Soil Salinity Differences in Alfalfa
The seven color image above shows a classified aerial image of an
alfalfa field in California. The grower was aware that some areas
in this field had a salinity problem. None of the soil sampling
methods currently used have dealt with the problem satisfactory.
However, an InTime scout image, based on the foliage differences
in the field and 2 or 3 soil samples, revealed the areas where
salt concentrations negatively influenced crop performance.
