Manual aims at better interpretation and presentation of laboratory chemical and physical data primarily within reports using soils, but has relevance to soil sampling and interpretations within the wider framework of agricultural use, environmental impact statements, contaminated lands, town planning. There is an increasing need for objective soil data within all aspects of the land use decision-making process. To gain maximum value from the analytical data, an appreciation is needed of the significance of the different soil properties, profile trends and the degree to which properties can vary. Basic to this is the distinction which must be drawn between the characteristics of a relatively undisturbed area (reflecting the long-term development of the soil) and those significantly changed by human activities within a much shorter time-span. Quality interpretation is the primary concern. The manual also addresses problems of data validity and transfer. It outlines sampling procedures, choice of appropriate soil tests and methods of raw data manipulation necessary prior to publication. The relationships between laboratory determinations and the field situations are discussed for each chemical and physical property, identifying conversions where available.
