Ashburn, GA, (very close to Heaven!) | martin - 11/14/2007 07:56 Thanks for posting your pic, Carl. A couple of questions: 1) you use your Dell Axim for the Sitemate. What are you using for your GPS? (If it is in the pic, I don't recognize it.) Garmin GPS18PC, the "hockey puck" on top of the battery box. 2) Are you sampling by grids? or by zones? or ????? I do very little grid work, but a lot of zones. 3) What method do you use to determine the size of the area to be included in each sample? We use B&W Terra Server Imagery, MrSid Imagery, soil maps, yield maps, scouting experience, grower experience, and sometimes just divide fields into "equal" slices, or zones. I have a couple or three different programs "for sale", but commonly sample 15 to 25 acres at a time, and we try to fertilize and lime 25 to 40 acres, minimum, at a time. It is not that uncommon for there to be several thirty acre samples in fields that are performing with satisfactory uniformity, and some six or eight acre samples mixed in. These sandy coastal plain soils are a trip to work with, and while they don't hold nutrients well, they are "easier" to fix, as sandy soils really respond to good management.
