Mr402: The Soils Of Maine, John A. Ferwerda, Kenneth J. Laflamme, Norman R. Kalloch Jr., Robert V. Rourke

Miscellaneous Reports

This report describes the soils of Maine. It includes information on soil formation, soil classification, soil map derivation, and map unit descriptions. This document file contains an 8.5X11-inch version of the general soil map of Maine. The full-size (22x33-inch) map is available in an accompanying file.

Tb165: Chemical And Physical Properties Of The Danforth, Elliotsville, Peacham, And Penquis Soil Map Units, R. V. Rourke

Technical Bulletins

The soils reported in this bulletin have developed in several different parent materials. The Danforth soil has developed from very deep, well drained, loose, high coarse fragment till derived from slate and fine-grained metasandstone. The Elliottsville soils have developed in moderately deep, well drained till derived from slates, metasandstones, phyllite and schists. The Penquis soils developed in moderately deep, well drained till of similar lithology as Elliottsville, but with a higher component of weathered and crushable rock fragments throughout the soil profile. Peacham soils are developed in very deep, very poorly drained, dense till derived from phyllite, schist, and granite.

A Guide To Mechanical Range Regeneration, J. Addison

Bulletins 4000 -

The main objective of this Bulletin is to describe mechanical methods of promoting rangeland regeneration and how to determine which is the most appropriate to use on any particular site. Mechanical regeneration methods are not 'quick fix' but may be used to advantage in some rangeland regeneration strategies.

Western Australia Soil Acidity Research And Development Update 1997 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

There is a lot of lime being spread in Western Australia – or is there?

In fact, the Australian Bureau of Statistics agricultural census paints a picture showing that we are still far short of the amount of lime that should be getting on to the ground.

For many years Western Australian soils acidified without significant production penalties. The soil pH was at values that were not affecting plant growth. However, over the last decade or so, large areas of soils have reached the point where production is being affected. In addition, we are now introducing plant species such as …
