interview with Tania Georgiopoulou<\/em><\/strong><\/div>\n

How was your operational group created and which members does it consist of? \u00a0<\/em><\/strong><\/h3>\n

The purpose of Measure 16 is\u00a0cooperation<\/strong>. The goal of Sub-measure 16.1-16.5, in which we are participating, is to enhance environmental protection and adaptation to climate change.<\/strong>
\nThe measure supports the development of partnerships aimed at linking research and production, through the pilot implementation of projects by Operational Groups. So, in order to link research to production and actively contribute to the goal of environmental protection, we collaborated with ELGO-DIMITRA\u2019s Agricultural Research Institute in Larissa, \u2018GAIA EPICHEIREIN\u2019, an agricultural sector consulting company that specialises in, among other things, knowledge promotion and dissemination in the rural world, \u2018PRO DEPOT\u2019, a technology company that can support us with the very sophisticated remote sensing systems and, lastly, the \u2018Thesgi\u2019 Agricultural Cooperative in Larissa, which will translate the results of the project into practice on the field.<\/p>\n

More specifically, our business plan is to improve nitrogen use efficiency<\/strong> through an integrated variable nitrogen supply system.<\/p>\n

How did the idea for the creation of a comprehensive variable nitrogen supply system begin?\u00a0<\/em><\/strong><\/h3>\n

Dr Stamatis Stamatiadis, Director of Soil Ecology Laboratory, \u2018Gaia\u2019 Centre, Goulandris Natural History Museum<\/figcaption><\/figure>\n

This has been a research effort many years in the making. In the 1990s, we started by researching soil quality using various measurement indicators to evaluate soil quality and, consequently, crop health. Through a partnership with University of Nebraska, US, we combined technology with these metrics. In other words, we saw that remote sensing enables us to measure certain soil and plant properties remotely.<\/p>\n

This has huge advantages, and I\u2019ll explain why. Normally, to measure the quality of the soil, we need to use samplers, take samples, bring them to the laboratory, and analyse them. The same holds true for plants.<\/p>\n

On the other hand, through remote sensing we can measure many properties accurately at a distance. This is done by evaluating the wavelengths of light we get from the sensors. Besides reducing the cost of the process, we can have accurate spatial distribution of the properties, per metre of soil, which could not be done using conventional methods. Practically, how many samples can you analyse, if you have large areas?<\/p>\n

What is the originality and innovation introduced by your operational plan?\u00a0<\/em><\/strong><\/h3>\n

By securing all the information provided by a sensor about the nitrogen content in the plant, for example, which, however, changes spatially, you might be able to develop algorithms per metre related to the needs of the plant and translate that information into fertiliser doses.<\/p>\n

Thus, the spreader on the tractor is able to drop the necessary dose and all this, namely, collection, processing, transmission of the information, and its translation, must be done very quickly. The sensors, the computer system, the electronics, and the controllers, the fertiliser, and the spreader, all in sequence, must work in fractions of a second, while the tractor moves accurately. In our system, this accuracy, I would say, is unique, internationally, and the nitrogen doses change every metre.<\/p>\n

What does this mean for farmers and the environment?\u00a0<\/em><\/strong><\/h3>\n

Doses of nitrogen that are equal to the doses spread by the farmer are only required in small portions of the field. Throughout the rest of the holding they are much smaller, as the system realises that it does not take that large a dose for the crop to reach cost-optimal yield.\u00a0Measurements so far indicate that we may have a 20%-30% reduction in the total amount of fertiliser used by the farmer.<\/strong><\/p>\n

At the same time, we have major environmental benefits<\/strong> that are not unrelated to financial benefits. Indicatively, to clean up groundwater or surface water due to overfertilisation, you need huge amounts of capital. Furthermore, producers are also subsidised when they use less fertiliser, due to the losses this represents for their production. However, with this system, they will have no losses.<\/p>\n
