A new model (soil water under forest, SWUF) is suitable for predicting the daily water content within both surface soil layers and the sub-soil under a range of forest types, and is suitable for use in models of mineralisation of soil organic matter

Since the appearance of Essigella californica in Australia in 1998, outbreaks of the aphid have been associated with atypical needle yellowing, premature senescence and defoliation of mid-rotation Pinus radiata plantations across Australia. This stud

Summary Simulation models of net mineralization of nitrogen (N) in soil need to be able to incorporate the effect of soil water. Our objective was to identify and define the best way of expressing soil water and its effect on net mineralization acros

Soil from beneath an 11-year-old P. radiata plantation was incubated under a factorial combination of temperature (5,10,15,20 or 25°C) and moisture (10,20,40,60,80 or 100% of field capacity; 0.26 g g−1) for 15, 30 or 60 days. Mineral N production

We compared three methods of estimating soil organic carbon (dichromate oxidation with and without external heating and loss‐on‐ignition) with a method for total carbon measured in an automated resistance furnace. In 38 surface (0–150 mm) podzo

A new empirical model (SNAP) combines a simple laboratory measurement of the basal rate of N mineralisation with the modifying effects of daily temperature and water content to predict seasonal and annual rates of mineralisation of forest soils. Shor

The relationship between selected chemical properties and nitrogen mineralization and nitrification was examined in soils collected from 39 sites of varying history. All sites were on podzolized sands; such soils represent more than 95% of the P. rad

Pinusradiata may exhibit moderate to severe stem deformity (Toorour syndrome) when planted on ex-pasture sites in southern Australia. However, the deformity does not occur on ex-eucalypt forest sites unless N fertilizer is applied. While the symptoms

Urea and superphosphate dramatically increased the concentrations of exchangeable ammonium-N and water-soluble P in incubated forest floor samples. Urea also increased absolute but not relative nitrate production. Superphosphate depressed pH while ur
