This report describes a
on-farm corn nitrogen
research project conducted in Southeast Missouri in 1998 and 1999.
The test was an evaluation of a new type of no-till anhydrous ammonia
applicator developed by Paul Lanpher at Advance, Missouri. The
equipment helps reduce the amount of ammonia gas lost during
application on no-till fields.
Paul Lanpher is an
innovative no-till corn farmer from Advance, Missouri. In 1997,
he developed a new type of fertilizer shank (called C-Jet) that
delivers a 6-inch wide zone of anhydrous ammonia. Before using
the new shank, he had been observing large amounts of ammonia gas
being lost through the straight slot created with his conventional
anhydrous applicator. The C-Jet loosens the soil while applying
the fertilizer under the seed bed with minimal surface residue
disturbance. Because the fertilizer is distributed over a wide
area, he has been able to apply high rates of N under the row without
causing corn seedling injury.
Experiments showed that the C-Jet
shank increased corn yields numerically as compared to applying the
same rate of N with an applicator from a local farmer cooperative.
Two year results showed that corn yields with N applied in the row
middles produced 156 bushels per acre with a conventional fertilizer
straight shank. Corn yields averages 163 bushels per acre with
the same rate of N applied with the C-Jet shank in the middles.
When anhydrous was applied with the C-Jet under the row, corn yields
increased 8 bushels more per acre as compared to applying it with a
C-Jet in the middles.
Applying under the row with
the C-Jets yielded 15 more bushels per acre than with a conventional
fertilizer straight shank in the Middles.
