Getting started with FarmLab - the basics:
Draw out your paddock boundaries and select your ‘peak biomass’ month.
Select ‘Farm Survey’ to bring in data against your paddocks.
Identify which datasets might be useful in zoning (see the below walkthrough ‘Getting the most out of your farm survey’ for more details on each dataset).
Select the zoning button and choose the number of zones required, whether you want sample points identified over the zones, and the type of sampling required.
Toggle the zones on to view suggested soil management zones across the farm. Repeat step 4 to reprocess if required.
2. Getting the most out of your farm survey:
Average NDVI provides an average over 7 years of your plant biomass, for the month selected against that paddock. The colour gradient can be compared to other paddocks across the farm.
Normalised NDVI provides a view of the NDVI across each paddock by rescaling the lowest point in the paddock to 0 and the highest point to 1. The resulting colours help indicate plant biomass across the paddock.
U-Gamma is a 90m resolution map measuring Uranium gamma rays across the area. It can be used to identify granite outcrops and soil properties in specific regions (red = finer soil, blue = more rock).
K-Gamma is a 90m resolution map showing Potassium gamma rays across an area. It can be used to identiy clay content across a farm (red = high clay, blue = low).
Elevation is a 30m resolution map showing elevation across an area. High elevation is represented by the blue end of the scale, low is represented by the red.
