Abstract
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 are taken of at least a portion of the field. From the photographs, the green plane is determined. From the green plane, a relative greenness map of the field based upon the nitrogen reference area is prepared. The greenness map 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.
