| 1/ These estimates are revised from previous published
estimates based on updated weights from the ARMS. |
| 2/ Prior to 2002, respondents were asked if the
soil characteristics of this field had ever been geo-referenced.
Beginning in 2002, respondents were asked about geo-referencing
in the current and previous year. |
| 3/ The question was reworded in 2002 to better define
the term"remotely sensed". |
| 4/ Guidance system connected to GPS for one or more
field operations. |
