Humic acid is a powerful nitrogen synergist. Nutri-Carb-N™ is based on the proven productivity of the perfect partners – urea and humic acid.

A combination of liquid organic humates and nitrogen, which effectively addresses many of the shortcomings of nitrogen in high-production agriculture.


  • Nitrogen is held in the root-zone for much longer than normal, resulting in maximum nitrogen utilisation and reduced leaching.
  • Includes a potent carbon source to prevent nitrogen-related carbon depletion.
  • Liquid humates improve soil structure, release locked up nutrients, and promote soil microorganisms.
  • The humic acid component improves the performance of all other applied fertilisers.
