Behaviour and Microstructure of Clay Mineralsties of the clays in any soil are of fundamental importance to the behaviour of the soil, but this behaviour is strongly influenced also by the climatic conditions, the soil organisms, the topography, and the length of time for soil genesis.

Some Properties of Clays and of other Soil Colloids and their Influences on Soilsr qualitatively or quantitatively. When soils contain more than twenty per cent clay, they start to exhibit properties that are typical of ‘clay’ soils, such as cohesion, shrink-swell ability, decreasing permeability, and an aggregate structure in which clay particles contribute to the binding toget

Some Properties of Soil and Synthetic Iron Oxidesthe humic substances, the iron oxides are among the smallest particles found in soils. From a comparison of the sizes of common soil minerals it can be seen that iron oxides usually belong to those soil minerals which have very small particle sizes. Consequently, iron oxide particles can contribute

Some Observations on the Formation and Transformation of Iron Oxidesdes the oxy-hydroxides and the hydrous oxides) influences such diverse properties as, for example, fertility, structure, permeability, soil colour, and profile differentiation. They can exercise a role in microbial respiration, and they can act as a sink and/or source of potentially toxic heavy meta
