Liquid Fertilizer Rates
For dry fertilizer rate, see page 28.
Liquid fertilizer rates apply only to some single-hopper
models of NTA607, NTA607HD, NTA2007 and
NTA2007HD. The drill must be equipped with optional
tanks and liquid fertilizer pump.
Note: Great Plains recommends checking with your local
Agronomist as soil conditions vary. Soil conditions
in your area may need lesser or more amounts of
fertilizer than represented in these tables.
For in-furrow applications, do not exceed
112 litres/ha (12 gallons/ac) in any case.
Liquid Fertilizer Rate Setting Steps
1. Determine application rate desired.
2. Determine sprocket paring and pump adjuster
setting required to provide that rate. Use any of the
following resources:
• use the web calculator on the CDS-John Blue web
site www.cds-johnblue.com/flow-rate-calculator.shtml
The table on page 34 provides data required.
• use the CDS-John Blue 115797-01 (115698-91)
slide chart provided with the pump. Use the
sprocket ratios and loaded radius shown in the
tables on page 36. Some of the values in these
tables have been adjusted to ease use of the slide
chart.
• use the pre-computed tables on page 37
