Precision farming facilitates an all-time and all-over exact cultivation of small sites independent from the individual person in charge. Over-fertilization can be reduced to a minimum. Yield reserves become visible and can be utilized precisely. The technology can contribute considerably to environmental protection.

A comprehensive quantitative proof for this procedure's positive environmental influence is not available yet. One expects an environmental relief from hazardous materials as well as from other disturbances if all resources are applied as exactly as possible. If particular sites are cultivated by using their given potential as deciding factor, a high efficiency of energetic and material resources can be achieved.

The supplies of nutrients e.g. is geared to the expected yield and the resulting withdrawal. A considerable nutrient surplus and thus a threat to ground water might be avoided on such sites. Regarding their intensity and their selection of substances the regulation of weeds and pesticides can be geared to the specific need. At least quantity reductions of substances and pesticides are to expect.

The specific heterogeneity of the small agricultural sites are of central importance for biodiversity and the range of biotopes. An increasing levelling of agricultural sites regarding humidity, nutrients etc. is one of the strongest threats to biodiversity. A better consideration of this heterogeneity by means of "precision farming" is possible, positive effects for biodiversity are to expect.
