That would completely depend on your soil type.
The initial trials were done with soil from Ouyen. Its mainly pretty gutless sand out there......fantastic if it rains and with fert but I would suggest there areas where fertiliser makes no difference.......I would love one of these crews to run some bio stimulant over the sand dune and see if they could improve fertility. I believe in general that over use of mineral fert has eroded the very foundations of our soils....meaning one thing leads to another........more fertiliser......bigger the problem gets. Soil health is the key.

The above link is a good read on how soil should be managed. The amount of farmers...including my dad.....who just keep doing the same thing over and over just like their father are missing an opportunity IMO. Improving your soil is more important that raping for years on end. Aimo DB
