These management systems will be site specific. Generic decision support systems will be developed, but their performance on your farm will be enhanced by data from your farm. Agricultural databases take time to accumulate. For example, because of weather variability, accurate information on site specific yield potential and problems may require several seasons of data. Retesting soils at the same sites creates data on fertility trends.
History shows that most of the benefits of any new agricultural technology go to the early adaptor.
Those who lag have often been forced out of farming. Precision farming is expected to follow the same pattern. Those who begin to accumulate data and experience now will be ready to use improved precision technology as it matures. Who benefits from precision farming will be determined by how management of precision data is organized. To realize the full benefit from precision farming farmers will probably need to pool data.
