“…(*-l') Whilst Molnar (12) found little relationship between land prices and mapped soil classes in Victoria, Australia, Thompson and Johnston(l3) found a close link between soil units and farm income in Illinois. Recently Cruickshank and Armstrong (14) claimed that soil series were not very helpful in predicting farm gross margins, but Beckett and Webster (15) suggested that their data led to the opposite conclusion.…”

Claims for the general economic benefits of soil maps as planning tools have remained largely unsubstantiated. This study offers a method of assessing the value of the information provided by a soil map. Its value depends on the quality of the map, and on the difference in payoffs between alternative management practices. Using only data normally available to agricultural planners, the value of a map may be calculated before its survey. The problem is one of decision‐taking under uncertainty. A computer programme has been compiled to calculate the benefit from soil surveys of differing quality and is applied to data from a peach‐growing area in Australia.

“…If the relationship could be established and quantified, findings could be usefully applied in agricultural land valuation. 3 Such an investigation was undertaken in 1973-4 in the southern part of New England, New South Wales (Figure 1), which was considered highly suitable as a field area because of the variety of geology, soil and topography within it. Vol.…”
