The target of 3D-Mosaic is to support the precision management of orchards by means of a concept for a decision support system (DSS) aiming to optimise efficiency of inputs, including water, and to diminish the environmental footprint of fruit production. The concept has been demonstrated with stakeholders for a spatially resolved approach in orchards bringing together robotics, sensors, geo statistics, plant physiologists, and horticulturists. 3DMOSAIC cross-fertilised the work on precise irrigation, capturing: (i) robotic and sensor groups; and, (ii) plant physiologists and application groups. It opened minds for precision horticulture in the scientific community, as well as in practice when integrating companies in the last phase of the project. The enthusiastic and critical discussions with the often-synergistic technical and social background certainly had a high impact on future research projects. The integration of companies from the beginning of the project resulted in new applications of existing sensors (DAmeter) and development of new sensors (time-resolved and frequency-based sensors). The effects may last, since senior scientists, postdocs, and several young researchers in different stages of their careers participated in the project. Finally, a comment from the external project advisor: “The level of enthusiasm, of cross-disciplinary conversations and comprehension between the participants was infectious”.
