Morphology
The meaning 'a type of soil found under grasslands' is directly and transparently derived from combining 'prairie' (treeless grassland) with 'soil' (upper earth layer). This simple noun–noun compositional pattern is cross-linguistically common and follows standard English compounding, so a B1 learner who knows both constituents would reliably infer the MWE's meaning.
Etymology
Prairie soil comes from long grasslands where years of dead grass and roots slowly turned into deep, dark soil. That's why prairie soil means the very 'fertile' ground found under a prairie.
