Australian bore water treatment transforms table grapesPosted on August 29, 2014
A salty bore with high sodium and chloride levels was causing major headaches at the historic Swan Valley wine and table grape plantation Twin Hill Wines, established by Steve Kraljevich in the 1930s.
Steve’s grandson Stephen, who now runs the business with his brother Anthony, says leaf burn, poor water penetration and poor performance of fertilisers were wreaking havoc for around three hectares of seedless red and white table grapes they grow for supermarkets throughout Western Australia.
- First there’s the yield. After installing a DELTAwater solutions Grade 5 unit, yield from one area jumped from 600-700 cases to 900 cases.
- The next obvious change was leaf burn. In the first year after installing the treatment system, the vines had less burn and in the second, no burn at all.
- Penetration of water into the soil was the next change. Stephen says leaky mains that used to leave large puddles with white salt rings around the edge disappeared. “After installing the DELTA we no longer had the big puddles and noticed the water was penetrating way better. The white marks the salty water used to leave on the ground disappeared completely in places.”
- Another noticeable change was the amount of water needed to achieve the desired growth and colour, with the added benefit of less fertiliser use. “We used to have to put a lot of fertiliser on to get the vines the right colour, and we’ve noticed we’re using less now to get them growing how we want them to. They are greener and picking up the fertiliser a lot better since installing the DELTA water treatment system.”
