Solid dosage forms
First Claim
1. A solid dosage form comprising a compacted particulate blend consisting essentially of(a) a compression moldable finely divided homogenous particulate mixture of from about 0.05 to about 25 percent of microcrystalline cellulose having a particle size of from about 20 microns 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 about 10:
- 1 to about 1;
10;
(b) from about 16 percent to about 65 percent of an active material compatible with the particulate mixture of (a) and selected from herbicides, plant growth regulators, pesticides and any mixtures thereof; and
(c) 0 to about 20 percent of an additive selected from glidants, lubricants, dispersants, surfactants, and auxiliary disintegrants and mixtures thereof.

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 microcrystalline cellulose. The composition can be compacted to form shaped, solid dosage forms such as tablets which disintegrate rapidly in an aqueous medium.
