1. A method implemented in a computer program to provide a map of site-specific amounts of a soil nutrient to be applied in fertilizer to an agricultural field divided into sites, the method comprising:

  • calculating for the field, from a map of site-specific field characteristic data for the field, a map for the field of site-specific amounts of the soil nutrient needed to produce at each site a maximum possible crop yield; and

    subtracting, from the site-specific soil nutrient amounts for maximum yield for the field, site-specific measures of the soil nutrient existing in the field, thereby producing a map of site-specific amounts of the soil nutrient to be applied in fertilizer to the field.
