Evaluating the leaf chlorophyll meter as a tool for nitrogen management in sugarcane
(1995)
Nitrogen is an important constituent of chlorophyll, the compound that gives plants their green colour and the compound that absorbs radiation energy as the basis of plant growth. When nitrogen is in short supply, the ...
Assessing clonal and nitrogen interaction on ccs in sugarcane in the wet tropis ; SRDC project BSS180 final report
(2003)
There has been a negative trend in CCS in the Tully-Mossman region since the mid-1960s that has been linked to increased extraneous matter and suckers in the cane supply. The situation had become particularly bad during ...
BSES technical report TE11004 - Burdekin nitrogen project - September 2011
(2011)
In response to the introduction of the regulated method of determining N, some canegrowers in the Burdekin district (which produces approximately 25% of Queensland's sugarcane) expressed concern that sugarcane yields could ...
Overcoming on-farm constraints to productivity and profitability in a wet tropical area
(2003)
The CCS in the wet tropics has been declining steadily for over three decades, a period in which green cane harvesting-trash blanketing (GCTB) has become standard practice among growers throughout the wet tropics. In the ...
Evaluating the potential for improved sugar yields by assessing the climatic and soil constraints to production in southern cane-growing districts
(1999)
This project conducted strategic research to better understand the processes of yield accumulation in low temperature NSW environments and to identify limits to yield. The fundamental knowledge gained in this project can ...
A stocktake of the levels and sources of nitrate in groundwaters associated with sugarcane areas
(2000)
Water containing high concentrations of nitrate is unfit for human consumption and, if discharging to freshwater or marine habitats, can contribute to algal blooms and eutrophication. Previous studies have found elevated ...
Project No 2025: Final report bench testing of new nitrogen products for potential ammonia volatilisation: when boradcast onto soil or sugarcane trash (N-gold "A", N-gold "B")
(1996)
N-Gold "A" and N-Gold "B" are granulated products containing urea and calcium oxide with 42.4 and 43.2 % N and 1.5 and 1.3 % Ca respectively. When broadcast onto soil or a green cane trash blanket, ammonia volatilisation ...
Comparison of 'into' and 'beside' stool nitrogen placement
(1992)
There are now two alternative methods of subsurface nitrogen placement available: beside the stool or into the stool. The second, into the stool treatment, is easier to accomplish. Comparison of cane yields from strips ...
Nitrate retention at depth under sugarcane in Far North Queensland Wet Tropics
(2002)
Nitrogen mass-balance studies for sugarcane grown on Ferrosols (Krasnozem) in the Far North Queensland (FNQ) wet tropics have shown 30 to 50 kg N/ha/yr of the applied fertiliser+N leached below the root-zone (<0.75 m) as ...
A review of nitrogen use efficiency in sugarcane
(Sugar Research Australia Limited, 2014)
The Great Barrier Reef (GBR) is the world’s largest coral reef ecosystem, providing both substantial economic benefit to Australia and significant international ecological value. The health of the GBR is under pressure ...
