From Agrilink to AquaSpy - A history of Agrilink
The founder of Agrilink had a simple goal: to become the Dell or Microsoft of the agriculture sector, to revolutionise farming by making available a host of web based services. By June 2009, when the company relocated from Australia to the United States of America, it had consumed over $50m AUD of venture capital without achieving its dream. This article provides an insight in to the history of the company and its many incarnations.
Company Incarnations
The history of Agrilink can be traced to a small company operating in Western Australia, Agrilink Water Management. After a number of years trading as Agrilink - Agrilink Holdings, Agrilink International, Agrilink Florida - the company morphed in to AquaSpy in 2008.
Agrilink Water Management
Agrilink Water Management was founded by Peter Moller in 1997 (Layden 2002). The company Moller had been working for closed its agriculture division and, rather than looking for employment, decided to start his own company. Agrilink Water Management began life as a neutron probe consultancy (Moller had been introduced to these then new devices by his former employer) providing irrigation management advice to growers in the south west of Western Australia. As Moller related to the Naples Daily News in 2002, after the company for whom he was working closed its agriculture division, he "had an entrepreneurial seizure one day, and thought I would go into business" [1].
When Adelaide based company, Sentek Sensor Technologies [2]introduced the EnviroSCAN capacitance soil moisture sensor, Moller signed on as a dealer. The company then switched from taking weekly neutron probe readings to consulting based on the continuous soil moisture data the new product delivered. This provided customers with far more information and helped increase the value of the services the company provided. At its peak the business employed Moller and two young consultant agronomists. Moller had ambitious plans for the company and called in a business consultant to help prepare a business plan to drive the company forward. Progress stalled when his newly appointed business manager and one of his agronomists left in quick succession.
During his time as a Sentek distributor, Moller worked closely with Nigel Robinson, the then Marketing Manager at Sentek. Sentek's soil moisture probes utilised multi-core cable to connect back to a data logger. The logger would be removed every week and taken back to the office to download the stored readings in to a computer running Sentek's software. The system had two major shortcomings: firstly the cable was susceptible to damage from machinery and lighting and secondly, users often returned to the site a week later only to discover that they had not correctly primed the logger prior to replacing it in the field, meaning a week of lost data. There had to be a better way.
Agrilink Holdings
Agrilink Holdings was added to the Australian companies register on 1/5/1997 (ACN 078 399 158, registered name AGRILINK HOLDINGS PTY LTD). Robinson had by then left Sentek and was looking for new opportunities.
Earlier in the year, Sentek had received a visit from Austrian Company Adcon Telemetry [3], to explore opportunities to distribute Adcon's range of telemetry products in Australia. At that time the equipment was principally used for automatic weather stations, providing information not just on current climate conditions but, through the use of a number of models, providing warnings on the likely outbreak of a number of plant pests and diseases. Sentek at the time could not see a place for the products in its range.
Robinson approached Adcon Telemetry ande secured the distribution rights for their products in Australia. Robinson and Moller reached agreement on allowing Robinson to take on the Agrilink name and business model and Agrilink Holdings was born.
The company initially operated from an office in Melbourne St, North Adelaide, South Australia. The first employee, an office administrator named Tanya, joined Nigel from Sentek. The second employee, was also an ex Sentek staffer, Wayne Hogben. The third employee, Gavin Wheatcroft was employed fresh from university. Having developed a likely hit list of companies likely to be interested in weather data, the company set out installing weather stations on a trial basis on grower's properties. In each district one of Adcon's telemetry base stations would be deployed to collect the data from the radio data loggers which formed the heart of each station. A computer in the company's office would dial out via landline telephone each day to collect the data and store it on Adcon's addVANTAGE software. If at the end of the trial the customer wished to keep the weather station, it would be left on site and the customer invoiced; if not, it would be moved to another property.
Whereas in Europe interest in disease management was high, the same could not be said for Australia. Sentek's efforts had proven that there was however a good market for soil moisture monitoring, however many potential customers were put off by the need to install cables to link the probes back to a central data logger. Robinson could see what Sentek had failed to: the opportunity to use Adcon's telemetry products to deploy radio linked soil moisture probes. However Adcon's current family of radio data loggers were too expensive to be used for the purpose. What was needed was a lower cost, short range radio. Use of the Sentek soil moisture probes was out, mainly because the company was not interested in developing a new interface to replace the proprietary interface used to date by their probes.
Adcon agreed not just to make a new low power radio, but also to begin development of a capacitance sensor. The latter development was shelved when Agrilink decided to take the task on themselves.
The C-Probe Corporation
Developing new products is not cheap. To take on the task, Robinson needed funding and he was introduced to Adelaide's emerging Venture Capital sector. Using market growth predictions developed during his time at Sentek, Robinson convinced a group of local investors to provide him the money to develop his own sensor - the C-Probe, with which he could compete against Sentek.
The C-Probe Corporation was created by the directors of Agrilink, to create an impression of independence between the company as the local telemetry provider and the new soil moisture sensor. According to SOWACS, a web site established to promote soil water sensors, the C-Probe was "manufactured in Australia under license from the C-Probe Corporation of California" [4]. The two companies shared common directors and Agrilink Holdings was awarded the master distribution rights for the sensors.
Responsibility for developing the new sensor was passed to ADD, an Adelaide based electronics company specialising in electronic promotional signs and displays. The brief for ADD was to create a sensor which was compatible with Adcon's radio equipment and used the same form factor (and hence installation tools) as the Sentek probe.
In 1999, the company relocated to 7/69 Burbridge Rd, Hilton, South Australia. Soon after, Adcon delivered their new radio, the A720 addIT, but delays in the development process meant that the new soil moisture probe was not quite ready. As a stop gap measure, early customers were given Watermark soil moisture tension sensors, connected to Adcon's Watermark interface module. By the second quarter of 1999 the C-Probe was finally ready for market. Staff were trained up on installing the probes, using techniques and tools which borrowed heavily on those developed by Sentek.
Sentek had developed a business model based on selling hardware to its dealers who in turn backed the hardware up with consultancy on irrigation management. The inability of the capacitance sensors to accurately record soil moisture levels meant that interpretation of the data was beyond the average farmer. The consultant would analyse trends and inflections in the data and set full and refill points. In the first year the consultant would get rid of gross errors and in the second start managing irrigation to the new full and refill points. Robinson needed an experienced agronomist to provide this scheduling advice to his customers and called on the services of Peter Moller.
The company could service customers in South Australia on its own, but to service those further afield, the company needed distributors. Agrilink Water Management became the first, switching allegiances away from Sentek. Serve-Ag in Victoria and Tasmania followed soon after as well as Sunraysia Environmental in Mildura and Cropsol Consulting Services in Griffith. A linkage was also opened up with Agrotop in South Africa.
By late 1999 the company had grown to 12 staff and plans were put in to place to quickly grow further.
GolfLinx
To coincide with its refocusing on the turf market, Agrilink opened a new branch called GolfLinx. Although not registered as a separate company, a Board of Management was formed to run GolfLinx. To build credibility with the golf sector, former profession Bruce Devlin was appointed to the board [5]. Equipment was installed on 6 high profile courses to give the company reference sites. Back in Australia a GolfLinx division was created to target Australian courses.
Despite a belief that “our soil moisture and salinity sensors, combined with our telemetry and software, are the best in the world” neither the US or Australian arms could achieve any traction in the golf market and the division was quietly disbanded in early 2009.
AquaSpy Group
In November 2007 the "Agrilink" brand was dropped in favour of a new name - Aquaspy Group. The company's latest soil moisture sensor had been christened the Aquaspy and the company adopted that moniker. The board cited the reason for the change as being that the previous name was "too strongly linked to agriculture and didn't reflect other products and services. This includes a turf and golf course business that is tapping a large and receptive market" [6].
At the time of the name change, AquaSpy claimed to have “more than 50,000 AquaSpy sensors in use around the world” [7]. It is not clear whether this figure is related to the actual number of probes sold of to the actual number of sensors installed on the probes. As the new probes have 10 sensors, the number of probes sold would be much lower..
The Aquaspy brand was mated to a new corporate web site, with revised look and feel. Underneath it all was the same staff and systems, including the quickly fading AgWise platform.
Product Development
Soil Moisture Sensors
The Series 1 C-Probe
The Series 1 probe was built around an 8-bit peripheral interface controller (PIC) chip. Development of the firmware for the probe was sub-contracted to a local electronics engineer who received a royalty on each unit sold.
To match the capabilities available in Sentek's software, new features had to be made available in the addVANTAGE program. The modular nature of the program meant this could be achieved with a new module - the C-Probe Extension.
Although it took a few incarnations to get the probe working properly, many units are still working ten years later.
C-Probe Series 2
In 2000 an application was lodged with AUSIndustry for a research and development grant to develop a soil salinity sensor {Reference needed}. Sentek had already started work on their Triscan probe and Robinson wanted to ensure his company had something to equal it, hence the S-probe project. The new project could be used not just to build a salinity probe but also to update the design of the soil moisture probe. This coupled to a desire to save on the royalties being paid to the developer of the series 1 C-Probe, led to the development being carried out in house.
By this time ADD had closed down and some of the former staff had been taken on at Agrilink. As Adcon had commenced looking at the SDI-12 interface as an option for its future products, Agrilink decided to base the new probe on this protocol. Each sensor element would act as an SDI-12 sensor and communicate through a simple pass through board to an external SDI-12 logger. For compatibility with Adcon’s older analogue radios, a board was produced which could convert the output from 6 SDI-12 sensors to 6 analogue signals.
Sentek had not patented the EnviroSCAN, but had patented a dual frequency probe for detection of salinity. Agrilink had to be careful that their new salinity probe did not breach this patent. The $1.5m project (half from AUSIndustry and half from inside the company) failed to deliver a working product. As an indication of complexity of the relationships involved, many years later, Sentek's TriSCAN may be used as a trending tool but does not provide any measure of the actual soil salinity.
If the Salinity probe development seemed ambitious, that pales compared to development of the nutrition probe or N-Probe. A share of the AUSIndustry grant money was hived off to fund investigation of a multi-level nutrient sensor which would be able to track movement of nitrogen through the profile. Spectrometry was emerging as the new tool for investigation of nutrients and for assessing parameters such as wine grape quality and this technology was seized on for the N-Probe. Like the S-Probe, the N-Probe never made it to market. C-Probe Series 3
One of the powerful features of Sentek's original EnviroSCAN probe was that the unit was completely configurable. Users could purchase a probe in a variety of lengths and then fit sensing elements at 10cm intervals along the column. Agrilink took the same approach with the C-Probe. Flexibility always comes at a price and in this case that was cost of production. Each probe had to be custom built to order. A column was first cut to the required length, a bus bar fitted and then sensors attached to the bus bar. The completed probe was then tested and run through a normalisation process. The variable frequency oscillator used in the sensor boards is subject to a number of variables: variation in tuning coil, variation in sensor ring dimensions, variation in thickness of the tube wall and more. The completed probe would be placed in a test tank containing air and then in one containing water. This would set the low and high frequency limits for the oscillator. To account for the variability, the normalisation process stored these high and low readings and pre-scaled all future readings between them on a scale of 0 to 100 Scaled Frequency Units. The C-Probe series 3 attempted to cut some of the manufacturing steps down by switching to a fixed design: 50cm with 5 sensors or 100cm with 10 sensors. Probes would be supplied pre-normalised and the preferred installation technique was switched from through-the-tube augering to an over-sized hole and slurry. The probe would be sealed to remove the need for regular maintenance - a bugbear of previous variations.
Design of the Series 3 probe was once again performed in house. The Series 3 was represented an evolution of the Series 2 rather than a new design. The Series 3 had probably the shortest life of any AquaSpy product, being replaced very quickly by the Series 4 probe.
AquaSpy Sensor and AquaBlu
The AquaSpy Sensor (also for a while called the AquaOne) marked Agrilink's first serious foray into the turf market and its release coincided with a shift in company strategy away from the agriculture market, towards the commercial and domestic turf markets. The original AquaSpy was a single level probe designed specifically for use in turf. The paddle design gives some clue to its internal layout: being a flattened version of the rolled up sensor design to be used in the Series 4 probe. The AquaSpy was sold with a partner product, the AquaBlu which together could be used to control irrigation based on soil moisture status. For some reason the first design of the AquaBlu relied on 12V DC power, whilst the majority of multi-station irrigation controllers used 24V AC power supplies. The product was put on hold while a quick 24V AC to 12V DC power adaptor was designed and built.
The AquaSpy sensor was viewed favourably enough to win Best New Product Award at Irrigation Australia Ltd’s biennial Exhibition in 2006 and a People’s Choice Award on the ABC’s New Inventors programme [8]. Staff were employed to build sales of the units through the major retail hardware outlets. Unfortunately volume sales remained elusive.
