This study investigates the in vitro formation of Ca-oxalates and glushinskite through fungal interaction with carbonate substrates and seawater as a process of biologically induced metal recycling and neo-mineral formation. The study also emphasizes the role of the substrates as metal donors. In the first experiment, thin sections prepared from dolomitic rock samples of Terwagne Formation (Car...

Decline of sugar maple in North American forests has been attributed to changes in soil calcium (Ca) and nitrogen (N) by acidic precipitation. Although N is an essential and usually a limiting factor in forests, atmospheric N deposition may cause N-saturation leading to loss of soil Ca. Such changes can affect carbon gain and growth of sugar maple trees and seedlings. We applied a 22 factorial ...

It has been suggested that raising soil pH through liming could reduce the impact of whitegrub on crop yield in the treated soil. To test this hypothesis, whitegrub incidence was monitored in a trial designed to examine the effects of various lime treatments on crop yields of varieties N16 and N12. Lime was applied at two rates (5 and 10 t/ha) and in combination with gypsum at 5 t/ha each. Resu...
