A pasture wedge graph or feed wedge is a farm management tool used by dairy farmers for the purposes of managing pasture.[1][2][3] It takes the form of a bar graph,[4] that shows the amount of feed available in a pasture over time, and is therefore shaped as a declining wedge.[3]
Rotational grazing systems[5] have developed on temperate pastures consisting of perennial ryegrass and white clover.[6][7] The pre-grazing pasture mass and the post-grazing residual (1500 kg/DM/ha) are critical decisions the dairy farmer has to make every day.[8][9] The development of the 'Rising Plate Meter'[10] has enabled the pre-grazing and post-grazing pasture masses to be measured.· Pasture eaten, measured as megajoules of metabolisable energy per hectare (MJME/ha) or as kilograms of dry matter (kg DM/ha), is a key driver of profit for all farm systems i.e. pasture grown x pasture utilisation.[11][12]
