A South Australian farmer has devised a clever method to fight soil erosion.
Brian Fishcer created a series of furrows in geometric patterns on his farm north of Adelaide after wildfires burned up nearby vegetation. The pattern of the furrows helps repel winds and prevents wildfires from spreading.
“The fires cooked everything,” Fischer told 3AW radio, “but whichever way the wind blows it’s always at 90 degrees [to the furrows] so it can’t get started.”
Fischer said the project took him several days to complete, but it saved him some roughly 15 cm of top soil.
According to The Guardian, this idea dates back to 1944, when nearly 2.5 million acres of land were destroyed by wildfires in Victoria, Australia.
