ABSTRACT:
Conifer forests are fertilized with aqueous solutions of nitrogen compounds containing in excess of 15 weight percent equivalent nitrogen by foliar application at solution temperatures above 70.degree. F. and above the prevailing ambient temperature. The solutions have compositions and concentrations such that they are stable at the elevated solution temperature but become over saturated at ambient temperature, thereby precipitating a substantial part, i.e., at least 10 percent of the nitrogen compounds on the conifer foliage.
