Using Density Meter and Fertilizer Charts

IMPORTANT: Rates shown on charts are only to be used as a guide. See RATE CHECK-METHOD ONE and RATE CHECK-METHOD TWO in Operating The Machine section for accuracy.

1. Rates are based on fertilizer having a density of 1.04 kilograms per cubic decimeter (65 pounds per cubic foot).

2. Use density meter (A) available from your dealer to determine density, or contact fertilizer dealer. Nitrogen fertilizers generally weigh less than high potash or phosphorus fertilizers. Fill meter bucket with material, tap lightly, level material across top, balance meter on knife edge and take reading.

3. Use conversion chart for other densities.

Density
kg/dm3 (lb/ft3)
Conversion Factor
0.72 (45) 1.45
0.80 (50) 1.30
0.88 (55) 1.20
0.96 (60) 1.10
1.04 (65) 1.00
1.12 (70) 0.93
1.20 (75) 0.87
1.28 (80) 0.81

 

EXAMPLE: To apply 112 kg/hectare (100 lb/acre) with a density of 0.72 kg/dm 3 (45 lb/ft 3 ) multiply 112 (100) by conversion factor-1.45.

EQUATION: 112 x 1.45 = 162 kg/hectare (100 x 1.45 = 145 lb/acre).

Locate 162 (145) in fertilizer charts for chosen row spacing and set gear case speed selectors. For this example, with 15 cm (6 in.) row spacing, set the gear case selectors in A1 and the feed shaft speed in Drive Z.
