Morphology
The meaning 'a test under actual conditions' is directly compositional from 'field' (on site/in the real environment) + 'trial' (a test), so a learner who knows both words can infer the phrase. This construction is cross-linguistically common (e.g., Spanish 'ensayo/prueba de campo') and follows a straightforward noun–noun composition, making it immediately comprehensible to B1 learners.
Etymology
The phrase field trial comes from trying something 'in the field' rather than in a lab. The word field means the real-world place and trial means a 'test', so a field trial checks how a product or method works in actual use.
