Acid sulfate soils in canegrowing regions of northern New South Wales
Reghenzani, JR (1995)Acid sulfate subsoils contain iron pyrites (FeS2). Pyrites is stable under anaerobic (saturated) conditions, but when oxidised forms sufuric acid and releases mobile Fe2+ ion. Soil pH can be reduced to as low as 2 and ... -
Evaluation of the effects of rare earth elements on sugarcane in North Queensland
Reghenzani, JR (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 ... -
Extent of zinc deficiency in cane growing soils of North Queensland.
Reghenzani, JR (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 ... -
Soil constraints to productivity improvement
Croft, BJ; Magarey, RC; Hurney, AP; Reghenzani, JR (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. ... -
Soil constraints to productivity improvement
Croft, BJ; Magarey, RC; Hurney, AP; Reghenzani, JR (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 ... -
The effect of zinc deficiency as a factor limiting sugarcane growth (SRC Project BS14S - Final Report)
Reghenzani, JR (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 ...
