Abstract

The present invention relates to an improved pasture meter (1) which is adapted to indicate the amount of vegetative material (3) in a region. The pasture meter (1) includes a transmitter (5a, 5b) adapted to transmit a sound burst towards vegetation (3) in the region and a receiver (6a, 6b) adapted to detect at least one echo of a sound burst reflected from the region. The meter (1) also includes a processing means (7) adapted to receive at least one output signal from the receiver (61, 6b), this output signal being representative of an echo or echoes detected by the receiver (6a, 6b) in response to the transmission of a sound burst. This processing means (7) is adapted to determine the vegetation (3) location information and ground (4) location information from at least one echo of at least one transmitted sound burst. This vegetation (3) location and ground (4) location information is used by the processing means (7) to indicate the amount of vegetative material (3) in the region.
