We are absolutely delighted at the calibre of speakers coming together for LandWISE 2018 – Technologies for Timely Actions. They have a wide range of backgrounds, work in a range of different sectors looking at a wide range of different things.
We’ve put information about the speakers on our discussion (blog) posts. Here, they are presented as a list with links so you can follow as you please.
We are grateful for the support of AGMARDT, McCain Foods and Heinz-Watties for helping bring our international speakers to New Zealand.
The story began four years ago when we had a crop of onions at the MicroFarm. To get a good look at the crop LandWISE Manager, Dan Bloomer climbed up the irrigator.
“The view when you get 7m up in the air and look down is very different to what you see walking around, and I saw massive variability throughout the crop,” he said.
“I could understand some of it but a lot more I couldn’t explain. A colleague was playing around with imaging and smart phones and he made an application where we could drive up and down the rows and map the percentage canopy cover. I talked about it with Onions NZ Research Manager Jane Adams who thought it would be quite useful and could lead to greater understanding of variability in onion crops.”
We then partnered with Plant and Food Research with support from Onions New Zealand and the Sustainable Farming Fund to do a project aimed at studying that variability.
Bruce Searle, crop scientist with Plant & Food Research, designed a research approach to get the data we needed to make some practical applications.
“We wanted to figure out where the variability comes from and how much of it is something that a grower can control. So we looked at the different factors that might influence variability and worked through the contribution of each to the overall variability,” he says.
“A lot of it comes down to individual plants growing at different rates – something that the grower can’t do a lot about. However, factors that influence getting good crop establishment are critical to reducing variability, and once the crop is up you can look at poor performing areas within in the crop. The tool that Dan has been working on captures that information so that you can map the field and make some decisions.”
We have done items with Showdown Productions before and have enormous respect for their work. You can see the result of the onion interviews on Rural Delivery, TVNZ1.
His role includes managing the R&D portfolio for the industry and ensuring the outcomes from it are integrated into commercial crop management programmes.
Tim has a strong track record as a technical researcher and advisor in crown research and in industry. LandWISE first worked with Tim to understand slug migration patterns in no-till and strip-till cropping paddocks.
In his LandWISE 2018 presentation, Tim will introduce “Smart tools to improve orchard drainage“. This is a new MPI Sustainable Farming Fund project, in which LandWISE is partnering with NZAPI to investigate high precision drainage in existing orchards.
Severe wheel ruts are common especially in wetter seasons. The immediate problem of tractor access for bin shifting is compounded by poor conditions for pickers and the less obvious impact of fruit rots increase. In more severe cases the ruts greatly increase picking costs as the use of mobile hydraulic picking ladders is made difficult, unsafe or impossible. In some cases, harvest costs are reported to have doubled.
Despite numerous attempts to rectify puddles and mud, the problem remains. The project will adapt and pilot use of precision technologies to survey, design and implement surface drainage plans that minimise ponding risk and reduce these negative impacts.
These will be supported by guidelines for wheel track management to provide a secure base for harvest traffic. This will become even more critical as the industry automation with picking platforms and robotic harvesters.
Bruce Searle is well known to LandWISE regulars having been on the Board for many years and an active contributor at many conferences and other events.
A crop physiologist in the Integrated Crop Production Systems group, Bruce leads the Plant & Food team researching onion crop development and modelling. His group is responsible for recording the life histories of 2,000 individual onion plants!
These data have informed development of an on-line tool to assess crop performance and help growers understand if crop development (and yield) is limited by established population, plant growth or both.
The collaboration with LandWISE has combined detailed plot scale work with whole paddock surveys to help Onions New Zealand growers understand the drivers of crop variability.
A small trial within this project looked at fertiliser rate and timing options when canopies are variable. Can we reduce rates in small canopy areas and still get the potential yield?
The 2018 conference sees the wrapping up of three years of Onions NZ research in partnership with Plant & Food, much of the activity being undertaken at the MicroFarm. LandWISE has captured numerous paddock scale images of the onions crops using satellites, UAVs, sensors and smartphones. This has given insights into which tools have strengths for what purposes at what crop growth stages.
Using algorithms proposed by Plant & Food, LandWISE developed the on-line tool SmartFarm which allows smartphone captured crop development data to identify different management action zones and give guidance to the degree of variability.
Dan is particularly interested in soil and water issues, how we can continue to benefit from farming while maintaining or enhancing profitability and environmental health.
In recent years his attention has been drawn to precision drainage technologies, and he uses OptiSurface to understand and quantify ponding and erosion risk in paddocks and to design solutions for surface drainage.
Dan actively scouts people, technologies and problems, identifying opportunities to bring them together to effect change on farm. As such, he has initiated LandWISE’s research and extension programmes including some new initiatives to be launched at LandWISE 2018.
Professor Daniel Drost is a vegetable researcher and extension specialist from Utah State University.
Dan Drost grew up on a small diversified animal and crop farm in Michigan (USA). He graduated from Michigan State University with a BS and MS degree in Horticulture. In 1983, he moved to New Zealand to teach Horticulture at Massey University. He returned to the US in 1987 to study at Cornell University where he was awarded a PhD in 1991 in Vegetable Crops and Plant Physiology.
Dan’s research and outreach efforts focus on small intensive production systems, sustainable and organic agriculture, and how land-use management impacts field and farm scale productivity. In his 25 years at Utah State, he has authored more than 150 extension and scientific articles on vegetable production and management practices, shared his understanding of farming systems with producers, scientists and industry leaders around the world, and focused his attention on sustainable vegetable cropping systems that are farm appropriate, socially acceptable, and economically viable.
One of our invited international keynote speakers, Dan was bought to New Zealand in conjunction with Onions NZ and Plant & Food Research to discuss sustainable production systems. His presentation to LandWISE 2018 was titled “Sustainable Crop Production: Field and Farmscape Management for Sustainability”.
Dan says,
“Insects, diseases, nutrient management, and weeds pose yearly threats to vegetable productivity and sustainability. This presentation will address how to best manage the farmscape (whole farm) to protect and mitigate these risks in field and farm settings. Using examples from a variety of vegetable crops (annuals, perennials, intensively managed) grown in a range of settings, I will outline how modern farms adapt to and deal with yearly uncertainty.“
Dan and colleagues have completed a lot of work on high tunnels for crop production. See a video here.
Armin Werner has a background in crop production sciences and as director of an Institute on Land Use Systems at ZALF in Germany worked on enabling new technologies for sustainable development.
Since 2013 Armin has headed the Precision Agriculture Science group at Lincoln Agritech (LAL), a subsidiary of Lincoln University in New Zealand. This covers Precision Farming (arable crops, pastures), Precision Livestock Farming, Precision Horticulture, Precision Spraying as well as Agricultural (Outdoor) Robotics.
Armin’s work has led him to create strong linkages and collaboration projects between various scientific disciplines and sectors including academic institutions, researchers and farmers.
Current projects include trans-disciplinary and technology-based research in NZ for various high-value crops; e.g. on fruitlet counting and sizing for apple crop load management. He manages also the Robotic Spearhead project of the National Science Challenge ‘Science for Technological Innovations’ that develops new knowledge for small, highly adaptable and flexible robots.
At LandWISE 2018 Armin will update delegates on the “Precision Grape Yield Analyser”, a research project on vineyard sensing and yield forecasting that Lincoln Agritech is undertaking.
Armin says,
“The ‘Precision Grape Yield Analyser’ is an ongoing interdisciplinary MBIE-project, supported by NZ Wine Growers and several vineyards. Grapevine yields can vary between seasons by a factor of 2 and New Zealand grape growers are keen to avoid unplanned high yields. To assess the expected yield on the block level very early in the season we develop sensing tools and computer models. AI-based sensor fusion combines data from optical and microwave ‘scanners’ and feed the results into a continuously learning, predictive computer model.
Aldrin Rivas is a Catchment Hydrologist at Lincoln Agritech. He has over ten years of professional experience in the fields of water and environmental science, engineering, and management; and has worked for private and government entities.
Aldrin has experience in denitrification in natural and engineered systems and will tell delegates at LandWISE 2018 about a Lincoln Agritech, ESR and Aqualinc project investigating woodchip bioreactors to remove nitrate from drainage water. Some say this is closing the stable door after the horse has bolted. Others say it’s catching the horse and putting it somewhere safe!
With a mixed background in engineering and science, Aldrin is involved in a variety of Lincoln Agritech projects including the Ground Water Mitigations project and the Transfer Pathways Programme.
His interests include:
• Groundwater
• Denitrification in the vadose and saturated zones
• Vulnerability assessment of freshwater resources
• Integrated catchment development and management
• Water supply systems and management
• Environmental and hydrological modelling
Taylor Welsh works at Plant & Food Research as part of it’s Biosecurity Research Group. Taylor’s work includes bee and pollination based research in Entomology and Embedded Systems .
Taylor is currently working towards a master’s degree in Electrical Engineering based at the University of Canterbury where he previously completed his BSc in Biochemistry and Molecular Biology.
Taylor and colleagues from Plant & Food Research and the University of California have developed a way to automate insect trap checking. They measure the wingbeat of an insect as it enters a monitoring (pheromone) trap and are building a library of data for relevant insects for the Asia Pacific region. The technology will hopefully reduce the need to manually check the thousands of traps used for biosecurity.
Matt Norris is a research associate at Plant and Food Research within the Sustainable Production (Field Crops) team in the Hawke’s Bay.
Matt has a background in soil science and chemistry and a keen interest in sustainable nutrient management including modelling nutrient losses from arable and vegetable production systems.
Matt is responsible for leading and managing a range of environmentally focused research projects. His primary focus areas relate to nutrient management, specifically quantifying N and P losses from arable and vegetable production systems. Additional areas of research include N mineralisation dynamics from dairy effluent amended soils and developing novel soil testing approaches for informing N management decisions.
Matt will present both a talk and a practical demonstration on a Quick Test for Nitrate, a way to rapidly determine how much available nitrogen is in the soil for crops to access. LandWISE and Plant & Food used this in our Onions NZ /SFF research this season to determine how much fertiliser we might apply when we had areas with different size canopies.
