Smart irrigation system to improve kiwi production in Italy

Italy is the second major kiwi producer after China with a saleable production around 448.000 tonnes last year. Both countries with New Zealand, Chile and Greece suppose the 93% of worldwide production by a research of the Centro Servizi Ortofrutticoli (CSO).

The CSO informed in 2015 that the grow surface for kiwi on the Mediterranean country was 24.440 ha, most of them in the regions of Lazio, Pedemont and Emilia Romagna.

FAMOSA is an Italian company that works on technology-based support for agriculture, offering solutions for crop monitoring and management. They have developed wireless sensor networks, based on Libelium technology, in a kiwi plantation with GPRS and Sigfox to develop accurate irrigation strategies for farmers.

Comparing GPRS to Sigfox

Kiwifruit is one of the most sensitive fruits in terms of quality which is given by size, sweetness and dry matter. In order to reach the best quality, the Rivista di Frutticoltura e di Ortofloricoltura considers that it is essential for farmers to develop a good irrigation strategy to attain marketable products and to reduce product losses.

Agriculture organizations are deploying cutting-edge technologies in their plantations to improve processes, to maintain high quality standards and to ease farmers daily works. “We have chosen Libelium Waspmote Plug & Sense! Sensor Platform for its wide range of sensors and the easy development of software for data acquisition and transmission”, has stated Massimo Noferini, CEO of FAMOSA.

For this project, the company has installed two different wireless sensors to monitor soil water status to plan irrigation in a kiwi orchard. Data has been recorded with the same system but information has been transmitted to the platform by two different wireless connection: GPRS and Sigfox. The main aim has been testing reliability and costs during 2016 kiwi growing season.

Two Waspmote Plug & Sense! Smart Agriculture have been deployed with watermark sensors in different depths to control soil moisture with fruit diameter sensor to measure the size of the fruit; and temperature and humidity sensors to monitor environmental conditions. One of the sensor platforms is connected to a GPRS shield and the other with Sigfox. The first one represents the classical widely used data communication network and the second one the rapidly diffusing LPWAN technologies.

The information collected by the sensors has been sent to esiFARM, FAMOSA’s platform, that includes both GPRS and Sigfox technologies. To manage GPRS stations however a server has had to be configured. In this case Meshlium IoT Gateway has been used embedding Meshlium Management System making data handling easier. Farmers can get valuable information to schedule irrigation timing to avoid stress conditions, which is fundamental on kiwi plants.

FAMOSA has detected some differences between both technologies after the deployment:

    • GPRS:
      • A server is needed to host data that has to be maintained by the local services.
      • There must be GPRS/3G/4G coverage.
      • It is needed power consumption hardware because GPRS node requires a long-duration battery pack or external power supply. The hardware needs to stay awake for a long-time and requires a longer communication session.
      • It needs a SIM card that usually takes some days to be activated. Even if international SIM cards are available, there is a strong dependence to a contract which make connections liable to changes and reliability.
    • Sigfox:
      • It dumps data to a unique service which is accessible worldwide: data can be managed autonomously or by an intermediate service.
      • Coverage is already diffused in Italy so it is not available everywhere although it is rapidly growing worldwide.
      • It doesn’t need a handshake step with the network, while based on an acknowledge response.
      • Communication is very short and allows the device to stay dormant for a long time allowing a much longer duration to batteries.
      • Registration is quicker than GPRS, based on an annual fee.

The final user has not been aware nor suffered the difference between the communication through GPRS or Sigfox. Battery pack proved to have a life long enough to cover the season both in Sigfox and GPRS devices. In general, any field deployment should be as simple as possible and have a ready and reliable answer during installation tests.

Precision Farming to make smart irrigation decisions

Developing technological projects in rural areas may involve several difficulties because of the absence of physical communication infrastructures and the costs which are often unaffordable. However, wireless sensor networks suppose a great opportunity because of the low installation, maintenance and also operative costs.

FAMOSA is collaborating with farmers to introduce the IoT approach with esiFARM in their fields. The platform allows to collect information from the sensor platforms and other information sources such as georeferenced cameras pictures or multispectral analysis of satellite imagery. EsiFARM includes models to help farmers in decision and alerts (irrigation, pathogens and maturation).

“Farmers were impressed by the ease of the installation, which proved to be able to give real-time and comprehensive information in less than one hour of full installation”, has argued Massimo Noferini, CEO of FAMOSA. During 2016 season between March and October the decision support system has worked well and continuously. Farmers have been able to monitor without interruptions soil water status to have irrigation always under control.

Intelligent efficiency: Turning data and energy efficiency into valuable assets

In the past, it has been all too easy to think of energy efficiency as a chore, a marginal ‘upgrade’ to existing infrastructure or processes that may save a bit on utility bills in the long run – and a few tons of CO2 or gallons of water for the environment too, says Craig Anderson

 

A recent paper by sustainability and energy efficiency research group GreenTech Media astutely noted that: “All around us, embedded in every commercial building, manufacturing facility and corporate campus, is a vast, untapped energy resource: efficiency.”

If we look at it this way, energy efficiency is a potential revenue stream of sorts – an underused asset that can be exploited to improve business performance and reduce unnecessary waste. You might put your coins in a pocket with a hole in it for a while, thinking it would be too expensive and time consuming to fix it, hoping not too much would fall out. But what if you were offered a repair that not only stopped the loss but actually added more coins to your pocket afterwards?

As long ago as 2012, the World Economic Forum came to the conclusion that data was a new class of economic asset, like currency or gold . For energy efficiency, data is the means to tap into the savings – it is the thread to sew up the hole through which waste is lost.

The internet age has brought data to everyone’s doorstep, desktop and – via smartphones – pocket too. With internet banking any account holder can get an instant breakdown of what they spend their wages on each month; comparison sites let us save ten pence a year on our phone lines with a few clicks; online shops let us spend hundreds even faster.

Despite its name and purpose, energy efficiency was not traditionally very efficient. Replacing all the light bulbs or toilet flushes was a blanket approach that was certain to achieve some savings, but did not target its efforts or costs compared against the benefits.

This is where data is the key, and where the idea of intelligent efficiency shines: with an accurate picture of where the greatest inefficiencies are, or where the easiest ‘wins’ can be found, efficiency-improving measures can be accurately focused to achieve the greatest returns on investment. With the technology now available to easily gather data on anything, anywhere, it is possible to see exactly how to most efficiently implement efficiency measures.

What is needed, then, is to find the easiest way of gathering the necessary data to make intelligent efficiency a practical, affordable reality. In the past, a similar ‘blanket’ approach was often used with data gathering technology – a large off-the-shelf or badly-tailored system would be offered or specified that would get the job done, but required a disproportionate investment of time, effort and often disruption to normal business operations.

A large up-front cost with obvious inefficiencies built in, and the common prospect of extra expenses for ‘customisation’ to come, has proven a quick way to have many an efficiency project die on the drawing board. When a substantial proportion of that cost is for ancillary aspects such as wiring and installation, it is often even harder to justify.

Modern technology and innovative thinking have, however, led to the development of far more flexible propositions. Advances in battery technology allow stand-alone devices to run for months or years without requiring any sort of ‘hard’ installation, and wireless technologies now allow stable, remote data transfer via several communication pathways.

Network solutions can be efficiently scaled almost infinitely, from a single data source to thousands of monitoring streams. With UHF/VHF radio, GSM/GPRS, SMS, Wi-Fi, Ethernet and PSTN working in conjunction, a modular system can be perfectly tailored to suit any installation environment for the most efficient combination of initial and ongoing cost.

To put these principles into context: using the right equipment, tiny, battery powered sensors can be easily installed to monitor everything from electricity, gas and water meters to heat, humidity and CO2 levels in a single room. Using the right choice of telecommunication format, this data can be gathered instantly, wirelessly, and seamlessly, then viewed and analysed on a computer or smartphone screen anywhere in the world.

For example, a common set up uses UHF/VHF transmitters on local sensors within a building , which transmit their data at no ongoing cost to an on-site, centrally-located ‘data concentrator’. This collects all the local information and sends it on as a condensed packet to a secure web server via landline for minimal data transfer costs. This not only saves on the ongoing expenditure, but also massively reduces the amount of wiring necessary to monitor potentially hundreds of points. Such a setup could also incorporate extra sensors using GPRS for outlying areas beyond the range of radio, seamlessly integrating their readings into the data stream.

Once safely on a secure web server, users and software packages can utilise historical data, calculated projections and correlated comparisons to see, immediately, where the biggest, fastest and most effective efficiency savings can be made. All this is possible without any great cost of setting up the data-gathering infrastructure, thanks to advanced wireless communications and modern battery technology.

This means that anyone, anywhere – from a single business premises to a national utility supplier – can gather and make use of the data they need, when, where and how it suits them. Flexibility, adaptability and modularity are the keys to the future of intelligent efficiency; they allow the principles to be put into practice in the most efficient way possible.
