    摘要： Phenolic amides, useful as stabilizers for organic materials such as polyols and polyurethanes, possess the general formula ##STR1## wherein n is 0 to 3, R.sub.1, is alkyl of from 1 to about 6 carbon atoms, R.sub.2 is hydrogen or alkyl of from 1 to about 6 carbon atoms, R.sub.3 is hydrogen or hydrocarbyl of up to about 20 carbon atoms, optionally containing one or more heterocyclic groups, R.sub.4 is hydrocarbyl of up to about 20 carbon atoms, optionally containing one or more heterocyclic groups, or R.sub.3 and R.sub.4 together with the nitrogen atom to which they are bonded are joined together to form a heterocyclic group, optionally containing one or more additional heterocyclic atoms.

    摘要： A disk composed of rigid open cell synthetic resin foam has a recess in one face for being occupied by fertilizer. A water permeable plug of similar foam is inserted in the recess to retain the fertilizer and to serve as a wick for conducting fertilizer dissolved in water out of the recess and into the bottom hole of a plant pot standing on the disk for the fertilizer to permeate the soil in the pot. The fertilizer is preferably composed of pellets coated with water permeable resin. In use the disk is set in a reservoir and covered with water.
