Variable-rate application of some farm inputs offers northern region grain growers cost benefits and improved yields but simple on-farm trials are the key to local success... A new Grains Research and Development Corporation (GRDC) fact sheet outlines how, when and where to vary application rates of inputs such as seed, fertiliser, soil ameliorants such as lime or gypsum, desiccants and growth regulators... When considering variable-rate application, question whether variation exists...

It is important to remember that there are many ways in which PA can be adopted and used to make or save money, improve timeliness or environmental management and to carry out onfarm trials... If a grower purchases a GPS unit using one system and then changes to one using the other system, locations will not be translate accurately... Growers are not confident in using the currently available indices in making cropping decisions...
