The impact of GNSS technologies on agriculture – the case-study of New Zealand
The article explores a wide range of agricultural applications of GNSS offered by different New Zealand companies
How agriculture changed over time
Almost from the very inception of humanity, agriculture has been an integral activity of our society. Throughout millennia, people have found ways to improve farming efficiency. The first breakthrough came with the mechanisation of the sector through the introduction of tractors and other agricultural machinery. The next leap forward was the result of the application of fertilisers and pesticides as well as the use of a more scientific seed selection approach. Later on, advancements were generated through the shift to precision agriculture with a greater focus on monitoring and data management.
Right now, we are taking yet another step forward – towards digital farming. This entails embracing a paradigm of unprecedented connectivity and digitalisation. In other words, more and more data are being collected via various remote sensors, centrally analysed, and subsequently used as a guiding force for further decision-making. At the centre of this whole process are numerous innovative companies which leverage GNSS and other space-based technologies to provide a whole range of revolutionary services for the agricultural sector. Many of these firms are based in New Zealand, which comes as no surprise considering the country’s worldwide fame for farming.
Who makes the innovations happen
For those who are not satisfied with traditional methods of measuring pastures, LIC offers a viable alternative. The company uses satellite imagery of the relevant piece of land, which is analysed and delivered to the client on the following day. The report will include not only the area measurements but also ample supplementary data on multiple factors like shadow and cloud coverage.
In contrast, Ballance provides a faster and safer way of spreading fertilisers precisely where needed. They employ a modern aircraft fleet in combination with the GNSS technology to accurately deliver the payload to the intended destination and ensure the best returns on the investments.
Another novel solution is offered by Halter, which developed a new more efficient way of managing cattle livestock. Their technology pairs a wearable smart collar that gets securely strapped on a cow and a smartphone app. As a result, a farmer can set up virtual fences, remotely move a herd, as well as receive timely health alerts.
Kiwifruit growing companies can make use of the vast services provided by GPS-it. Whether a new orchard design needs to be developed or an old orchard has to be converted, or perhaps a canopy area needs to be confirmed or updated, this and a lot more becomes possible through mapping and surveying by GIS, drone and aerial image technology.
Vineyards owners are not left out either since they can rely on the support of Aeronavics. The company makes use of the precise location data for a multitude of purposes ranging from crop health analysis and yield forecasting to weed control and damage assessment through the use of drones.
