Aside from the measurement induced bias and even within assumed homogeneous soil strata, natural soils are variable in their properties. The scarcity in field test results, characteristic to ...

From pH 7 to 0 the soil is increasingly more acidic and from pH 7 to 14 the soil is increasingly more alkaline or basic. Soil pH provides various clues about soil properties and is easily determined.

Soils which have not completed the consolidation under their own weight are also included in this group. The study of soil behaviour may be approached in four main characteristic groups; index ...

Gley soils represent the most extensive soil cover in Scotland. These soils are found on gentler slopes or in areas of high rainfall where the water does not drain away readily. All the glacial ...

As soil dries, plants limit water loss by closing tiny apertures called stomata in their leaves. A global analysis reveals ...

Any system of soil classification involves grouping the different soil types into categories that possess similar properties and, in so doing, providing the engineer with a systematic method of soil ...

Different soils have different properties depending on their composition. Sandy soil is pale coloured and has large particles. These create lots of small air gaps. Water drains through them easily ...
