Improved Nutrient Availability

Analysis (5-15-5)

What Is It?

  • TPA stands for Thermo Poly Aspartate.
  • Highly polymerized and negatively charged beta protein.
  • Biodegradable and lasts 120 days in the soil.
  • The product is available in 10L jugs, 450L and 1000L IBC’s.
  • Also available with PGRs.

When & Why Use It?

  • Used in starter fertilizer to reduce the binding of phosphorus with Ca2+, Fe3+ or Al3+.
  • Applied in alkaline soils with high content of Ca2+ and in acidic soil with high levels of Fe3+ or Al3+.
  • By reducing the tie-up, TPA increases the availability of nutrients.

What To Expect?

  • Improved root development and growth.
  • Better nutrient availability and uptake visible in tissue tests.
  • 20-25% better utilization of phosphorus and potassium.

Application Guidelines

  • Apply 0.77- 1.55 oz per 1000 sq feet.
  • TPA can be injected into the irrigation water. (micro jet or drip).
  • TPA may be used to reduce corrosion in liquid fertilizer tanks.
  • It can be applied in combination with a foliar fertilizer program.
  • TPA is for use on a variety of crops,
  • including turf.
  • Can be combined with other fertilizer mixes and pesticides.
  • A jar test is recommended especially if the desired combination has not been previously used.
