Effect
of Starter Fertilizer in Cotton
|
The seven color image above shows a classified aerial image
of a cotton field in south Alabama. The field was planted in the
same variety. The grower started planting on the east side. At
planting he added a starter fertilizer of 25 units of nitrogen.
Approximately 3/4 into the field he doubled the amount of starter
fertilizer. The classified image shows the area where the starter
fertilizer was applied at double rate to be in classes 6 and 7
compared to the areas where the starter was applied at single
rate. This indicates that there was more vegetation in the areas
where the starter fertilizer was doubled compared to the rest of
the field. |
