Quaterna® TerraUAB is a type of soil conditioner that allows humification of all organic forms found in soil. The rapid production of humus increases the clay-humus complexes and soil fertility. It naturally replaces P/K fertilization, lime/calcium and reduces mineral nitrogen fertilization.


Quaterna® TerraUAB recycles the mineral elements that are not absorbed by the plant. It increases the humus content in your soil and provides the nutrients necessary for the plant, when the plant needs them, to enable optimal growth and a stable yield can be achieved.

Economic & environmental benefits for agriculture and the environment :
  • Optimization of your incomes
  • Improvement of soil structure and soil fertility
  • Increase resistance to drought stress
  • Better root penetration, increased fine root growth
  • Saving of mineral fertilization, better utilization of organic fertilization
  • Optimisation of nitrogen management
  • Guaranteed improved palatability of the grass
  • Reduction of leaching losses, e.g. from nitrate
A concept of economic fertilisation in line with the environment
  • An effective response to the new agri-environmental standards
  • A reliable way to protect the environment
