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. ...
Acid sulfate soils in canegrowing regions of northern New South Wales
(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 ...
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 ...
Extent of zinc deficiency in cane growing soils of North Queensland.SRDC Project BS67S - Final report.
(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
(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 ...
