and specifically tree crop nutrition. Nigel leads two collaborative projects on nitrogen management in tree crop production systems, and is currently supervising eight PhD students and two honours students. Nigel has a background in Conservation Biology and Natural Resource Management with research focusing on rare and endangered orchids from across Australia. He has a strong track record in the field of orchid conservation with two highly cited review articles and a book published in 2017.
Biography
Before joining the University of Tasmania, Nigel held a postdoctoral position at the Botanic Gardens and Parks Authority in Perth, Western Australia. From 2008 to 2010, Nigel managed a conservation biology research program at the Kings Park Botanic Gardens and completed research into the mycorrhizal relationships of Western Australian orchids. He completed his PhD with distinction on the conservation of critically endangered orchids with the University of Western Australia in 2008 (supervised by Prof. Stephen Hopper and Prof. Kingsley Dixon).
Nigel's research has led to a better understanding of the role of mycorrhizal specialization in the ecology and rarity of the Orchidaceae. His work has contributed to the development of new approaches to the conservation and recovery of terrestrial orchids based on key biological and ecological requirements for orchid survival. Nigel led a team of volunteers in the ex situ culture and propagation of Western Australia's orchids. Upon moving to Tasmania in 2009, Nigel developed a similar conservation and research program at the Royal Tasmanian Botanic Gardens. Nigel joined TIA in May 2011 and is currently Sandy Bay location leader for the Horticulture Centre and leader for Tree Crops working group.
Nigel has an established track record with publications in international peer reviewed journals, spoken at major international conferences, regularly presents at industry conferences and field days, received over $4.5m in grant funding, and supervised honours and masters students to completion. Nigel also holds an adjunct senior lecturer position at the University of Western Australia.

Research Themes
Nigel's research on tree physiology aligns to the University's theme of Environment, Resources and Sustainability. In his two key research projects, the management of nutrient resources are considered in the context of a productive landscape. In this case, the productive landscape is apple and cherry orcharding in the Huon Valley, one of Tasmania's key horticulture regions and high value production industries. The management of nitrogen in these industries is critical to producing high quality fruit for domestic and international sale. Additionally, mismanagement of nitrogen can have negative environmental outcomes through groundwater contamination or increased fertiliser induced greenhouse gas emissions (N2O). Nigel's research aims to determine a complete nitrogen budget for apple and cherry production that accounts for nutrient cycling, optimum timing to meet resource demand and mitigation of environmental impacts.
Collaboration
Nigel is currently leading two collaborative projects which are aimed at obtaining a better understanding of nutrient management in horticultural tree crops.
The first project funded by HIA forms part of the Productivity, Irrigation, Pests and Soils (PIPS) program and involves collaboration with Plant and Food Research New Zealand.
The second project, forms part of the More Profit from Nitrogen program funded by the Rural Research and Development for Profit initiative by the federal Department of Agriculture and Water Resources and is a cross RDC program investigating more efficient use of nitrogen.

FRDC Sea Urchin Fertiliser Project (2021 - 2024)$199,996
- Description
- This project will investigate the commercial upscaling of processing sea urchin waste for use as an agricultural fertiliser. This project was primarily aimed at benefitting the seafood processing industry by purchasing and establishing a waste processing facility, analysing waste products for their biochemical composition and very preliminary research trials in an agricultural context. The processing facility can produce two main products from the processing waste: a powder of dried and crushed shell waste and a liquid from gut waste.

Improving grapevine quality and yield through improved vine nutrition and pruning (2017 - 2020)$59,112
- Description
- The current proposal will establish nutrient and irrigation treatments with the aim of stabilising yield across seasons. Preliminary work by TIAs Grape and Wine Team over the past two years has established that nutrient application in vineyards could well be contributing to the lack of yield consistency.An additional decision which faces growers is the choice around timing of pruning, and the style of pruning, either cane or spur pruning. This decision is further complicated by the introduction of mechanical cane and spur pruners to the state. Under cane pruning systems, knowledge about cane selection is also vital.The proposal is tightly aligned with the WA strategic plan 2015-2020, priority 1, Increasing demand and the premium paid for all Australian wine, specifically strategy 3 which is to build Australian Grape and Wine Excellence.

Waste to profit in urchin fisheries: developing business opportunities to ensure fishery sustainability and safeguard reef dependant fisheries from destructive urchin grazing (2017 - 2018)$52,102
- Description
- Increasing the viability of urchin fisheries is particularly important for the range-extending Centrostephanus rodgersii which is threatening the productivity and profitability of the lucrative abalone and rock lobster fishing grounds as far south as the Tasman Peninsula (south-eastern Tasmania).Waste products from urchin fisheries account for over 85% of the harvested biomass, with up to 180 tonnes of sea urchin waste produced annually. Developing saleable by-products from waste will increase the viability and profitability of urchin fisheries by 1) creating new business opportunities 2) reducing waste disposal and transport costs and 3) enabling increased harvest levels temporally (longer seasons), spatially (further from port) and at an increased density. Cost effective control of Centrostephanus is a key priority of the Tasmanian Government as well as the Tasmanian Abalone and Rock Lobster Council. A profitable Centrostephanus fishery is seen as the best way to achieve this. However, profitability in the fishery is currently low given the species lower roe quality. Methods to reduce costs and increase profitability are vital for a prosperous fishery and control of destructive urchin grazing.Initial studies have indicated that urchin gut contain high levels of bioactive molecules with anti-thrombotic activity. Similar activities recently conducted in abalone processing waste have developed separation strategies for anti-thrombotic and anti-coagulant molecules. These methods are being patented by CSIRO and FRDC for future commercial engagement. Preliminary trials indicate that the separation strategies developed for abalone can be extended to urchin processing waste isolating molecules with nutraceutical grade bioactivity. Initial biochemical analyses have also shown that urchin testes contain essential micronutrients deficient in Australian soils providing a basis for the development of agricultural products. Developing business opportunities from the vast quantities of urchin waste is seen as an effective way to increase the viability of urchin fisheries while simultaneously reducing costs associated with urchin waste management and decreasing urchin numbers in valuable abalone and rock lobster fishing grounds.

Optimising nutrient management for improved productivity and fruit quality in cherries (2017 - 2020)$2,252,506
- Description
- This project addresses priorities 1, 2 and 4 of the .., and will improve farm gate profit for growers by conducting research and demonstration trials in the field which benchmark the sources and scale of nitrogen losses across a range of horticultural industries nationally. It will profit and environmental outcomes for industries by developing new management practices based on a better understanding of nitrogen use efficiency (NUE) from manure and crop fertiliser practices. In horticultural industries, past studies have shown that 88% of the total nitrogen inputs (300 to1.2 t N per annum) from fertilizers and manures can be lost and this is having major environmental consequences and losing profit for industry. Unknowingly for growers, most of this N is being leached into waterways or being lost to the atmosphere as the potent greenhouse and ozone degrading gas, nitrous oxide or wasted as nitrogen gas. Our past research on a limited scale, DAFF (NANORP) and HIA funded fertigation and NUE projects have shown that up to 44% of applied N fertiliser can be lost to the atmosphere and 50% of applied nitrogen fertilisers leached into sensitive waterways from the apple and vegetable industries. They have also shown a 50% reduction in nitrogen emissions and gains of $1500/ha by using enhanced efficiency fertilizers and manures inhibitors which prevent losses of nitrogen from soil systems. This project will expand these findings and benchmark industries use and wastage of nitrogen. Improved soil management strategies developed by this project will provide industries with new fertilizer and manure technologies (Enhanced efficiency fertilizers) and information to better manage soil water and nutrient dynamics in horticulture cropping land.

Global master class in horticulture (2016 - 2021)$3,234,368
- Description
- Future growth and prosperity of the production horticulture industry in Australia will continue to rely a resilient, adaptable and innovate workforce that is equipped to change with industry demands. Many horticultural industry leaders have identified a need for specialised and flexible training opportunities to enhance the broader workforce. The University of Tasmania, through the Tasmanian Institute of Agriculture, has arguably Australias best integrated horticultural RD&E and education and training framework. The University of Tasmania will utilise combined strength and reputation with that of Lincoln University (NZ) in agribusiness, and the experience of the Wageningen Academy to develop and deliver a Global Master Class in horticulture that gains a premium reputation nationally and internationally within 5 years. This will involve working closely with Hort Innovation and Wageningen Academy to fashion a high-quality course with the appropriate flexible delivery styles and formats that meet the demand of industry. This collaborative and innovative approach to education and training will be evaluated through research in learning and teaching, and the insights gained will inform approaches to professional development in the Australian horticulture industry. This new knowledge will be communicated in professional and disciplinary conferences and publications.

Improved productivity and profitability for the Australian apple and pear industry (2015 - 2020)$925,000
- Description
- This project in collaboration with Plant Food Research will develop a multi-season N budget underpinned by fertigation research that builds on findings from the current fertigation project (AP12006) and a decision support tool that will guide advisor/grower optimisation of irrigation and fertigation application for all major national regions. Fertigation research will include the continuation of a major ongoing nitrogen and irrigation trial at Lucaston Park Orchards in Southern Tasmania. This trial was established for AP12006 and fertigation and irrigation treatments will continue for the next four growing seasons creating one of the longest intensive nutrition trials ever completed in the POME fruit industry. Undertaking litter decomposition studies, labelled N research and monitoring tree performance and N leaching will enable us to determine for the first time a complete N budget for commercial apple production. This research will provide an understanding of how fertiliser application approach, rates and timings can be managed to best satisfy the trees N requirements, mitigate leaching and optimize productivity without a cost to fruit quality. The decision support tool backed by a meta-model incorporating data from field N fertigation trials, multi-site regional soil parameterisation, climate and tree physiological datasets will provide growers with a reliable assessment of their orchards soil, water and nutrient status based on their irrigation and fertiliser inputs. Growers and advisors will be trained in the usage of the decision support tool. This research will enable growers and advisers to explore different irrigation and fertilizer strategies and management practices for different soil types and climates in order to optimize yield achievement without cost to quality.

Diversity and abundance of arbuscular mycorrhizal fungi in native and managed landscapes in Tasmania (2015 - 2017)$17,175
- Description
- This is an application for operating funds to support a PhD project (Mrs Reham Mohammed). This project will investigate the distribution and abundance of native arbuscular mycorrhizal fungi (AMF) in southern Tasmania, using a range of molecular approaches. Information of AMF in Tasmania is poor however interest in the role of soil biology for both conservation and productive landscapes is growing. AMF are symbionts that colonise plant roots and can play vital roles in plant functioning and soil health, both in natural and managed landscapes. The project aims include identification of key AMF species and exploration of how factors such as land use, soil type and season alters the diversity and abundance of these species
