Make intersection between plane and mesh more realistic I have a plane as the ground and a trapezoidal prism as a wooden leg (image below).

How can I make the intersection between the ground and wooden leg more realistic?

The ground is a flat, subdivided plane textured with a normal map and using Cycle's true displacement. The wooden leg is a slightly deformed cube with beveled edges.



When zoomed out, the issue (leg looks like it is floating on top of ground) is more evident:



I am using Blender 2.82 with Cycles engine.
I looked at some reference pictures and i think the area around your plank could use some adjustments to make it more believeable.
For example:


raise the ground a bit where the plank goes into the floor
reduce the amount of moss directly around the plank (the moss in your render kinda looks like it's going into the plank)
