Decomposition dynamics of plant materials in relation to nitrogen availability and biochemistry determined by NMR and wet-chemical analysis
Abstract Improved understanding of the interactive relationships of plant material decomposition kinetics to biochemical characteristics and nitrogen availability is required for terrestrial C… Expand
NITROUS OXIDE EMISSIONS FROM SUGARCANE SOILS: EFFECTS OF UREA FORMS AND APPLICATION RATE
THE COMBINATION of high nitrogen (N) fertiliser application rates and cane residue retention with the wet and warm climate in the Australian sugarcane regions provides favourable conditions for the… Expand
Soil phosphorus tests I: What soil phosphorus pools and processes do they measure?
Abstract. The phosphorus (P) status of 535 surface soils from all states of Australia was assessed using the following soil P tests: Colwell-P (0.5 m NaHCO3), Olsen-P (0.5 m NaHCO3), BSES-P (0.005… Expand
Development of key soil health indicators for the Australian banana industry
To improve the sustainability and environmental accountability of the banana industry there is a need to develop a set of soil health indicators that integrate physical, chemical and biological soil… Expand
Effects of urea formulations, application rates and crop residue retention on N2O emissions from sugarcane fields in Australia
Abstract High fertiliser nitrogen (N) application rates, crop residue (trash) retention and the wet and warm climatic conditions in sugarcane (Saccharum officinarum) cropping may favour nitrous oxide… Expand
Tracing the source of sediment and phosphorus into the Great Barrier Reef lagoon
Neodymium and strontium isotopic systematics show that terrestrial phosphorus (P) entering the inner Great Barrier Reef (GBR) is dominated by the transport and dispersal of fine-grained basaltic… Expand
Soil phosphorus—crop response calibration relationships and criteria for oilseeds grain legumes and summer cereal crops grown in Australia
Abstract. Australian cropping systems are dominated by winter cereals; however, grain legumes, oilseeds and summer cereals play an important role as break crops. Inputs of phosphorus (P) fertiliser… Expand
NITROGEN FERTILISER GUIDELINES IN PERSPECTIVE By
SUBSTANTIAL advances in fine-tuning nitrogen (N) fertiliser recommendations have recently been made in the Australian sugar industry. Traditionally N recommendations were general in nature for use… Expand
Sustainable nutrient management - delivering the message to the Australian sugar industry.
Fertiliser guidelines in the Australian sugar industry have recently undergone substantial change. Over an eight-year period, the generalised fertiliser recommendations for use across regions and… Expand
Response of field-grown maize to applied magnesium in acidic soils in north-eastern Australia
Split-plot field experiments, with main plots consisting of various rates of calcitic lime and single rates of dolomite, gypsum, and calcium silicate, were conducted at each of 4 sites to determine… Expand
