Fertilizer Trials on Containerized Red Pine

Nitrate (N03), ammonium (NH4), and urea forms of nitrogen fertilizers were tested on containerized red pine (Pinus resinosa, Ait.) at four locations in Michigan, Wisconsin, and Minnesota. Height, stem caliper, shoot and root dry weight, were all significantly different between treatments. Formulations with both high N03 and NH4 produced larger seedlings at all locations at 14 weeks from sowing. Formulations with just high NH4 Produced larger seedlings at three locations at 14 weeks old.
