DRILL DESIGN COMPARISONS

Both fields were planted the same day, with the same seed lot, at the same seeding rate. Both fields had had the same cropping history for 5 years, and the prior year's wheat crop and stubble were very similar.

Wheat planted with a so-called no-till drill (actually just the old packer-wheel design with heavier down-pressure springs, but several companies sell these as 'no-till' drills). Note the substantial soil disturbance and stubble being buried. Stand was 870,000 plants/a.

This was taken just a couple hundred feet from the photos to the left. However, this field was planted with a JD 1560, outfitted with 90-series boots, SDX firming wheels, and spoked closing wheels. Extremely low soil disturbance, and all the stubble is retained. Stand was 1,240,000 plants/a.
