Foliar Nutrient Diagnosis of Urban Sugar and Red Maples in the Great Lakes Region [PDF]
Journal of Environmental Horticulture, 1985 Samples were collected from 293 urban Acer rubrum L. and Acer saccharum Marsh. in Michigan, Ohio, Illinois and Wisconsin. Foliar analysis indicated that healthy urban maples contained lower than expected levels of N and Mn; intermediate levels of Al, Cd, Cu, Fe, Mg and Zn; and high levels of B, Ca, K, Na and P. Guides to fertilization and diagnosis are

Lentil genotypes potentially suitable for organic production in the southeastern United States
Crop Science, Volume 66, Issue 2, March/April 2026.Abstract Lentil (Lens culinaris Medikus) is a nutrient‐rich, cool‐season legume crop grown in many regions worldwide. In the United States, lentil has yet to be adapted to southeastern (SE) regions, where it can be grown as a winter crop. The objective of this research was to identify candidate lentil genotypes for adaptation to organic production in ...

Plants and Insect Eggs: First Report of a Katydid Using a Fern as Host for Oviposition
New Zealand Journal of Botany, Volume 64, Issue 1, March 2026.Ferns are the second most diverse lineage of vascular plants worldwide and are particularly abundant in tropical forests. However, the ecological significance of such remarkable diversity has been often underestimated. In this article, we report for the first time the observation of ferns, specifically Polytaenium cajenense (Desv.) Benedict ...
