Coastal Plains of the Northern Territory.; Soils report


These reports describes the land resource mapping over the Northern Territory coastal plains region. The surveyed area was mapped at a scale of 1:50,000. The mapped land units are described using the dominate soils, topography and vegetation. The potential land use and limitations for each land unit are also briefly described.


There are three different reports attached to this record: Report on the land units of the coastal plains / K.J.Day; Soils of the coastal plains, Northern Territory, Australia / A.D.L. Hooper; and Soils report (coastal plains survey 1968,69,70 / K.J. Day

I 6. which form minor aquifers in this layer. Two sub-types are defined to distinguish an upper,seasonally drained intensely mottled horizon from a lower horizon of lightly mottled, red sandy clay. M lightly mottled Mm very strongly mottled Total salt contents show a similar range in the M layers a~ in the related L layers being lowest at the margin of the Kosher land system -(total salts 0.02-0.08%, chlorides 0.006%-0.02%) and increasing progressively away from the margins as surface A and L layers deepen and lenses of E layers intervene. Total salt contents increase to .Ol% and chlorides to .06%. Ground water has total salt contents of 0.07% near the margin increasing to 0.27% Ey layers Permeabilities range from 6.10 ft/day to 3.30 ft/ day. B. Environment and Layer Combinations The depositional layers and their inferred disposition in cross sections of the plains are illustrated in Fig. 1. The two sections are set out to indicate the features of two main categories in which the layers occur in a regular sequence. Salinity characteristics of the layers can also be grouped into the two categories. On these criteria soil series have been defined and their range of occurrence indicated within the land systems represented in the study area. (i) Riverine environment.- Profiles with a sequence of A - Eb - G layers dominate where deposition was mainly influenced by the Adelaide River. Salinities are high and chlorides constitute over 50% of the total salts in most cases. During the dry season the Adelaide River (in common
