Dev of irrigation advancing system in soil-based greenhouse using 3d sensing,evapotranspiration monitoring model

We intend to increase the water saving effect and product competitiveness by introducing the optimal irrigation system technology based on the evapotranspiration monitoring model in the huge tomato growing area in the southern part of spain where the climate is good but suffer from the water

At present the farmer has a wide range of different devices to facilitate the management of the crop, however much of these tools are only directed to know and manage the climate, without taking into account the real needs of the crop. These systems usually make decisions based on reference values established by local experience, without having access to the actual information on the physiological state of the crop and, therefore, do not get the most out of each crop. In this project, new advances in ICTs and plant physiology will be used to achieve optimum crop management. The OBJECTIVE of ET-3D project is to get to know the water needs of greenhouse horticultural crops, by obtaining a EVAPOTRANSPIRATION MODEL THAT BEST DESCRIBES THE PROCESS OF TRANSPIRATION, that will be fed by a 3D MAPPING SYSTEM of the crop variables (mainly climatic parameters but also physiological data, i.e. foliar area). This knowledge will provide the farmer with useful information on the water status of their crop, and perform better agronomic management, optimizing the use of resources, reducing costs and maximizing productivity. To implement this, it is necessary to develop the following agronomic tools: - Programming of an intelligent algorithm for the calculation of transpiration, based on the physiological characteristics of each variety. The implementation of a mathematically complex algorithm is not viable for any automaton currently existing in the agricultural sector. Therefore, it is necessary to design a computer platform that allows a greater processing of calculation, in order to provide the farmer with a tool capable of managing irrigation based on a model of climatic and physiological characterization of the crop. - Automatic data collection system, to provide the transpiration model with the climatic and physiological inputs needed to run the algorithm and obtain the amount of water transpired. To know the real state of the crop, the whole crop will be mapped in three dimensions, and the variables measured will be known at each moment through periodic data collection. - IT platform to be able to exploit the information obtained by the automatic data collection system, by developing a cloud where the algorithm of transpiration will be integrated, allowing to obtain a value which will determine if irrigation must be activated. The platform will have the capacity to act on irrigation actuators and notify the farmer. To achieve the aforementioned developments, an international multidisciplinary consortium between South Korea and Spain involving all the expertise areas envisaged within the project has been formed. The ET-3D project will be led by the South Korean co. NARETRENDS, in charge of creating the computer platform for irrigation management, in cooperation with the Spanish co. NAZARIES, responsible for the development of the necessary technology for the mapping of the climatic and physiological data for the algorithm. Moreover, the two companies will be technologically supported by the South Korean Technological Centre KIST, that will produce the transpiration algorithm, the University of Grenade, that will collaborate for the development of the interpolation model for massive data collection, and the Spanish Technological Centre TECNOVA, that will make the final adjustments in real farming conditions in a tomato greenhouse field. The objectives and activities proposed in the project arise from the concerns raised by the members of the consortium and are representative of the real difficulties present in the fruit and vegetable production sector, providing a totally innovative solution to the problem of water scarcity and productivity of agriculture companies.
