SUBSTANTIAL advances have been made in refining the traditional fertiliser
recommendations for sugarcane production in Australia. These refinements have
led to the development of sets of soil-specific nutrient management guidelines
for use at district level with the aim of being appropriate for current and
evolving farming systems. Fundamental to these changes is the recognition of
differences in soil type and the need for appropriate management of nutrient
inputs that reflect these differences. Ultimately, the aim is to ensure optimum
productivity, profitability and environmental responsibility on-farm. Over the
past 6-7 years, Clyde, Fay and Jay Hubert, the owners of Amaryllys Holdings, a
20 000 t sugarcane enterprise consisting of several farms north of Bundaberg,
have co-operated participatively in this process. This paper describes the basis
for the modified nutrient management guidelines, the land resources and the
basic farming system of Amaryllys Holdings, the results of nutrient management
trials that have been conducted on-site, implications for the farming enterprise
when adopting modified farming practices and nutrient management strategies,
and a summary of plans to enable continued sustainable sugarcane production on
these farms.
