Australian Journal of Soil Research back issues from March 2007:
The prediction of soil carbon fractions using mid-infrared-partial least square analysis.
Mar 01, 2007; ... Soil organic carbon content is normally measured using some form of chemical oxidation (e.g. Walkley and Black 1934) or by dry combustion (e.g. Leco carbon determinator, Merry and Spouncer 1988) as total carbon. TOC values, however, may not adequately describe the role of carbon in many ...
An analytical tool for understanding the properties and behaviour of variable charge soils.
Mar 01, 2007; ... Introduction Although the fundamental properties of soils, and the processes occurring within them, change only slowly over time, the same cannot be said of our actual understanding of these properties and processes. Successive generations of soil scientists have provided an ...
Denitrification capacity in the vadose zone at three sites in the Lake Taupo catchment, New Zealand.

Oxygen transport in soil and the vertical distribution of roots.
Mar 01, 2007; ... Introduction For most plants to grow in soil, a proportion of the pore space needs to be filled with air (Glifiski and Stepniewski 1985). This allows for the exchange of oxygen ([0.sub.2]) and carbon dioxide (C[O.sub.2]) gases between the atmosphere and soil. The consumption of ...
A specialised soil corer for sampling tree roots.(Short Communication)
Mar 01, 2007; ... Introduction To develop biomass and carbon prediction equations for whole trees, it is necessary to measure both above- and below-ground biomass of sample trees. However, exposing and measuring entire root systems is generally not practical. Therefore, subsampling of individual ...
Sandblasting damage of narrow-leaf lupin (Lupinus angustifolius L.): a field wind tunnel simulation.
Mar 01, 2007; ... Introduction In the last 20 years, narrow-leaf lupin (Lupinus angustifolius L.) has been developed into a major dryland crop species in Australia. Previously, cropping systems in southern Australia involved either continuous cereal or pasture/cereal rotations. Legume species are ...
Indexing soil quality: a new paradigm in soil science research.

Phosphorus accumulation and other changes in soil properties as a consequence of vegetable production, Sydney region, Australia.
Mar 01, 2007; ... Introduction Vegetable production is common in many peri-urban areas around the world and is important from many agricultural, historical, cultural, social, economic, and environmental perspectives. For example, vegetable production within the Sydney region has a history as long ...
Assessment of the influence of soil structure on soil strength/soil wetness relationships on Red Ferrosols in north-west Tasmania.
Mar 01, 2007; ... Introduction Soil degradation is an important issue in soil conservation management in the north-west region of Tasmania, Australia (Cotching et al. 2002). Cultivation when soils are wetter than the plastic limit, or loading the soil with heavy traffic, can result in compaction ...
