Average 168.1 kg/ha distribution
pattern. (Note the existing W-pattern) |
 |
Modeled 168.1 kg/ha application surface. |
 |
Actual 56.0 kg/ha application surface for multiple passes. Represents what would be spread during field operation. |
 |
Rate change application surface changing rates from 56.0 to 168.1 kg/ha. (Note the observed pattern shift during the rate change) |
 |
Modeled rate change application surface. (Rate change dynamics modeled using sigmoidal functions) |

Generation of an "As Applied" Surface |
|
 |
Prescription ma for potash. (1 acre management zones) |
 |
Resulting "As Applied" application tract generated by AgView. |
 |
Selected distribution patterns for "As Applied" map generation. Each pattern represents a defined range (low, medium or high). Each point within the AgView file contains the amount spread at the point, thereby determining which pattern to assign at the point |
 |
Example assigned polygon representing the applied material to each point. The amount of material applied in each sub-polygon based on the recorded quantity at each point times the normalized spread pattern shown above. |
 |
The polygons based on "As Applied" file. The red matrix was then overlaid and intersecting polygons summed at each point to calculate the amount of material spread at each of the red points. (Points lying outside boundary were deleted) |
 |
The resulting "As Applied" matrix overlain on the prescription map. The presence of a point shows deviation from the prescribed amount at that point. |
