Figure 1: Mean yuield (t/ha) of 20 years (1983 - 2003) cropping comparing tillage systems.. When land has been cropped for many years with multiple cultivations per crop, research is showing that it can take at least three years before the advantages of no or reduced tillage show up in extra yield or more organic soils... Reduced tillage treatments - no-till, reduced-till (one to three passes per fallow of a chisel plough, blade plough and rod weeder) and stubble mulch (two to five passes per fallow of a chisel plough, blade plough and rod weeder) - convincingly out-yielded the conventional aggressive tillage system (involving two to five passes per fallow of a disc plough, scarifier and cultivator) by an average of 24 to 30 per cent per crop over the first 20 years...

In mixed farming systems grazing of the pasture phase can be used to minimise weed burdens but for continuous croppers, or within the cropping phase of mixed farming, some tillage might be needed for integrated weed management... From an overall systems perspective, limited and strategically timed tillage could form part of a productive, sustainable system... A central question emerges : How much damage is done to soil by occasional tillage, strategically applied, in an otherwise no-till system We seek to investigate this question based on the hypothesis: That the agronomic and economic benefits of a strategic tillage operation exceed any agronomic costs due to damage to soil structure...

Legumes make cane more able.. We look at game-changing research that has turned around the fortunes of cane growers through grains diversification.. "If we were going to integrate legumes into the system we had to marry-up with reduced tillage and controlled traffic, so we did a fair amount of work on-farm to determine 'when, where and why'," Mike says...

Future research will determine the best timing for strategic tillage in no-till... In the study, conducted on a deep alluvial clay soil capable of storing a lot of fallow water, 20 years of no-till on average out-yielded full tillage (disc and scarifier) by 30 per_cent... Minimum-tillage (stubble mulching) treatments involving the periodic use of a chisel plough, blade plough and/or rod weeder, and reduced-tillage using the same stubble-mulching implements and appropriate herbicides was also assessed against no-till and full tillage (all crop residues were retained in all comparisons)...
