Slow release fertilizer composition consisting of asphalt wax binder and inert filler

Claim 2

A DENSE, SLOW RELEASE PELLETIZED FERTILIZER COMPOSITION WHICH IS SUBSTANTIALLY NON-TACKY AND CAKE-RESISTANT WHEN STORED, SAID COMPOSITION COMPRISING A MAJOR PROPORTION OF WATER-SOLUBLE INORGANIC FERTILIZER PARTICLE AND MINOR PROPORTIONS OF (A) A SUBSTANTIALLY INERT FILLER AND (B) A WATER REPELLENT HYDROCARBON BINDER; SAID PARTICLES BEING AT LEAST PARTIALLY COATED WITH A THIN FILM OF SAID BINDER; AND SAID FILLER BEING DISTRIBUTED THROUGHOUT SAID COMPOSITIION SO AS TO IMPROVE THE LEACHING RESISTANCE OF SAID COMPOSITION.

Claim 3

A PROCESS FOR MAKING A DENSE SLOW RELEASE PELLETIZED FERTILIZER COMPOSITION COMPRISING THE STEPS OF (A) INTIMATELY MIXING AT A TEMPERATURE OF ABOUT 155 TO 230*F., WATER-SOLUBLE INORGANIC FERTILIZER PARTICLES AND A A WATER REELLENT HYDROCARBON BINDER, SO AS TO SUBSTANTIALLY COAT SAID PARTICLES WITH SAID BINDER, THEREBY PRODUCING A FRIABLE, GRANULAR AND MODERATELY STICKY MIXTURE; (B) INTIMATELY MIXING THE MIXTURE OF STEP (A) WITH SUFFICIENT SUBSTANTIALLY INERT FILLER TO PRODUCE A FRIABLE, GRANULAR AND RELATIVELY DRY MIXTURE; (C) COMPRESSING SAID DRY MIXTURE OF STEP (B), UNDER RELATIVELY HIGH PRESSURE AND AT A TEMPERATURE OF ABOUT 155 TO 212*F., INTO HARD, DENSE PELLETS, THEREBY PRODUCING A NON-STICKY, NON-TACKY, FERTILIZER COMPOSITION.

Claim 4

A PROCESS FOR MAKING A DENSE SLOW RELEASE PELLETIZED FERTILIZER COMPOSITION COMPRISING THE STEPS OF (A) INTIMATELY MIXING AT A TEMPERATURE OF ABOUT 155 TO 230*F., WATER-SOLUBLE INORGANIC FERTILIZER PARTICLES AND A A WATER REELLENT HYDROCARBON BINDER, SO AS TO SUBSTANTIALLY COAT SAID PARTICLES WITH SAID BINDER, THEREBY PRODUCING A FRIABLE, GRANULAR AND MODERATELY STICKY MIXTURE; (B) INTIMATELY MIXING THE MIXTURE OF STEP (A) WITH SUFFICIENT SUBSTANTIALLY INERT FILLER TO PRODUCE A FRIABLE, GRANULAR AND RELATIVELY DRY MIXTURE; (C) COMPRESSING SAID DRY MIXTURE OF STEP (B), UNDER RELATIVELY HIGH PRESSURE AND AT A TEMPERATURE OF ABOUT 155 TO 212*F., INTO HARD, DENSE PELLETS, THEREBY PRODUCING A NON-STICKY, NON-TACKY, FERTILIZER COMPOSITION.
