Evaluating the nutritional status of Fraser fir [Abies fraseri (Pursh) Poir.] Christmas trees using foliar analysis and DRIS application
… studies were conducted with Fraser fir Christmas trees to determine the variation in foliar nitrogen (N) , phosphorus (P) , potassium (K), calcium (Ca), and magnesium (Mg) levels among plantation ages, sample locations within the crown, and effects due to seasonal changes. Extensive variation in …

Earthworms in the Urban Environment: Can Population Augmentation Improve Urban Soil Properties?
… essential ecological functions, and their performance is dependent on soil quality, which is often degraded by human activity. Because earthworms play a key role in soil health, augmenting earthworm populations in urban soils may improve tree performance. However, we know very little about …
