Soil Test Values (ppm)
To evaluate in-furrow sulfur fertilizer options for corn.
With the release of our newest product Kalibrate in early 2014, deciding which potassium source to use has been a common question. One difference between Sure-K and Kalibrate is the added 6% sulfur that is part of Kalibrate. When working with soils that are low in sulfur you have two options: use of Sure-K with eNhance or Kalibrate. Both programs will provide an adequate source of the required sulfur and potassium needed for a high yielding corn crop. This experiment compared 7 gal/A of Sure-K alone, 7 gal/A Sure-K + 2 qt/A eNhance and 7 gal/A Kalibrate, which contains 6% sulfur. All fertilizer programs also contained 3 gal/A Pro-Germinator and 2 qt/A Micro 500 applied in-furrow with tubes. All treatments were sidedressed with 52 gal/A High NRG-N. Yields appear on the chart below.
- The addition of 2 qt of eNhance to an in-furrow application of Sure-K increased corn yield by nearly 3 bushels per
- Highest yield was achieved with an in-furrow application of Kalibrate, yielding 2.6 bushels per acre higher than
the combination of Sure-K and eNhance.
- In-furrow applications of eNhance are seed safe on corn up to 3 qt/A.
