South African nut farmer turned to innovative IoT solutions in order to better manage his crop of Macadamia nuts, taking into account everything from soil moisture levels through to vehicle maintenance management. With the help of Thingstream’s cost-effective, reliable, secure and low-power IoT connectivity technology, Thingstream Solutions Partner, Pylot is enabling Robert Carlton-Shields to turn his farm into a model of efficiency and productivity.
In developing markets such as Africa, the Middle East, Southeast Asia and Latin America, the potential of IoT is limitless; IDC predicted that IoT in Africa and the Middle East will see a growth of 15% to $7bn in 2018. This growth is already becoming evident in South Africa where businesses are being forced to adapt to the new business models brought about by IoT. But not all IoT solutions are equal…
Robert Carlton-Shields bought his Macadamia nut farm in 2011. The farm is approximately 100 hectares which comprises 52 orchards, all of varying sizes. The farm currently produces approximately 200 tonnes of nuts per year ranking it among one of the larger producers of Macadamia nuts in South Africa.
Macadamia trees are particularly susceptible to stress. Periods of prolonged drought (as was the case in South Africa in 2015) and overcompensating with watering, frequently results in stressed Macadamia orchards. The results can be extremely damaging to yield and quality.
Unless you are prepared to have a very dedicated (and expensive overhead) workforce out in the field, then optimizing yield and tree welfare is a real challenge to manage successfully.
Having bought his farm in 2011, Robert decided to use technology to see if there were efficiencies to be gained by deploying a number of moisture sensing probes across his farm to help make timely irrigation decisions. It soon became clear that the probes, while accurate, needed as much time and effort (as physical observation) to manage properly. Each probe needed to be visited, have its data downloaded and then be brought back for interpretation. By the time a meaningful decision on irrigation needs could be made up to a week could have gone by.
Robert persisted and the next technical evolution was to attach a SIM to each of the farm’s 52 probes. While connectivity provided data collection efficiencies, each SIM had its own data plan (which needed to be manually ‘topped up’) and each probe needed to be initiated to collect the data. Add in multiple operators supplying the SIMs, plus the need to interpret the data, and the solution was still impractical to manage in order to gain efficiencies.
Mid 2018, enter Thingstream, via their South African (specialist farming) System Integrator partner, Pylot. Thingstream’s solution offers a single global SIM offering, meaning there are no roaming charges – one SIM accesses hundreds of operator networks. Data is sent, in this case from the moisture sensing probes, over the voice channel of the local network operator. Using the voice channel is significantly more cost effective than using a dedicated data channel and provides a higher level of security. Data is collected, analysed and presented on the customer’s dashboard – all in real-time.
“I can now efficiently manage the irrigation of a 100 hectare farm and optimise machinery workflow, all from one cost effective and reliable IoT dashboard.”
– Robert Carlton-Shields, owner of R&K Estates Macadamia farm
Thingstream’s solution not only allows for the real-time collection and presentation of moisture level data (allowing for timely irrigation decisions), but going forward, trackers will also be fitted to the farm’s machinery ensuring that farming workflows can be optimised for vehicle maintenance and even pest and fungus spraying performance.
What benefits are envisaged having started the switch to Thingstream’s solution? Broadly speaking, the farm can now optimise costs, labour usage and yields and quality:
“For IoT solutions out in the field there was previously just the option to use 3G. Then low power network (LPWAN) providers such as LoRA, Ingenu and SigFox became available. The challenge with these LPWAN’s is that they are not readily available in the agricultural areas, and it becomes a long and costly process of setting up bespoke access points and high sites to provide these new LPWAN services. For example, we’ve run into planning issues for the masts and this can be just to provide a trial of the service – it’s simply not quick enough or cost effective. Thingstream has a ubiquitous coverage footprint, is low power, cost effective and can be up and running in hours. Combine that with the data collection and reporting platform they provide and this is an IoT revolution.”
