Abstract

Utilizing adequate decision rules is the basis for a successful and sustainable agriculture. In the case of Precision Farming, these rules have to be applied to each sub-field, in which they determine the actions to be taken. The economic potential of Precision Farming increases the better the quality of the decision rules becomes. This paper presents the results of nine different field trials within three years where three different Precision Farming fertilization strategies are compared with uniform field treatment. The three strategies are a mapping approach, a sensor approach and an approach based on an artificial neuronal network. Based on the field trial results, the economic potential of site-specific N-fertilization is evaluated. The most successful fertilization approach is a method of site-specific nitrogen fertilization which automatically generates decision rules based on yield-predicting artificial neuronal networks. It is the approach which processes the most information for deducing decision rules.
