John Deere announced four new companies to its 2021 Startup Collaborator program: Nori (developing a carbon market), NVision Ag (developing nitrogen management decisions), Scanit (offering detection and classification of airborne plant pathogens) and Teleo (converting construction and mining equipment into tele-operated robots). Launched in 2019, the yearlong program enables John Deere and selected startup companies to test new technologies without a more formal business relationship, Deere said in a statement.
