The criterion of the heterogeneity is the upper limit of cell side length as defined in Fig.

.
The
results are from vehicle based, site-specific sensing for N with red edge inflection indices and a
vertically viewed sampling area of 1.5 m

(From Thiessen

•
the eastern, hilly, loamy region with mounds and depressions in the fields
•
the flat, sandy, central region
•
the very flat, loamy region of Fehmarn island.
From the topography of the fields, the highest heterogeneity should be expected
from the rolling, hilly fields in the eastern region and the opposite from the very flat
agricultural areas in Fehmarn. The average upper limits of cell side lengths confirm
these expectations, however, there is much overlapping of individual data.
