1 AgTM 405

2 Correlation of Yield Maps with Infrared Photography AgTM 405 Precision Farming Unit

3 The Advantages of Infrared Photography Correlated to Yield Maps Shows potential yield reduction due to irrigation, soil type or fertility problems Helps in diagnosing combine monitoring errors that show up on yield maps Low cost - less than $.50 per acre

4 Madison Farms

5 3rd generation farm since ,000 acre farm Crops grown include: Alfalfa, Canola, Corn, Buckwheat, Wheat, Potatoes, & Peas 6,479 irrigated acres Desert acres applied with bio-solids from Portland metro areas Employs people

6 Circle #17

7 Early Season Infrared - C17 Picture taken on August 11, 1997

8 Early Season Infrared - C17 Small future yield changes starting to show up

9 Early Season Infrared - C17 Infrared with yield contour lines overlaid

10 Mid-Season Infrared - C17 Picture taken on August 23, 1997 Yield changes become less noticeable

11 Late Season Infrared - C17 Picture Taken on Sept 4, 1997

12 Raw Yield Data - C17 Yield decrease in Northwest corner

13 Raw Yield Data - C17 Pivot road and planter skip

14 Raw Yield Data - C17 Yield monitor malfunction

15 Average and Contour - C17 After average and contour yield decreases show up the same as monitor malfunctions

16 Circle #3

17 Early Season Infrared - C3 Picture taken August 11, 1997 No center ring showing up

18 Infrared with Contours - C3 Infrared not showing a yield reduction on the West side

19 Late Season Infrared with Contours - C3 Picture taken September 4, 1997 Center ring showing up

20 Late Season Infrared - C3 Center ring showing up Ring caused by rotator sprinkler pressure set to high causing leaf damage to corn crop

21 Late Season Infrared with Contours - C3 Picture taken September 4, 1997 Noticeable ring showing up in the center of the circle

22 Raw Combine Data - C3 One of the two combines yield monitors was not working correctly

23 Raw Combine Data - C3 Slight center ring yield reduction showing up at harvest time

24 Raw Combine Data - C3 Slight center ring yield reduction showing up at harvest time.

25 Average and Contour - C3 Assumed low yield on West side No center ring showing up

26 Circle # 53

27 Infrared - C53 Sand ridge shows up in the infrared

28 Infrared - C53 Outer edge of the circle shows up in the infrared

29 Infrared with Contour Lines C53 Yield contour lines show the sandy ridge and the reduction in yield

30 Raw Data - C53 The sandy ridge and the outer edge both show a yield reduction

31 Average and Contour - C53 Sand ridge shows yield reduction

32 Average and Contour - C53 Outer ring of the circle shows yield reduction

33 Circle #55

34 Infrared - C55 Infrared shows the future area of low yields located on the sandy ridge

35 Infrared - C55 Infrared shows no future reduction in yield at this spot

36 Infrared with Contours - C55 Yield map contours and the infrared show the same location for yield reduction

37 Infrared with Contours - C55 Yield map contours and the infrared do not show the same location for yield reduction

38 Average and Contour - C55 Large yield reduction in the Northeast corner Center pivot reversed before the reverse stops

39 Raw Data - C55 Combine monitor error shows an assumed low yield at arrow

40 Raw Data - C55 Combine monitor shows actual low yield at arrow due to sandy ridge

41 Circle #16

42 Corn Yield - C16

43 The Question is What causes the low yield spot?

44 Nitrogen - C16 Sample date 2/12/1997 Red area 29 lbs/acre Yellow area 85 lbs/acre Green area 141 lbs/acre

45 Potassium - C16 Red area 368 lbs/acre Yellow area 501 lbs/acre Green area 634 lbs/acre

46 Ph. - C16 Red area 6.8 p.h. level Yellow area 7.45 p.h. level Green area 8.09 p.h. level

47 Phosphorus - C16 Red area 33 lbs/acre Yellow area 51 lbs/acre Green area 69 lbs/acre

48 Iron - C16 Red area 5 lbs/acre Yellow area 12 lbs/acre Green area 19.9 lbs/acre

49 Magnesium - C16 Red area 3 lbs/acre Yellow area 6.5 lbs/acre Green area 9.9 lbs/acre

50 Corn Yield - C16 Rocky Out-Cropping

51 Circle #12

52 Raw Combine Yield Data on Canola - C12 Lower yield shows up in the draw of the canyon

53 Average and Contour Canola C12

54 Circle #21

55 Raw Combine Data - C21 Lower yield shows up across the center of the circle

56 Average and Contour - C21

57 Potassium - C21

58 Nitrogen - C21

59 Phosphorus - C21

60 Sulfur - C21

61 Summarizing the Advantages of Infrared Photography Shows potential yield reduction due to irrigation, soil type or fertility problems Helps in diagnosing combine monitoring errors that show up on yield maps Low cost - less than $.50 per acre
