Starter P

Maximizing Phosphorus Use Efficiency


What is It?

  • Starter fertilizer for in-furrow.
  • High Phosphorus content.
  • Formulated with 70% Ortho- (readily available form) and 30% Poly-phosphate (converts slowly as soil warms up).
  • Low salt index.
  • No chloride.
  • Seed safe.
  • The product is available in bulk, 450L and 1000L IBC’s.

When & Why Use It?

  • When seeding into cold and wet conditions.
  • In soils with high levels of Ca2+, Fe3+ or Al3+.
  • Use to improve early-season availability and uptake of Phosphorus.
  • Use to reduce phosphorus tie-up by of Ca2+, Fe3+ or Al3+.
  • Use to supplement a well-balanced soil fertility program.

What to Expect?

  • Improved root and shoot development and crop establishment.
  • Strong advantage of the crop over the weeds.
  • Enhanced tolerance to early season environmental stress.
  • Less signs of phosphorus deficiency on the seedlings (purpling).

Size Options



Application Guidelines

  • 3-5 US gal/ac in-furrow.
  • Can be combined with other fertilizer mixes (i.e., UAN, ATS, KTS, KOH, …).
  • Starter P can be used with OMEX EDTAchelated micronutrients as required.
