Variable rate gypsum application has allowed the Wilksch Ag business to cut input costs.

GYPSUM and lime are both key inputs in the Wilksch Ag cropping rotation, in particular when growing canola and pulse crops.
High density and time consuming to cart and then to apply, the cost and time taken to spread the soil conditioners can quickly add up, which is why the family enterprise makes sure it has done the research on which areas need either input.
“We do all our gypsum and lime on variable rate,” Randall Wilksch said.
“There are massive variations in soil type over the property, with soil pH (CaCl2) varying from 4 to 9.
“Obviously there is not too much point putting lime out on the soil testing 9 so we have got a detailed pH map of the farm.”
