- Predict temperature, vapor pressure and CO2 concentration.
- Characterization of the singular climate conditioning elements.
- Combine with a growth model of the main horticultural varieties.
Specific objectives of the I-Grow project
Study and development of a climate model for protected systems. To simulate the indoor environment according to the greenhouse configurations selected by the user and control strategies under any climatic situation. The rationale for this objective, is based on the success of commercial greenhouse operations begins with proper site location selection and an appropriate greenhouse design configuration that meets crop needs and overcomes climatic conditions. Having a tool to evaluate various greenhouse design alternatives and different climatic conditions will improve the decision making process for proper greenhouse design and optimal location. Climate models developed to date have focused on a single location and a limited and specific set of climate building and modifying elements (Rodriguez, 2015). Phenotypic characterization of the main horticultural varieties of economic interest By obtaining the variables of the Farquhar photosynthesis equation. The justification is based on the fact that obtaining a specific growth model for each variety, which defines the characteristics of the crop, at a time when there is a constant renewal of the plant material offered, could be of interest for a better agronomic management and would improve the decision making process to direct the crop towards a high productivity model. Identify the response curves of the different selected varieties to different external conditions. Currently there are production or photosynthesis models, however models to simulate various plant physiology processes, which are directly related to the productive yield of the crop, such as models of flower set, floral abortion or physiopathologies such as blossom-end rot (poor calcium assimilation), are not at the same level of development (Marcelis et al., 1998; Heuvelink et al,. 2003; Rodriguez, 2015). Therefore, in order to identify and simulate all the physiological processes that are directly related to the final crop yield, this project proposes to develop photosynthetic and agronomic response curves as a function of crop climatic variables. Development and implementation of an intelligent optimization algorithm in the cloud that manages the information obtained from the climate and crop models developed to optimize the best solution to the following options; protected system design, maximum production, costs and resource (water) optimization. The justification for the development of this algorithm is based on the fact that crop management in protected systems is based on the experience of set point values without considering the specific specifications of each commercial variety. This project proposes the possibility of taking advantage of the knowledge acquired for each variety, to condition the position of the climate actuators, and thus maximize the photosynthetic response of that variety. The implementation of an algorithm of high mathematical complexity is unfeasible for any automaton currently existing in the agricultural sector. Therefore, it is necessary to design a new cloud architecture that allows for more computational processing.Novagric’s specific objectives
