Soil Testing,

duration 01:47
Soil samples are taken at various locations within a field. The samples are then sent to a lab, where PH levels and nutrient content are measured to determine how much and what type of fertilizer is needed on that particular field. Global Positioning System (GPS) technology is now being used in addition to traditional methods of charting locations within a field. As an example, using GPS allows fertilizer application equipment to be set so that fertilizer application rates are automatically adjusted, based on the earlier soil samples taken from the same field.
