MIXTURES OF FERTILISERS COVERED INDIVIDUALLY BY DIFFERENT SUBCLASSES OF CLASS

**Definition:** This place covers:

Materials affecting the growth of plants solely by supplying nutrients ordinarily required for growth or materials which are used to prevent or cure mineral deficiencies in plants as listed below:

Mixtures of fertilisers covered individually by different subclasses of class C05 , e.g., superphosphates with ammonium nitrate, Thomas phosphate with potassium compounds, alkali or ammonium orthophosphates with ammonium nitrate, ammonium nitrate with limestone or calcium carbonate, ammonium sulfate with potassium compounds or fertilisers containing plant vitamins or hormones with fertilisers containing potassium from minerals or volcanic rocks.

Mixtures of one or more fertilisers with additives not having a specifically fertilising activity, e.g., pesticides, soil conditioners, wetting agents, nitrification inhibitors or superabsorbent polymers.

Fertilisers characterised by their form, e.g., granules, spikes or tablets.

Preparation, treatment or modification of any of the materials above: e.g., by chemical means (e.g. addition of stabilisers, preservatives), physical means (e.g., irradiation, concentration, purification, separation) or combination of both chemical and physical means, with the proviso that the resultant product is proper for classification in this subclass.

Methods of preparing fertiliser mixtures of the above subclass in general.

Fertilisers in liquid form; Special formulations prepared to obtain a liquid form of the fertiliser.
