After a recent bushfire consumed all vegetation on his province , a South Australian farmer Brian Fischer decided to etch a gigantic geometric blueprint on the bare dry reason inwards a bid to struggle soil erosion. Without vegetation , the topsoil was vulnerable to erosion past times gusting winds. So Fischer ploughed his province inwards a patchwork of spirals creating long furrows inwards the topsoil. Now no affair which administration the air current blows at that topographic point volition e'er last a furrow to grab the soil. Fischer says the blueprint terms him a few days to brand , merely he expects to relieve fifteen cm of topsoil that would convey otherwise been lost , until the fields are greenish again.
The clever erosion-fighting technique came from his dad , who used it on the farm every bit early on every bit 1944 during 1 of the worst droughts South Commonwealth of Australia experienced. More than 1 one one one thousand thousand hectares of province were destroyed past times a raging bushfire inwards Victoria , prompting closed to farmers to come upwards up alongside this unique solution.
