Using a legacy soil sample to develop a mid-IR spectral library.(Report)
February 1, 2008... Introduction Diffuse reflectance spectroscopy (DRS) has been used in soil science research since the 1950s and '60s (e.g. Brooks 1952; Bowers and Hanks 1965). However, it is only in approximately the last 20 years, most likely coinciding...

Long-term acidification of a Brazilian Acrisol as affected by no till cropping systems and nitrogen fertiliser.
February 1, 2008... Abstract. Cropping systems and N fertilisation affect soil acidification mainly due to the removal of alkaline plant material from the field and nitrate leaching. The study evaluated the acidification of a subtropical soil under no till...

Land use effects on soil quality indicators in north-eastern Iran.
February 1, 2008... Introduction Increased demand for housing, excessive collection of firewood, commercial logging, shifting cultivation, over grazing, and uncontrolled fires have collectively resulted in natural resources degradation through deforestation...

The ability of Distichlis spicata to grow sustainably within a saline discharge zone while improving the soil chemical and physical properties.(Report)
February 1, 2008... Introduction Soil salinity is a major issue within many Australian farming systems throughout southern Australia. The area affected by or at risk to salinity, due to shallow or rising water tables, was estimated at 5.7 million hectares in...

Land application of farm dairy effluent to a mole and pipe drained soil: implications for nutrient enrichment of winter-spring drainage.(Report)
February 1, 2008... Introduction Intensive dairy farming has undergone considerable expansion in New Zealand over the past 10 years, with a 44% increase in national dairy cow numbers (Livestock Improvement 2003). Much of this expansion has occurred on...

Adsorption isotherms of copper, lead, nickel, and zinc in two Chilean soils in single- and multi-component systems: sewage sludge impact on the adsorption isotherms of Diguillin soil.(Report)
February 1, 2008... Introduction The use of wastes and residues, especially from industrial and urban sources, needs to be accomplished with the minimum hazardous impact in the environment. A current practice is the application of waste to agricultural lands....

Links between dryland salinity, mosquito vectors, and Ross River Virus disease in southern inland Queensland--an example and potential implications.(Short Communication)
February 1, 2008... Introduction The extent and importance of secondary salinity (salinity induced by the activities of man) in Australia has been widely discussed for many decades, and summarised at the national scale in documents such as the National Land...

Absorption of gypsum solution by a potassic soil: a data set.(Report)
February 1, 2008... Introduction Liquid effluents used for irrigation at 5 intensive piggeries in south-eastern Australia significantly increased the potassium adsorption ratio (KAR) (Richards 1954) in the soil saturation extracts and the exchangeable...

Sources of nitrous oxide from [sup.15]N-labelled animal urine and urea fertiliser with and without a nitrification inhibitor, dicyandiamide (DCD).(Report)
February 1, 2008... Introduction Nitrous oxide ([N.sub.2]O) is a potent greenhouse gas with a long-term global warming potential 310 times that of carbon dioxide (C[O.sub.2]) (IPCC 1995). In New Zealand, about half (49.4%) of the total greenhouse gas emitted...

Distribution of fractions of zinc and their contribution towards availability and plant uptake of zinc under long-term maize (Zea mays L.)--wheat (Triticum aestivum L.) cropping on an Inceptisol.(Report)
February 1, 2008... Introduction Micronutrient deficiencies, particularly zinc (Zn) deficiency, in field crops are widespread all over the world because of increased Zn demands of intensive cropping systems and adoption of high-yielding cultivars with...
