Description

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.

Notes

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

Ground water has total salt contents of 1.4 to 1.6%,chlorides 0.4 to 0. and reaction is between 6.0 and 7.0. Permeability measurements on one sample showed K = 0.38 ft/day. (v) L - Sands or sandy clays often with iron nodules derived from the sandy and lateritic lowlands of the Kosher land system. Surface layers where drainage is good are brown and sandy, lower , or where drainage is poor, are grey or mottled grey and have hgher clay contents. Two sub-types are: Lb brown, sandy loams or sand Lg grey sandy clay Salts in this layer are low. Total salts are between .05% and 0. , chlorides 0.005 to 0. and reaction is 5.5 to 6.0. Ground water salinity is also low (total salt content 0.1% to 0. , chlorides 0.04 to 0.08%, reaction 7.0-7.1). Permeabil ity is high, K = 6.20 ft/day in a Lg layer and 10.00 ft/day in a Lb layer. (vi) M - Mottled sandy clays which always succeed the L layer. They are distinctively coloured with a red clay matrix and coarse sandy grey mottles. Intermediate yellows and greys form narrow bordering zones around these mottles
