Nutrient Input By Precipitation In Northern Minnesota Forest Ecosystem, Nicholas B. Comerford, Edwin H. White
Journal of the Minnesota Academy of Science
Yearly precipitation was sampled and analyzed for total content of N, P, K, Ca and Mg to assess the role of gross precipitation in adding nutrient elements to sites in northern Minnesota. Data from this study is part of a larger effort to determine the effects of mechanized harvesting on the nutrient cycle. Data from the present study indicate that it is unlikely that total yearly precipitation will be able to maintain adequate levels of site productivity on areas that are full-tree harvested. Total yearly nutrient income in lbs/acre was N - 3.9; P - .23; K - 2.29; Ca …
