Influence of soybean residue management on nitrogen mineralisation and leaching and soil pH in a wet tropical environment
A study was undertaken at the Sugar Yield Decline Joint Venture sub-station at Feluga in north Queensland in 1998 to investigate the effect of soybean residue management on nitrogen mineralisation and leaching, and soil pH.
An assessment of soil and plant silicon levels in north Queensland
Sub-optimal levels of soil silicon (Si) can result in decreased cane and sugar yields. In general, soils of the wet tropics that have undergone significant weathering invariably have inherently low Si levels. To date, ...
Silicon research down under: Past, present and future
Recent research has identified specific Si responses and delineated soils having sub-optimal levels of Si. Future research will focus on developing response functions on a range of soil types identified as Si responsive, ...
Management of legume biomass to maximise benefits to the following sugarcane crop
Previous studies on the wet tropical coast have shown that the management of soyabean biomass can have important implications for residue decomposition and mineralization of nitrogen. The traditional incorporation of ...
Nutrient dynamics and root health in sugarcane soils
Research conducted by the Yield Decline Joint Venture has shown that productivity of the current sugarcane farming system can be increased significantly by soil fumigation or breaking the current monoculture. Associated ...
Management practices to improve soil health and reduce the effect of detrimental soil biota associated with yield decline of sugarcane in Queensland Australia
Yield decline (YD) of sugarcane is a widespread problem throughout the Australian sugar industry. It is defined as “the loss of productive capacity of sugarcane-growing soil under long-term monoculture”. Factors contributing ...
Effect of zero and zonal tillage on cane growth and yield on a heavy cracking clay soil in the Herbert valley
An experiment involving permanent 1.8 m beds, different tillage treatments and dual cane rows planted with a DDO planter fitted with twin opposed press wheels was established on heavy cracking clay soil in the Herbert to ...
Effects of biocides and rotation breaks on soil organisms associated with poor early growth of sugarcane in continuous monoculture
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 ...
Row spacing effect on the growth and yield of several sugarcane varieties in North Queensland
Controlled traffic (matching wheel and row spacing) is becoming an important part of the production system in the Australian sugar industry. However, with harvester and haul-out wheel spacing between 1.8–1.9 m, controlled ...
Impact of management of cane trash and legume residues on N mineralisation and crop N uptake
Inappropriate management of the fallow legume residues has been shown to result in rapid N mineralisation and potentially large N losses due to leaching. This study examined the impact of tillage system and management of ...
