Tool 8.1 Daily pasture growth estimates

This tool allows you to determine your average pasture supply, and likely variability, based on data collected in trials across southern Australia.

The mid-monthly estimates of pasture growth rates (kg DM/ha/day) following are for average seasonal conditions for a range of localities and regions across the high rainfall and wheat–sheep zones of Australia. They are from state PROGRAZE® manuals, available from your State Department of Agriculture/Primary Industries, and based on a combination of research results, growth predictions and practical experience. Although there is a large variation in rainfall pattern and feed supply within any year, when put together these monthly values reflect pasture growth in a ‘typical’ year for the locality or region without reference to growth in the previous month.

These estimates assist with calculations for short to medium term decision making in sheep enterprises and assist with the calculations in feed budgets.

Assumptions

The following assumptions are made for the pasture growth information unless otherwise stated in the values for a particular region:

  • Pastures are of moderate to high density
  • Pastures or pasture mixes with a good balance of legumes, grown on suitable soils 
  • Soil has good moisture holding capacity, such as a clay loam 
  • Pasture is maintained in an active growth phase during the growing season 
  • Pastures are well managed and fertilised to avoid nutrient deficiencies 
  • Estimates are the average for each month. 

The following variables need to be considered and adjusted against the expected local, district or regional patterns, and practical experience:

  • Climate (rainfall and temperature)
  • Soil type and variability
  • Pasture species
  • Fertiliser (nutrient) requirements
  • Grazing management.

Source: Information was originally compiled for MLA’s More Beef from Pastures manual and the PROGRAZE® manuals, developed cooperatively with the state agriculture or primary industries departments of NSW, Victoria, Tasmania, SA and WA.

 

New South Wales – pasture growth rate patterns

  • Any pasture with sub clover is assumed to have fertiliser applied yearly
  • Grass only pastures have no fertiliser
  • Growth rates are for set stocked paddocks
