x2013 Properties nature types and significance SOIL COLLOIDS The colloidal state refers to a two phase system in which one material in a very finely divided state is dispersed through second p. The soil should be neutral or slightly acidic with pH 65 to 70 having high organic content Very light sandy soils are not recommended owing to their poor moisture holding properties Climate Light Light is one of the most important climatic factors i DR AMINA TARIQ.
