Morphology
The meaning is directly compositional: 'mineral' specifies the source/type of the 'fertilizer', so a learner who knows 'mineral' (inorganic substance) and 'fertilizer' (material to improve plant growth) can infer a fertilizer made from inorganic minerals. This modifier+noun compound follows a common, non-idiomatic pattern found across languages, so its sense is immediately predictable to B1 learners.
Etymology
Mineral fertilizer comes from the simple idea of making 'plant food' from crushed rocks. Farmers used ground minerals to make a quick fertilizer that gives plants the nutrients they need, so the name means plant food made from minerals rather than from 'organic' matter.
