Water repelled by soil/dirt
So when I water this section of my backyard, the water beads and runs off instead of soaking into the soil. Even when I till the soil, only a thin top layer gets wet and if I poke it with my finger I can see dry soil underneath. The red arrow points to a dry area where the water has beaded off.
I'm interested in knowing if there is a technical term for this effect so I can figure out how best to fix it. I could just mix in compost and soil and whatnot, but then I won't have learned anything. Thanks for any help
