Systems and methods suitable for growing, identifying, and tracking plugs and plants using radio-frequency identification (RFID) devices, as well as methods for making such systems. Such a method includes providing a biodegradable pot assembly and a non-biodegradable RFID module. The pot assembly has an assembly basewall and assembly sidewalls contiguous with the assembly basewall to define a cavity within the pot assembly. The RFID module is embedded within the assembly basewall, has openings therethrough, and comprises an RFID device configured to communicate with an RFID reader and store information identifying the pot assembly. The roots of a seedling grown in a growing medium within the pot assembly grow through and entangle the RFID module. Data is stored on the RFID device to identify the seedling, and an RFID reader is used to communicate with the RFID device to receive the data from the RFID device and identify the seedling.
