Enhanced Efficiency Fertilizer

 

MacroSource is one of the largest wholesale providers of pre-treated Enhanced Efficiency Fertilizers (EEFs) in the USA.

Growers in the world face challenges each season in managing nitrogen inputs for their crops. At MacroSource, we provide retailers with pre-treated nitrogen fertilizers stabilized to reduce the grower’s risk of nitrogen loss.  Our EEFs contain the active ingredients NBPT & DCD, which are documented by university testing and defined by AAPFCO (American Association of Plant Food Control Officials) as urease and nitrification inhibitors.

Proprietary EEF Portfolio

Nitrogen fertilizers pre-treated with NBPT stabilizer, a urease inhibitor.

The NBPT found in N-Crease is a substance that inhibits hydrolytic action on urea by the urease enzyme.  When applied to soils, a urease inhibitor results in less urea nitrogen loss by ammonia volatilization (AAPFCO Official 1997.)

When unprotected urea is hydrolyzed by urease, with much of the resulting ammonium being held on soil exchange sites.  During this conversion, the pH rises and ammonia gas is produced.  The loss of ammonia, termed volatilization, can be from nil to over 50% (1).  Research suggests NBPT-treated urea can reduce ammonia loss by 50% to 90% when compared to that of untreated urea (2).

Nitrogen fertilizers pre-treated with DCD stabilizer, a nitrification inhibitor.

The DCD found in D-Crease is a substance that inhibits nitrification, the biological oxidation of ammoniacal nitrogen to nitrate nitrogen.  (AAPFCO Official 2001).  IPNI recognizes DCD as one of the commonly used and best understood nitrification inhibitors. (3)

  • The University of Illinois estimates that 4-5% of NO3-N will be lost each day the soil is saturated. (4)

  • Once NH4+ is nitrified to nitrate (NO3-), N is susceptible to loss by denitrification and leaching.  Nitrification inhibitors such as dicyandiamide (DCD)… can retard this conversion, reducing loss potential.  When properly applied, inhibitors can significantly affect crop yields. (5)

Nitrogen fertilizers pre-treated with NBPT + DCD stabilizer, for protection against all major forms of nitrogen loss.

 Now dealers can count on above and below ground nitrogen protection with one stabilized product.

  • NBPT protects against volatilization loss while the nitrogen is on the surface.

  • Once the nitrogen moves into the soil profile, DCD slows the nitrification process reducing losses to leaching and denitrification.

UAN fertilizer pre-treated with NBPT + DCD stabilizer, for protection against all major forms of nitrogen loss.

Specifically designed to be mixed with UAN solutions, Hi-Tec is the smart fertilizer option when your grower’s UAN is surface applied or lightly incorporated.  75% of the nitrogen in UAN is in the Urea or Ammonium (NH4+) form and is susceptible to loss.  Hi-Tec protects these two forms of nitrogen from undesirable loss through volatilization, leaching and denitrification.
