Opportunities to directly study infrequent forest disturbance events often lead to valuable information about vegetation dynamics. In mesic temperate forests of North America, stand-replacing crown fire occurs infrequently, with a return interval of 2000-3000 years. Rare chance events, however, may have profound impacts on the developmental trajectories of forest ecosystems. For example, it has...

After a soil fertility baseline had been'determined for the Georgia Forestry Commission's (GFC) Morgan Nursery, a single nursery protocol consistently produced high quality oak seedlings. The fertility baseline developed at the Institute of Tree Root Biology (ITRB) Whitehall Experimental Nursery and adjusted for three GFC nurseries has a background target level at CA, K, P, Mg, Cu. Zn, and B of...

Fine-scale spatial information on soil properties is needed to successfully implement precision agriculture. Proximal gamma-ray spectroscopy has recently emerged as a promising tool to collect fine-scale soil information. The objective of this study was to evaluate a proximal gamma-ray spectrometer to predict several soil properties using energy-windows and full-spectrum analysis methods in two...

Inoculation alfalfa seeds with the right Rhizobium strain (nitrogen-fixing bacteria) can stimulate root nodulation and improve plant growth yield. Different inoculation methods are used to inoculate seeds; however, effect of these on germination is not well documented. In present study, was evaluated after using different methods, i.e. Arabic gum solution glucose as adhesive substances surface ...
