Fertilizer Application Can Improve Red Pine Seed Production

Red pine (Pinus resinosa Ait.) is one of the most important reforestation species in the eastern part of temperate North America. Although planted extensively in both the United States and Canada, this species does not have frequent seed crops, and seed is often in short supply. Nutrition has an important influence on flower and fruit production. The fertilizer experiments in Michigan were initiated about the time that workers reported increased seed production on forest trees in other parts of the United States (1, 5, 6, 7) after fertilization. Nitrogen and phosphorus appeared to be the "major added nutrients which stimulated production. A recent report from England (4) contradicted reports supporting the effectiveness of complete fertilizer additions to several tree species.
