Sugarcane and soil acidity – why we should be worried?
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 ...
Long-term profitability of liming to manage soil acidity in sugarcane: Tully, North Queensland.
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 ...
Managing soil acidification for sustained profitability in sugarcane farming systems in northern Queensland
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.
Concepts and value of the nitrogen guidelines contained in the Australian sugar industry's 'SIX EASY STEPS'nutrient management program.
The paper summarises the alternative N management strategies that occur within the Australian sugar industry. It describes best-practice nutrient management and the concepts that underpin the SIX EASY STEPS program, and ...
Reducing soil physical constraints under sugarcane
This work compared growing sugarcane in 1.5 m rows with 1.8 m dual rows (0.3 m apart) as a strategy to reduce soil physical constraints to sugarcane productivity by matching crop row spacing to equipment track widths. ...
Long-term effects of lime additions on sugarcane yield and soil chemical properties in north Queensland
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 ...
Extension and adoption of the ‘SIX EASY STEPS’ nutrient management program in sugarcane production in North Queensland
In tropical north Queensland, the need for accelerated adoption of best-practice nutrient management has become more urgent because of increasing pressures for profitable cane production to be achieved in combination with ...
Does prolonged green cane trash retention influence nitrogen requirements of the sugarcane crop in the wet tropics
Since the introduction of green cane trash blanketing (GCTB), there has been ongoing interest in its potential to contribute to the nitrogen (N) requirements of the sugarcane crop. An experiment was established at Tully ...
Research aimed at enhancing nitrogen management guidelines for the SIX EASY STEPS program
This paper provides a summary of current trials that are being conducted within this program.
Alternative nitrogen management strategies for sugarcane production in Australia: the essence of what they mean
The Australian sugar industry currently faces a combination of escalating input costs, moderately low sugar prices, decreasing cane supply and the requirement to illustrate its commitment to being environmentally responsible. ...
