DEFINITION

Classification: 71/64.01

Forms or conditioning:

(under subclass 1) Processes not hereinabove provided for, directed to the preparation of fertilizers in commercial forms.

(1) Note. The fertilizer forms, as articles of manufacture, also belong here. Methods directed to the conditioning of fertilizer values, such as obviating hygroscopicity, granulating, or rendering a fertilizer friable (as by quenching) are also classified herein.

47, Plant Husbandry, for structures formed of or containing fertilizers, such as flower pots, stakes and mulching sheets, utilized in plant husbandry, and fertilizing cartridges adapted to be buried in the earth.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes, for processes of comminuting or granulating a liquid or molten substance are classified in

5+, even though the granulated substance is claimed as a fertilizer. Processes of granulating a mixture of reagents to give a fertilizer composition are in this class (71), in the subclass determinative of the composition.

206, Special Receptacle or Package,

524.1+, for a container with specified material for content or receptacle, particularly subclass 524.5 for a container with caustic content. 516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, for colloid systems or agents for such systems or making or stabilizing such systems or agents, especially

20+, for organic continuous liquid phase, subclasses 38+ for bituminous, coal, or Carbon suspended in aqueous continuous phase, subclasses 77+ for colloid systems of colloid-sized solid phase dispersed in aqueous continuous liquid phase; in each instance, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art.
