There was a post with this title some time ago, but I can't find it with search.
My raised bed along the driveway has a top layer of the fine, grainy "soil" the roly-polies leave behind. I imagine it is their manure. Is this valuable, like worm castings? It is dark and rich looking, mostly when wet.
When I water the water wants to run across the top and it is very hard to get it to soak in. Thus, hydrophobic soil. It seems to be related to the roly-poly-poo. I have literally "billions and billions" of roly-polies under my mulch.
The previous poster was advised to use a soap to make the soil more receptive to water. Would Murphy's oil soap be ok? It's what I have on hand. I don't want to cultivate until after the yams have been harvested.
