The irisTECH project is an effort to develop an innovative, easy-to-use and low-cost variable granular fertilizer application system for linear crops. The system’s operation is based on the following:

• A hyperspectral sensor combined with an intelligent artificial intelligence system
• An accessory linear fertilizer spreader with microcontrollers in the furrow system and a high-precision geographic positioning system (GNSS)

With the combined operation of all these subsystems, the identification of fertilization needs and the application of granular fertilizers is done in real time with personalized doses.

The integrated irisTECH system was implemented by following the following steps:

Creation of Machine Learning Algorithms for the accurate, effective and efficient estimation of soil parameters. – Development of data visualization and storage software. – Design and development of an information system based on cloud technologies. – Development of a hyperspectral system for its adaptation to an agricultural tractor. – Construction of the variable fertilization fertilizer distributor accessory. – Recording of the current state of the plant using the hyperspectral sensor. – Processing of data on an “onboard” graphics card. – Sending the information to the cloud. – Production of spatial information and quantification of soil fertilization needs. – Activation of a fertilizer quantity measuring mechanism by the controller. – Visualization and direct application of fertilizer in real time.
