We do something similar to the larger commercial farm, except without the 
GPS, etc..  We have 2 main orchards of 11,000 trees covering about 100 acres 
total which you can see at 
http://www.royaloakfarmorchard.com/pdf/upickguide.pdf.  Each 50 acre parcel 
is divided into zones for soil testing and irrigation.  We have a total of 
12 zones, each 50 acre parcel with 6 zones each.  We take soil samples from 
each zone as well as leaf samples and send them to 
http://www.algreatlakes.com/main.asp for analysis.  They give us our 
analysis by zone and we then follow their recommendations.
