Abstract. Two mail surveys were carried out in Denmark and the Eastern Corn Belt, USA in 2002.
Questionnaires were sent to 580 farmers who had used precision agriculture (PA) and 198 responses were
received. The surveys focused on the current status of use of PA in both countries, including: PA practices,
equipment and software, Internet and e-mail use, information sources for PA, satisfaction level from service
providers, data handling, interpretation, storage and ownership, value of data for decision making, changes
in management practices, desired information and services, and the next planned step in the practice of PA.
The survey results showed more similarities in practicing PA between the two countries than diﬀerences.
Time requirement and high cost of data handling were cited as the main problems. Survey respondents
found soil maps to be more valuable than yield maps in management decisions. About 80% of the
respondents would like to store the PA data themselves. The majority of the respondents indicated that they
have changed their management practices due to PA, but not substantially. Some 90% of the respondents
used the Internet and e-mail for agricultural purposes, but only a small number for PA websites.

The goal of precision agriculture (PA) is the management of crop and soil variability
to increase proﬁtability and reduce environmental impact. Within the concept of PA,
the main activities are data collection and processing and variable rate (VR) appli-
cations of inputs. The tools available consist of a wide range of techniques and
technologies from information technology, sensor and application technologies,
farm management and economics.
PA is ‘‘information intensive’’. It is important to recognize PA as a systems
approach (Blackmore, 2000) and the value of the increased information ﬂow as a
