Nutrient Uptake Efficiency Enhancer

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 nutrient availability.

What To Expect?

  • Improved root development and growth.
  • Better nutrient availability and uptake visible in tissue tests.
  • Increased tuber count in potatoes with an even size.
  • Improved marketable yield in potatoes.

Application Guidelines

  • Apply 1-2 L/ac of TPA with in-furrow applied liquid fertilizer.
  • 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.
