Reef Plan Herbert Water Quality Monitoring Program (HWQMP) Final report for monitoring undertaken between 2011 and 2014
(Centre for Tropical Water & Aquatic Ecosystem Research (TropWATER) Publication, James Cook University, 2015)The Herbert River Catchment is situated in the Wet Tropics Region of Far North Queensland and covers approximately 10,000 square kilometres and unlike many other coastal streams in the wet tropics, the Herbert River has a ... -
Plant cane responses to silicated products in the Mossman, Innisfail and Bundaberg districts
(2001)Within the Australian sugar industry there is a lack of information on potential sources of silicated mate1ials and on their rates of application_ Field experiments were established during the 1999 planting season to ... -
Assessing nitrate losses below sugarcane crops.
(1994)The location of the sugar industry in a region of great ecological sensitivity, together with rapid urban/tourist growth, further increases the significance of nutrient losses to ground and surface waters. Nitrate losses ... -
Long-term effects of lime additions on sugarcane yield and soil chemical properties in north Queensland
(2000)In many highly weathered soils of the humid tropics, crop exploitation of the subsoil environment is limited through acid soil infertility. Since the use of mechanical profile modification is often prohibitive, surface ... -
Tatura Sodicity Conference: knowledge gaps in sodicity research for major agricultural industries
(2002)This paper summarises the outcomes of the International Sodicity Conference, ‘Sodicity Issues in Agricultural Industries — Current Research and Future Directions -
Quantification and remediation of soil chemical degradation in tropical australia, China and Thailand
(2003)The paper focuses on quantifying chemical degradation through‘benchmarking' using data from paired sites in tropical China and Thailand using surface charge finger-printing. -
Influence of soybean residue management on nitrogen mineralisation and leaching and soil pH in a wet tropical environment
(2000)A study was undertaken at the Sugar Yield Decline Joint Venture sub-station at Feluga in north Queensland in 1998 to investigate the effect of soybean residue management on nitrogen mineralisation and leaching, and soil pH. -
Monitoring water quality on farms: The Herbert water quality monitoring project
(2008)The Herbert Water Quality Monitoring project was established with the aim of establishing a network of water quality monitoring sites in small catchments within the Herbert cane area and where growers were given the ... -
Long-term profitability of liming to manage soil acidity in sugarcane: Tully, North Queensland.
(1998)Management of soil fertility is an important factor influencing the long-term profitability of sugar production systems. In this respect, soil acidification associated with repeated cropping may result in declining ... -
Silicon research down under: Past, present and future
(2001)Recent research has identified specific Si responses and delineated soils having sub-optimal levels of Si. Future research will focus on developing response functions on a range of soil types identified as Si responsive, ... -
Sugarcane yield and nitrogen uptake in relation to profiles of mineral-nitrogen in the soil
(1995)Efficient use of fertiliser nitrogen in sugarcane production requires a matching of N supply from all sources with N demand by the crop. Major sources include fertilisers, mineral N in the soil and within-season mineralisation. ... -
SWIMv2 in APSIM : An integrated plant, soil, water and solute modelling framework
(1996)SWIM Version 2 (1) is a soil water and nutrient balance model based on a numerical solution of the Richards’ and Convection-Dispersion equations. APSIM (2) is a modular agricultural production systems modelling environment ... -
Measurement of water and solute movement in large 'undisturbed' soil cores: Analysis of Macknade and Bundaberg data
(2001)In this report we describe results of leaching experiments carried out on large undisturbed soil cores (300 mm long × 216 mm diameter) obtained from key field sites in Queensland -
Sugarcane and soil acidity – why we should be worried?
(1997)Production systems which promote soil acidification are unsustainable in terms of the maintenance of the soil resource. Potential mechanisms of acidification are discussed with respect to proton generating reactions and ... -
An assessment of soil and plant silicon levels in north Queensland
(1999)Sub-optimal levels of soil silicon (Si) can result in decreased cane and sugar yields. In general, soils of the wet tropics that have undergone significant weathering invariably have inherently low Si levels. To date, ... -
An assessment of current silicon status of sugarcane production soils from Tully to Mossman
(2001)A survey of soils currently used for sugarcane production on the wet tropical coast of north Queensland was unde11akcn during the 1999-2000 growing season. The regions surveyed included the Atherton Tablelands, Mulgrave, ... -
Managing soil acidification for sustained profitability in sugarcane farming systems in northern Queensland
(1998)The main objective of this paper is to describe a framework to analyse the longer term economic viability of cane farming systems in the wet tropics, with particular emphasis on soil acidity management. -
Improving soybean and nitrogen management in sugar cane systems in subtropical NSW
(2010)Some sugar cane growers are not fully realising the economic benefit of soybean crops to their cane production systems or the environmental benefit through minimising the use of N fertilisers. This paper reports on the ... -
Is lime doing what we want it to?
(1998)This paper explores the implications of these results and identifies other indicators that might promote a better understanding and more targeted use of liming products by the sugar industry and by Queenslands' other ...
