Salinity Mapping for Precision Variable Rate Fertilizer Application

The incidence of salinity affected areas in irrigated fields results in restricted crop growth in the saline areas. If fertilizer applications are a constant rate blanket application over the field, the saline affected areas receive a greater rate of nutrients than the crop can use. This can lead to a build up of excess nutrients, especially N and P.
