Pasture growth rates
Pasture growth rate is the daily growth in kilograms of green dry matter of pasture per hectare (kg DM/ha/day). Pasture growth rate information can assist farmers with management decisions such as grazing rotations, feed budgeting and fertiliser application. Satellite technology provides farmers with an accurate measure of feed on offer and pasture growth rates.
Estimating pasture growth is a key component of all feed budgets. The pasture growth rate is driven by a range of factors and can be highly variable. The major determinants of pasture growth rates are:
- soil fertility
- soil type
- pasture species
- plant density.

Pastures from Space
Weekly pasture growth rates are available on a shire basis from the Pastures from Space website. The program provides estimates of pasture production during the growing season by means of remote sensing. Satellite data is used to accurately and quantitatively estimate pasture biomass or FOO and is also combined with climate and soil data, to produce pasture growth rate estimates.
This map can be scaled down to show variation across local areas.
This information can then be used for creating simple feed budgets.
