Soil compaction studies - Mossman
(1975)Study was initiated to investigate the effects of the different bin transport systems on soil compaction. Compaction under dry soil conditions does not appear to be a serious problem and can ve overcome by cultivation. ... -
Progress report on BSES and WRC studies of water quality in Woongarra-Pemberton area - July 1981
(1981)This report summarizes results of a pot trial comparing bore and surface water; co-operative monitoring of water-table levels with the Water Resources Commission; field trials with various ameliorants; and a field survey ... -
Evaluation of the effects of rare earth elements on sugarcane in North Queensland
(1989)During 1988 BSES submitted a proposal to the Australian Academy of Technological Sciences and Engineering for partial funding of a research project to investigate the response of sugarcane in North Queensland to rare earth ... -
Evaluation of biostil dunder and mixtures with nitrogen fertilisers for sugarcane nutrition
(1990)The aims of this project were: (a) to measure the cane and sugar yield responses from the application of biostil dunder on its own and in mixtures with nitrogen fertilisers in field trials; and (b) to assess the suitability ... -
Soil constraints to productivity improvement
(1990)Yields of most crops are known to decrease if that crop is grown continuously without fallowing or rotation with other crop species. Sugarcane has been grown continuously on many fields in Queensland for 50-100 years. ... -
The effect of zinc deficiency as a factor limiting sugarcane growth (SRC Project BS14S - Final Report)
(1990)Results from this project confirm that substantial yield responses to zinc application can be expected in deficient soils in North Queensland. Deficiency is commonly associated with lime application. Three soil and two ... -
Consequences of future management options for the Bremerhaven drainage system.
(1991)The following questions were referred to BSES by the Woongoolba Flood Mitigation Advisory Committee: (1) The possible short and long-term effect on all classes of land of lowering the watertable in the Bremerhaven System. ... -
The effect of soil physical properties on growth and yield of sugarcane
(1991)The literature reporting the effect of soil physical properties on sugarcane growth and yield has been reviewed and areas for further investigation are suggested. There is conflicting evidence in relation to the number ... -
Soil constraints to productivity improvement
(1991)Evidence from investigations into fumigation, fungicide application, fallowing and growth of sugarcane on recently cultivated soils strongly suggests that yields in established cane growing areas are being restricted by ... -
Improving the efficiency of nitrogen fertilisation of sugarcane under minimum till and trash conservation cultural conditions (Final report SRDC Project BS37S)
(1992)Objectives of the experiments were (1) Determine the extent of NH3 volatilisation when urea and ammonium sulfate are applied to the surface of a trash blanket in four cane-growing regions. Evaluate the effect of various ... -
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 ... -
Phytotoxic substances associated with the decomposition of sugarcane trash residues. (Final report SRDC Project BS31S)
(1992)Ratooning through trash blankets is generally effective with minor exceptions for certain varieties and in cold or waterlogged soils. Information was required to determine whether these effects are normal reactions of slow ... -
Report on evaluation of nutrient enhancement of biodunder for cane growth
(1992)Three yield trials were conducted to evaluate strategies for the use of biodunder as a fertiliser for sugarcane. Cane growth in the trials was adversely affected by the weather, which was dry in summer, followed by ... -
Development of criteria for draining shallow watertables in the Isis irrigation area
(1993)This project was proposed to the Sugar Research Council because qualitative data suggested a significant problem with waterlogging and salinity in hydromorphic sedimentary soils in the Bundaberg to Maryborough region. ... -
Extent of zinc deficiency in cane growing soils of North Queensland.
(1993)Collation and interpretation of soil analysis data has shown a strong relationship between soil type and extractable zinc. Extractable zinc in soils followed the order: metamorphic, beach ridge and granite soils < organic ... -
The physiological and growth response of sugarcane to the sodium absorption ratio in flowing solution sand culture
(1994)The growth of sugarcane variety Q117 in sand culture using nutrient solutions with sodium absorption ratios of 0, 5, 10, 15, 20 and 30, each with a constant electrical conductivity of 1.5 dS/m was determined under glasshouse ... -
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 ... -
Evaluation of nutrient enriched biodunder for sugarcane : a review
(1995)The review looks at the advantages and disadvantages of fertilising with biodunder\urea compared with applying biodunder and urea separately. The review concludes with 6 recommendations for the use of biodunder\urea\sulfuric ... -
Project 921 - rates of biodunder for sugarcane : final report
(1995)The BSES recommendation for a maximum application rate is considered adequate to maximise returns and production for ratoon crops on the majority of Mackay soils. As the experiments were conducted only on ratoon crops, ...
