I have a gas line that runs straight through the middle of my property. The soil is incredibly sandy (dune sand essentially), but still grows native species. Not easy to grow anything else. Do you think it would be beneficial for me to mow once or twice a year to provide a top mulch layer to improve water retention, and slowly improve the soil over time? I'm not looking to put food plots in, but I want to plant switchgrass or some sort of screen eventually.
