Narrative:

Ran out of fuel returning to home base (ykn) after completing crop photo mission. Total time in the air was 6 hours 25 mins. Thought I had fuel enough for 7 hours and 15 mins. Used endurance profile chart for cessna model 172P with extended range tanks, page 5-22 cessna poh (yr 1981). This chart is for 62 useable fuel, the specific aircraft I was flying had only the 50 gal extended range tanks. I inadvertently used the wrong chart. During the descent for landing at the bloomfield airport which is unattended, I misjudged the approach altitude 'too high' and overshot the runway. As there was a cleanly mowed hayfield off the end of the runway, I landed in the field and rolled to a stop. No damage was done to aircraft or property. Aircraft was refueled and flown out of field to ykn.
