McLaren, R.G. - - 2010
In this study we examined the bioavailability and chemistry of Cu, Ni, and Zn in metal-spiked, biosolids-amended forest (Pinus radiata) soils that had undergone a simulated conversion back to agricultural use. Mixing of the biosolids-treated forest litter into the underlying mineral soil resulted in high concentrations of each metal in ...

A 7-year tillage experiment was conducted on a deep sand in the central wheat belt of Western Australia between 1998 and 2004 to evaluate the impact of tillage intensity [no-tillage (NT), conservation tillage (CT), and rotary tillage (RT)] on soil organic matter, microbial biomass and function, and crop yields in ...

The aim of this work was to evaluate the effects of 2 soil management systems, so called 'innovative' (INN) and 'conventional' (CON), on genetic and metabolic diversity of soil microbial communities of peach and kiwifruit orchards. INN system included minimum tillage, organic matter inputs from compost and cover crops, winter ...

No-tillage and organic farming are important strategies to improve soil quality. This study aimed to quantify the effects of the tillage systems and organic management on total organic carbon (TOC), labile C (CL), and biological indicators in an Acrisol in north-eastern Brazil. Five systems were studied: NV, native vegetation; NT/ORG, ...

The reliable assessment of soil carbon stock is of key importance for soil conservation and mitigation strategies related to reducing atmospheric carbon. Measuring and monitoring soil carbon is complex because carbon pools cycle and rates of carbon sequestration vary across the landscape due to climate, soil type, and management practices. ...
Hettiarachchi, G.M. - - 2010
The grain yield benefits of applying micronutrient fluid fertilisers over conventional granular products in calcareous sandy loam soils have been agronomically demonstrated. An understanding of the fundamental mechanisms and reactions occurring following application of these products to soils is critical to improve fertiliser management. We therefore examined the diffusion, solubility, ...

Intensive dairy operations in Australia regularly apply P fertiliser to maintain productive pasture species. However, extractable soil test P (STP) concentrations in this industry commonly exceed those required to maximise pasture production, a situation which can increase the risk of P loss to surrounding waterways. The current study examined relationships ...
Ludwig, B. - - 2010
Predicting chemical and biological reactions during unsaturated flow through soils is complex, and the accuracy of model predictions is open to question. Objectives were to test how accurately the transport of nutrients ([Ca.sup.2+], [Mg.sup.2+], [K.sup.+], N[H.sub.4.sup.+], and N[O.sub.3.sup.-]) in soils can be predicted when differing amounts of nutrients or acid ...
Biggs, A.J.W. - - 2010
Soils at 4 saline lakes (Wyara, Numalla, Wombah and Bindegolly) in semi-arid south-western Queensland were described and sampled to determine soil attributes that assist in the delineation of wetlands. Up to 4 sites were described in transects perpendicular to the lake edge. Samples from fixed depths were analysed for limited ...

Calculation of soil acidification rates requires knowledge of pH buffering capacity (pHBC), which is measured using titration methods. The pHBC is often quoted as a single value for a particular soil, implying a linear relationship between pH and the amount of acid or alkali added. However, over its whole range, ...
