Aquaphobic Soil

[AlittleSalt]

Years ago, I was lurking at some organic gardening site and started reading about soil that would not soak up water. In 2010, we started gardening. The soil was mostly blow-sand/silt. You could run water on the soil and the water would bounce off and run away - leaving it dry.

I read that can happen especially to soils with a high silt content (Blow-Sand) It happens during droughts when the soil goes a long time with no rain or other precipitation.

Below is a picture of what I am to understand being aquaphobic soil. It is silt that we brought inside on our shoes that settled under a throw-rug. I swept it up and put it where I was going to dump 3 gallons of mop water. You see the results after 3 gallons of water was poured on it.

I'm wondering if Aquaphobic soil is what this is actually called? Anyone know anything about this?
