Paddock demonstration: starter fertiliser locations

To compare the effects of starter fertiliser (ZincStar) on wheat yield at Jil Jil in the southern Mallee district, VIC.

Key messages

The Victorian Mallee has experienced more than a decade of below average rainfall (including 3 droughts). This has placed an enormous amount of financial pressure on the farm businesses. By reducing up-front expenditure on inputs such as fertiliser, provided there is no yield penalty, delayed applications can significantly reduce risk. Delayed applications also allow for rates/inputs to be refined to suit the season.
