A system for marking land (figure 5), comprising a tag (24) adapted to store a code, a planter device (10) for planting the tag at a predetermined location , and a scanner (25) for reading the code of the tag to identify the predetermined location. The tag is preferably a radio frequency microchip (2 4) adapted to store an alphanumeric code. The planter device includes a planter head (16) adapted to hold the microchip and to plant the microchip at the predetermined location. The scanner generates a scanner signal (26) to power the microchip. The powered microchip generates a microchip signal containing the code (28), and the scanner reads the microchip signal to identify the predetermined location.
