3.02 - Setting pasture targets
The following list outlines the critical pasture limits for production and environmental protection:
- To maintain maximum pasture growth, have a:
- minimum pasture mass of 1,000kg green DM/ha
- maximum pasture mass limit of 2,500kg green DM/ha, except when determining how much feed needs to be carried into a summer dry period when livestock is being carried over this period (ie breeding operations and often trading operations don’t carry stock through this period).
- To optimise pasture performance throughout the year and minimise pasture decline, have a:
- maximum total pasture mass of 1,500kg DM/ha prior to the autumn break to promote clover germination and growth and to maximise tillering of perennial grasses and to prevent aerial tillering of perennial ryegrass.
- minimum pasture mass during the growing season of around 1,000kg DM/ha for high pasture quality and yield.
- To prevent water and wind erosion and protect the resource base:
- minimum residual pasture mass of around 800kg DM/ha depending on pasture density
- depending on rainfall (pattern and intensity) and soil type, maintain at least 70% groundcover (including leaf, dead and litter material plus dung) on grazed lower to middle slopes (landclass 3) and a minimum of 100% groundcover on non-arable upper to steep slopes (land classes 4 and 5).
