Comments: N/A

Description: The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A process for the production of a granular ammonium nitrate-ammonium phosphate fertilizer composition comprising the steps of compacting a ground, mixed blend of ammonium nitrate and
monoammonium phosphate or diammonium phosphate or a mixture thereof to produce a compacted material, breaking said compacted material produced thereby, and grinding said broken compacted material to produce said granular ammonium nitrate-ammonium phosphate composition.

2. The process of claim 1 wherein the ratio by weight of ammonium nitrate to ammonium phosphate is from about 4:1 to 1:4 and the ammonium phosphate is monoammonium phosphate.

3. The process of claim 1 wherein the ratio by weight of ammonium nitrate to ammonium phosphate is from about 4:1 to 1:4 and the ammonium phosphate is diammonium phosphate.

4. The process of claim 1 wherein the ammonium phosphate is a mixture of monoammonium phosphate and diammonium phosphate in a ratio of about 1 part to 4 parts by weight of ammonium nitrate to about 4 parts to 1 part of ammonium phosphate.
