Swath width and Navigation
Setting the swath width and navigation system is at the
discretion of the customer. A 50’-75’ (15-
23 m) swath works well in most areas. Several methods of navigation are possible: following
previous crop rows, swath guidance, or using a field navigation computer. While it is important to
map in a consistent p
attern, it isn’t absolutely critical that each pass be exactly the same distance
from the previous pass.
To help insure the quality of your data, please follow these guidelines:
1. Generate and view maps frequently, especially prior to deleting data from Instrument.
2. Listen for auditory alarm from DataLogger, indicating data collection has been interrupted.
3. View DataLogger screen or SoilViewer map frequently during data collecting; watch for:
Negative readings in the Shallow and Deep or excessive noise in the data.
EC readings should fluctuate gradually as you drive across the field, relating to
soil changes. If readings change erratically, or show values not typical of soil
conductivity in the area
—such as >100, perform tests 4 and 5 below.
In SoilViewer, watch for streaks, stripes, unnatural patterns, and missing data points.
4. Perform electrical continuity test on implement wiring:
at least once a day during mapping season
every 10 hours of mapping
after extended periods of non-use
after replacing or repairing coulter-electrode components or wiring
whenever readings are questionable
5. Perform Signal Testing Procedures #1 and #2:
at least once a day during mapping season
every 10 hours of mapping
after extended periods of non-use
whenever readings are questionable
6. Keep all electrical connections dirt and moisture-free
7. Limit speeds in rough or rocky field conditions. This will improve data quality, and will also
lengthen the service life of the implement components. NEVER EXCEED 15 M.P.H. FIELD
SPEED.
