The Pasture Growth Forecaster has been jointly funded by Beef + Lamb New Zealand and DairyNZ to help farmers increase their profitability by better feed budgeting – especially during those times of the year when pasture growth can be highly variable.
It’s available online now at pasturegrowthforecaster.co.nz.
B+LNZ chief executive Dr Scott Champion said the Pasture Growth Forecaster is a web-based tool designed specifically for NZ’s climate conditions. It considers soil types and temperature, solar radiation and how much water is available to forecast grass growth.
“While nothing about the weather is ever certain, this is a tool that pulls together the best information available to forecast grass growth so farmers can have more confidence in their decisions around supplementary feeding, grazing rotations and stocking ratios.
“Knowing when you are likely to have more or less feed than usual is going to be a key benefit of using this tool.”
There are two levels of forecast available: a free district level forecast and, for $9.95 a month, a farm level service that offers more detailed forecasting capability with greater attention to individual farm soil and water-holding capacity.
Champion said some B+LNZ and Farmax project farms had been trialling the forecaster for the past year.
“They’ve found significant benefit in being able to calculate pasture growth on their own farms, supporting timing decisions around destocking or buying in animals to use the available feed.”
The Pasture Grown Forecaster hones in on specific geographic areas broken into 44 districts divided into 5km square grids. Data from NIWA’s Virtual Climate Network Stations helps refine expected grass growth forecasts and 40 years of climate data is also applied to the calculations.
“The timing is important because farmers who start using the tool now will become familiar with it before summer and autumn – the times of the greatest grass growth variability from season to season,” Champion said.
The forecaster was developed by Rezare Systems, with Farmax running the free and paid versions of the tool’s web-based service.
