This article considers stresses further down, where the load has already had a chance to spread substantially over a large are.
Loosely speaking, at some depth it's the entire column of soil below that supports the weight of the machine, and piling on more weight will exceed the uncompressed strength from the column, and so it compresses to handle the load. The problem being that compacted soil is bad for plants ability to grow there.
