Variable rate lime locations

To investigate the impact of variable rate lime applications on dry matter production and yields after assessment with PA technologies.

Key messages

NDVI satellite imagery was collected to establish dry matter production difference in 2011. The crop was sown as brown manure peas and therefore there were no yield results. Yield data will be collected in 2012 as part of the trial program.
