MANNUM farmer Kevin Bond is one of many Mallee farmers losing prime cropping land to seeps.
"It's incredibly frustrating - the land goes from being the best you've got to not even being able to grow anything," he said.
"Water is a limiting factor in the Mallee, but now we've got too much of it."
Kevin farms with his brothers Geoff and Rodney, and has noticed a number of seeps cropping up in the past decade.
Their property is one of four sites involved in the Natural Resources SA Murray-Darling Basin project, and they have planted lucerne in an attempt to stop large volumes of water flowing downhill into what has become a brown lake at the bottom of the hill.
"Lucerne is a crop that will use moisture in summer - that's where we think this extra moisture is coming from," Kevin said.
"Getting a return from the lucerne isn't important at this stage, but it's good to know we're got the potential to possibly sell lucerne seed or get a hay cut off it if we wanted to go down that path."
