Soil Colloids and the Soil Solution
1991In the companion volume to this book (‘Soil Colloids and Their Associations in Aggregates’; M.F. De Boodt, M.H.B. Hayes, and A. Herbillon, eds.; Plenum Press, New York and London, 1990), attention was focused on the composition and structures of the colloidal components of soils and on the associations in aggregates between these and the other ...

Soil Biology: Soil Animals and Soil Acidity [PDF]
, 1994 The role of soil animals is in general poorly known. Several studies have shown that soil fauna may accelerate the decomposition rate and contribute to the release of plant nutrients, but there is a need for more exact quantitative knowledge in this field (e.g., Anderson et al.

SOIL EXTRACT IN SOIL MICROBIOLOGY
Canadian Journal of Microbiology, 1958Soil extract contains unidentified growth factors not present in other materials. In this study the extract was considered critically in so far as various treatments affect numbers of bacteria developing on soil-extract agar. Dilution of the extract to 1/10th concentration produced lower counts in most soils.

Equations for the soil-water characteristic curve
, 1994The soil-water characteristic curve can be used to estimate various parameters used to describe unsaturated soil behaviour. A general equation for the soil-water characteristic curve is proposed.

Proceedings of the Prehistoric Society, 1982
During the summer of 1980, excavations at Shaugh Moor were extended to the Saddlesborough reave, it was hoped to establish the nature of the land boundaries which characterise this part of Dartmoor.In this area the reave runs downslope in a south-easterly direction away from Saddlesborough and it was investigated by a number of sections at ...
