Question 1 Report
The following crops will enrich the soil with nitrates except
Of the crops listed, "exoriepus" is the one that does not enrich the soil with nitrates. The other three crops, "calopogonium," "pueraria," and "centrosema," are leguminous plants and have a symbiotic relationship with nitrogen-fixing bacteria that convert atmospheric nitrogen into nitrates, which can be absorbed by the plant and used for growth. The plant then returns some of the nitrates to the soil, enriching it for future crops.
