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.
