The teaching-research-industry-learning (TRIL) nexus has been used to develop a framework for the learning and teaching of soil science applicable to a range of recipients, particularly campus-based students and practicing farm advisors. To develop s

Soil Science is a unique discipline concerning a complex material that is part of many natural and utilitarian systems. As such, the teaching of Soil Science requires principles that reflect the nature of soil and the practices of soil scientists. Be

We report an image analysis study of soil macropore attributes in the top 100 mm of a winter barley (Hordeum vulgaris L.) seedbed in Scotland that had been prepared by chisel-ploughing and secondary tillage of a clay loam soil using either zero, redu

At Koongarra, Australia, three drill cores from the Cahill Schist Formation containing U-ore, and regolith above it containing secondary U-ore, were studied to ascertain the distribution of rare earth elements (REEs) and U. The unaltered schist has a

Summary Conventional methods of soil classification are based largely on hierarchies and treat soil attribute value ranges as exactly specifiable quantities. Misclassification may result from ignoring the continuous complex nature of soil variation,

The predominant methods of measuring soil structural stability are confined to laboratory methods that, by their nature, do not quantify the field stability of the soil. An instrument is presented here for measuring the soil structural stability in s

The micromorphology and elemental composition of celestobarite crystals in a duripan from central Australia are examined. These crystals are flabellate (fan-shaped), have a Ba/Sr ratio of 11.1, and are up to 50 μm in size. The location of the celest

Adjacent cultivated and never-cultivated areas of land were compared for a variety of chemical and physical properties to determine the effect of traditional cultivation practices on an Australian Rhodoxeralf. Those properties which changed most as a

Currently there is a lack of quantitative data on the functional classification of soil structure, particularly in routine soil surveys, because field physical measurements of flow characteristics are slow and require expertise. A simple air permeame
