Deep placement of manure into sodic clay subsoils is showing yield benefits six years after treatment.. "We've learnt a lot by digging holes to look at the subsoil and in large parts of the HRZ we've found dense sodic clay subsoils packed so tightly there is little space for air or water movement," Ms Paridaen says... In 2009, with GRDC support, the trials were extended to other locations in Victoria and the best responses were measured after incorporation of 20t/ha of poultry manure...

With heightened interest among growers in using variable-rate application (VRA) to reduce input costs, it is recommended they first conduct on-farm trials to generate paddock data... "While data collected from farmer trials using yield mapping software will never be as accurate as small plot trials conducted by researchers, they are a simple and efficient way of gathering information about variation within paddocks," he said... "One way of being confident about yield differences observed in strip trials is to keep them simple: stick to one or two treatment differences and make the size difference between treatment rates large...
