Sand to the surface is a conduit to water movement.
Sand as a layer below can be a barrier to water movement. Didn’t see that one coming.
Would be interesting to see a running total of amount of water applied. Looked like they just saturated the soil at all times which was good for the demo, but understanding the volume of liquid flowing would help in other ways of understanding.
I’m a clay loam over 100 feet of clay. It is interesting how the comments she makes comes from a dry perspective. So much tile and drainage as the number one way to improve a farm over so much of the upper Midwest, and still everyone talks about trying to conserve moisture.
