Glasshouse and field experiments were conducted to determine the effects of biocides and rotation breaks on deleterious soil organisms associated with the poor early growth and subsequent yield decline of sugarcane grown in continuous monoculture. Fumigation of a soil that had been under sugarcane monoculture with minimal breaks for more than 30 years(More)
A multi-disciplinary research program has been established in Australia to identify the causes of sugarcane yield decline (defined as “the loss in productive capacity of sugarcane-growing soils under long-term monoculture”). In one part of that program, five experiments were set up in which the monoculture was broken for 12–42 months by maintaining a bare(More)
The low efficiency of nitrogen (N) use from fertilizer applied to sugarcane is a major concern worldwide threatening the sustainability of sugarcane production. Further, the significance of N losses to the environment is becoming more important as global warming becomes a more significant issue. Improving nitrogen use efficiency is a major challenge for(More)
The reaction of soybean, mungbean, peanut, lablab, cowpea and velvet bean to two species of root-knot nematode (Meloidogyne javanica and M. incognita) was assessed by bare fallowing a field after sugarcane harvest and planting the legumes 4 and 12weeks later. Leichhardt, the most widely grown soybean cultivar in the Queensland sugar industry and three other(More)
This study manipulated the carbon-to-nitrogen ratio (C:N) of seaweed composts by varying the proportion of high N green seaweed (Ulva ohnoi) and high C sugarcane bagasse to assess their quality and suitability for use in agricultural crop production. Seaweed-bagasse mixes that had an initial C:N ratio greater than 18:1 (up to 50:1) could be transformed into(More)
