Objective:

Comparison of different sources of planter time fertilizer to Pro-Germinator for yield effect on corn.

Each season the NCRS gets questions on how various other phosphorus containing planter time fertilizers compare to Agro-Culture Liquid Fertilizers Pro-Germinator. In most experiments at the NCRS a conventional fertilizer source is included for comparison. The data below shows three different experiments comparing Pro-Germinator to a conventional product. In each of these experiments a different outside source of phosphorus fertilizer was used. The three products compared to Pro-Germinator were: 10-34-0, Season Pass (6-18-6 w/S and Zn) and Black Label (6-20-0 w/Zn). Fertilizer rates, placement (in-furrow or 2×2) and yield results appear on the chart below.

Pro-Germinator is KINGConclusions:

  • All fertilizer sources significantly increased corn yield over the no planter fertilizer treatments.
  • Pro-Germinator yielded significantly higher than both Season Pass and Black Label. (Note: Season Pass was applied at manufacture suggested rate of 4 gal/A).
  • There was no difference in yield between programs of Pro-Germinator and 10-34-0. Potassium as Sure-K can be applied along with the Pro-Germinator, while muriate of potash is a separate application with 10-34-0.
  • As shown in past years of research, Agro-Culture Liquid Fertilizers’ Pro-Germinator yields similar to and often out performs other sources of phosphorus planter fertilizer.
