<p>A process for determining the health of crops in a field and treating the crops in accordance with that determination. The process first establishes, in a field in which the health of the crops is to be determined, at least one predetermined reference area of crops having a determined nutrient, e.g. nitrogen, content. Then georeferenced aerial photographs, the green plane (60) is determined. From the green plane, a relative greenness map (70) of the field based upon the nitrogen reference area is prepared. The greenness map (70) may be transmitted to a farm vehicle on the field and thereafter, the field may be selectively treated in accordance with the nutrient deficiencies detected and recorded on the greenness map.</p> |
