Farming systems which minimise the movement of soil and water will also minimise the loss of nutrients and pesticides... Overall, the only large difference was the lower Zn when superphosphate was applied... In summary, Mike has found a strategy to help him interpret his yield maps - and is now taking the same approach to other paddocks to maximise fertiliser savings...

Research by the University of Western Australia (UWA) and grower groups has found that light grazing of sheep on crop residues over summer has little impact on the following no-till crops... Dr Ken Flower from UWA's School of Plant Biology and Institute of Agriculture led the study to see if summer grazing of residue had an impact on the following crop yields in the no-till system... The results showed that light grazing of sheep on crop residues had no significant effect on the amount of residue, soil properties, soil water, weeds or yield in the following crop...

Types of machinery and how graingrowers use them can make a difference in controlling weeds in a zero-till farming system... A Gason seeder on 25cm tyne spacing achieved 95 percent or 60 percent inter-row soil cover, depending on sowing speed, and uneven soil distribution in the inter-row... A Daybreak disc seeder on 45 percent spacing achieved 50 percent or 30 percent inter-row soil cover and large gaps of up to 25cm in the middle of the inter-row with no soil cover...

Foreword The aim of the research was to find a cover crop, preferably a legume that was fast growing, would leave a heavy stubble residue after knock down, increase the fertility of the soil and reduce soil erosion... The paper outlines cover crops seen in Brazil, USA and France, their purpose, and the idea of planting more than one cover species in a fallow... A farm managed under this system provides the armour to protect the soil from wind and water erosion and acts as a buffer to protect soil life from extreme temperatures' (Brown, 2012)...

There is a renewed interest in the value of livestock as a risk management tool in the wake of escalating crop input costs, climate variability and fluctuating commodity prices... Negative impacts of livestock on soil structure and surface cover must be balanced against consumer demands and constraints of no-till cropping, including weed control issues, lack of soil cover and disease... Integration of livestock in no-till systems - possible pros and cons advantages: non-chemical control of pests including herbicide-resistant weeds; increased biodiversity in plant and soil communities; higher soil organic carbon levels; more available nutrients (nitrogen); and use of excess crop residues and failed crops...

New resource delves into the issue of claying Remediating sandy soils with clay-rich subsoil can generate substantial crop yield improvements, provided that appropriate methods are followed... The Grains Research and Development Corporation (GRDC) has just produced a new publication in which eight growers - including four from SA and one from Victoria - share their stories about their use of clay in improving their soils and productivity... It is critical that growers plan in detail each stage of the process and follow the best practice. "..
