DEP uses remotely sensed and other data to derive a tillage practice for each
modelled hillslope point. This practice is expressed as a code with increasing
values implying more intense tillage. Here's a brief summary of what each
code implies.

| 2 | Very high mulch |
Spring field cultivate, plant (includes fall chisel plow before corn) |
| 3 | High mulch |
Fall chisel plow, spring field cultivate, plant (includes disk before corn, disk was substituted for field cultivate for sorghum). |
| 4 | Medium mulch |

| 5 | Low mulch |
