Speciality fertilisers


“Group 3 fertiliser” is a natural or synthetic substance or organism/s that improve/s the growth or yield of plants or the physical, chemical or biological conditions of the soil and does not qualify for registration as a group 1 or 2 fertiliser.

This includes:

  • Biofertiliser (Fungi, Mycorrhizae, bacteria)
  • Soil enhancers (water retention)
  • Fulvic and humic acid
  • Sea weed
  • Amino Acids
  • Products of plant and animal origin (exclude bone and blood meal)
  • Fertiliser coatings
  • Plant Growth Regulators
  • Novel products

Speciality fertilisers can be applied along with irrigation water, or in a controlled-release way where a pre-plant application releases nutrients for the plant throughout the time when it is growing. Speciality fertilisers might also be applied by foliar feeding where the plant absorbs nutrients through its leaves rather than through the roots.

Owing to some promising results, this is an area that has caught the attention of role players from all corners of the market, from the agrochemical to the organic/sustainable agriculture sectors.
