Abstract
A composite granular mixture of source materials, providing an NPK Fertilizer content of desired value, say 16-8-8, and a plastic binder composed of granular uncured urea-formaldehyde resin are compressed into a briquette of good 'green strength' and then resinously bonded into a drivable spike by curing the resin either at room temperature or at a suitably elevated temperature. The resulting plant food spike, when driven into the ground, functions to fertilize the immediately surrounding area at a slow even rate.
