Monitoring And Managing Soil Acidity, Fionnuala Frost, Extension Officer, Northam Mar 1992

Monitoring And Managing Soil Acidity, Fionnuala Frost, Extension Officer, Northam

Bulletins 4000 -

This Bulletin provides information on how to identify acid soils and remedy the problem of excessive acidity. Material in this handbook is suitable for broadscale agricultural systems, and perennial and permanent pastures in the medium and higher rainfall areas of the State.

Acidity of both the surface and subsurface layers of soil is addressed. Each can be important in affecting plant growth and therefore the profitability of the farm.


Central Atlantic Coastal Plain - A Summary Of The Geological Evolution Of Chesapeake Bay, Eastern United States, Steven M. Colman, Jeffrey P. Halka, C. Hobbs Jan 1992

Central Atlantic Coastal Plain - A Summary Of The Geological Evolution Of Chesapeake Bay, Eastern United States, Steven M. Colman, Jeffrey P. Halka, C. Hobbs

VIMS Books and Book Chapters

The seaward margin of the U.S. Atlantic Coastal Plain has fluctuated through time, from near the Fall Line to near the edge of the present Outer Continental Shelf, owing to changes in relative sea level. The strata that underlie the Coastal Plain were deposited in environments that ranged from fully terrestrial to fully marine. Estuarine environments are critical components of the Coastal Plain; they represent the interface, otherwise known as the shoreline, between the marine and terrestrial depositional systems. The Quaternary evolution of estuaries has important implications for both documenting the history of sea-level changes and interpreting ancient coastal-plain strata. …
