Solid dosage forms
First Claim
1. A compression moldable finely divided homogeneous particulate excipient blend for producing compacted solid dosage forms, consisting essentially of microcrystalline cellulose having a particle size from about 20 to about 90 microns and a nitrogen compound selected from the group consisting of urea, ammonium sulfate and ammonium phosphate, in which the weight ratio of microcrystalline cellulose to nitrogen compound is from 2:
- 1 to about 1;
3, said composition optionally containing from 0.5 to 25% by weight, based on the microcrystalline cellulose, of a suspending agent selected from water soluble hydrocolloids compatible with and effective for assisting in the hydration of microcrystalline cellulose.

Abstract
A composition for agricultural and other actives, comprising a finely-divided particulate combination of microcrystalline cellulose, at least one nitrogen compound such as urea, an ammonium sulfate or phosphate and, optionally, a suspending agent for the micro-crystalline cellulose. The composition can be compacted to form shaped, solid dosage forms such as tablets which disintegrate rapidly in an aqueous medium.
