If your field only appears brown on the map, you've probably selected the optimized map as the biomass layer. This map uses a color scale from brown to purple to represent variability within the field.

What brown means

Brown colors represent low or no growth in the field. Each shade of brown represents a different range of biomass levels. If your entire field falls within the same biomass range, it will appear as a single shade of brown. However, brown doesn't mean no growth – it still indicates biomass presence at low levels.

Why it happens

Early growth stage

If your crops are in the early growth stages, such as cereals at the first to second leaf stage, they have very low ground cover per square foot. As a result, nitrogen uptake is minimal, leading to low biomass levels. On the optimized biomass map, this is visualized as brown shades.

Spring growth conditions

In spring, crops typically have 60-80 % ground cover, with an estimated nitrogen uptake of 18-31 lbs N/ac. During this phase, the map often displays shades of brown, reflecting low but present growth activity. This is normal as the crops are still developing.
