If this translation would be accepted, I'll like to know, why mine was rejected...

Your translations was very rough like word by word. "sabot soulève
poussière du terrain" instead of "le sabot soulève la poussière du sol", which is a lot smoother.

As it's poetry and all is allowed in poetry, maybe your translation could have been accepted but it was somehow very unusual.
