Figure 8-1. CS616 and CS625 linear and quadratic calibrations
derived from loam soil
Figure
8-2
compares the CS616 response in the Figure
8-1
loam soil to a
higher density sandy clay loam for two different electrical conductivities.
The bulk density for both sandy clay loam soils is 1.6 g cm
–3
. The
electrical conductivity at saturation for the sandy clay loam labelled
compacted soil
is 0.4 dS m
–1
. The
compacted soil, high EC
had an
electrical conductivity at saturation of 0.75 dS m
–1
. The CS625 response is
similar.
