Dean from On Point Drones has been involved in Aerial agriculture for the last 14 years with the initial 11 years as a commercial helicopter pilot. With a shift in lifestyle, Dean started an agricultural Drone company in 2021, specializing in Spraying and Spreading. Dean’s Drones work year-round throughout Victoria and Southern NSW spraying, spreading and baiting. Over a wide range of Agricultural crops including Pasture, Cereal, Rice and Corn. Dean’s clients are always coming up with new and exciting ways to use Drones, for example applying algaecide to water bodies, applying and removing Whitewash in horticulture etc. On Point Drones also holds contracts with Forestry and other government bodies. Dean sees drones in agriculture continuing to grow rapidly in many ways that couldn’t even be imaginable. Over the last 12 months Dean has been working closely with Hardi in the development of Drones for weed detection. Dean sees this becoming big part of his business, with the development of green-on-green weed detection becoming very accurate. This is already being used with a variety of different spray rigs. Dean is always happy to talk about where the use of drones in agriculture currently is and where its heading, it is also a great way to find new ideas from clients and how these ideas can be made possible. Please feel free to ask Dean any questions you may have regarding drones in agriculture or anything related to aerial application.

Fiona Conroy.jpg Fiona Conroy

Fiona Conroy and her husband Cam Nicholson run Knewleave Partnership, a 400ha grazing operation running Angus cattle and fine wool Merinos on the Bellarine Peninsula near Geelong. Their farm operation has a strong focus on productivity, animal welfare and environmental management They have undertaken extensive tree planting, pasture improvement, paddock subdivision, soil testing, stock water reticulation, livestock performance recording as well as monitoring changes in biodiversity. Measuring and monitoring soil fertility and moisture levels, pasture cover and growth rates, animal performance and condition score are just some of the tools used to make on farm decisions, manage risk and respond to changing climatic conditions. In recent years they have been exploring the opportunities and challenges around carbon accounting and reporting at a farm level so they can respond to emerging market signals for lower carbon emissions and stronger environmental credentials. Fiona has a Bachelor of Agricultural Science and have previously worked with the Victorian Department of Agriculture and as a journalist at The Weekly Times. Fiona has been a farmer member of the Victorian Agriculture and Climate Change Council which is a ministerial advisory council that provides independent advice to the Victorian Minister for Agriculture on how the agricultural sector can prepare for, and respond to, the impacts of climate change.

On returning to the New England area Bill teamed up with wife Jacqui to evolve their farming business into a specialty grass certified backgrounding and finishing system – and in doing so turned a traditional New England farm into a business capable of turning off slaughter cattle all year round at high stocking rates and with no supplementary feeding. A search for solutions to get better insight into cattle growth rates led to Bill developing Optiweigh over the years 2014-2018. In 1019 he proceeded to commercialise Optiweigh and has gown it into a business that has now sold over 700 units around Australia and into 5 other export destinations.

Picture1.jpg Kieran Ranson

Kieran Ransom is a part time consultant after retiring with 40 years of agricultural extension and research experience with the Victorian Department of Primary Industries, mainly in Bendigo. He has expertise in sheep and crop production, financial analyses of farming systems, soils and climate and rainfall uncertainty and whole farm system modelling.  In 2012 an analysis of climate, seasonal and price risk using real farm data with the Victorian DPI indicated some farming systems have been resilient to the climate and price uncertainty over the previous 13 years of highly variable seasons. These lucerne-crop farming systems reduce price risk by marketing three commodities; meat, wool and grains and reduce winter crop seasonal risk by profiting from unpredictable summer storms. Kieran has worked closely with farmers in facilitating discussion groups, delivering technical information and conducting field trials. Early in his career he helped in the conduct of 35 wether trials and more recently 25 Prograze courses. He has also conducted 8 grazing management experiments and demonstrations. Kieran has authored many technical documents. He is the principal author of two books and three chapters in books. He has also presented and published at over 40 conferences. Recently he has worked a volunteer with the Elmore Field Days projects comparing breeds of ewe for prime lamb and wool production over 10 years.  He continues to work with the farming community as a BestWool-BestLamb group facilitator.
