Definitions

  • the present invention relates to the treatment of the soil and/or pasture, compositions for application to the soil and/or pasture, procedures for preparing such compositions, compositions thus formed, fertiliser compositions and related uses.
  • Nitrification is the process of conversion of a relatively immobile form of nitrogen (N) from an ammonium (NH + ) form into the more mobile nitrate (NO 3 " ) form.
  • N ammonium
  • NH + ammonium
  • NO 3 " more mobile nitrate
  • Nitrates, produced from the nitrification process, is subject to losses by leaching from soils and can potentially contaminate surface and ground water.
  • Nitrates can also undergo denitrif ⁇ cation in the absence of oxygen by a taxonomically diverse group of microorganisms to gaseous oxides of N (e.g. N 2 O) and nitrogen gas (N 2 ), which are commonly lost to the atmosphere. These losses of N account for inefficiencies in the use of applied N by plants, whether from N including fertilisers or urine, or both.
  • N 2 O is one of the greenhouse gases and also has a catalytic effect on the destruction of stratospheric ozone.
  • An approach previously proposed to increase plant N use efficiency and minimise potential adverse environmental effects by nitrogeneous compounds is the use of nitrification inhibitors.
  • Nitrification inhibitors are compounds that delay the microbial oxidation of NH + to NO 2 ' (the first step of the nitrification process) for a certain period by depressing the activity of Nifrosomonas bacteria in soils. The second step of nitrification it is believed normally is not influenced.
