Biomass imagery

NDVI images that indicate how photosynthetic a crop is

Biomass imagery highlights areas of low and high biomass within your crop using satellite-derived NDVI (normalised difference vegetation index) images that indicate how photosynthetic a crop is.

Multiple images are available throughout the season to track crop performance.

Service use

Biomass imagery is used to produce data on:

  • Variable rate nitrogen applications
  • Variable rate plant growth regulator (PGR) applications
  • Intelligent crop walking
  • Smart tissue analysis


  • Yield increases of 3-5% using variable rate nitrogen
  • Variable rate nitrogen applications also help to reduce lodging risk

What is involved

  • Provide fields and locations for which you require maps
  • Let us know what fertiliser you are using
  • Let us know the preferred application rate
  • We’ll do the rest and provide you with all the data you need

Intelligent crop walking

View and compare NDVI images to see how crops are performing throughout the season. Images can be viewed on an app. 

Variable rate nitrogen

Variable rate nitrogen is a simple process. You enter the average rate you wish to apply to the field and enter the percentage variation from that figure you would like to use.

Our partner provides figures on the variability of your crop. You can change grid sizes to fit with equipment size and rotate grids to fit tramlines.

Variable rate nitrogen application is not designed necessarily to save money, but more to optimise fertiliser application according to crop need. The main benefit of the service is the optimal increase in yields that are achievable.
