Figure 3. Moldboard plowing used to thoroughly
mix the soil in the plow layer. Current tillage
practices including chiseling allow nutrients to
become highly concentrated in the surface soil.
The result is that cores must be collected to a
consistent depth or soil testing results will be
inconsistent as shown in Table 1.

Figure 5. Farm Management Scene This image
provides a variety of patterns such as harvesting
in progress (upper left), field not harvested
(upper center and lower right), fields that have
been harvested (upper right and west side), and
fields harvest and fall tillage has begun (lower
center). Unusual shaped areas within a field are
locations where the crop has been drown out
during early spring rains.
