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.

To correct problems like these, a grower can write a prescription on InTime's website for a variable rate application of gypsum or any other application.
