Translation guide
The English word "fertile" has two main uses: describing land/soil that is good for growing plants, and describing people, animals, or their reproductive capacity. Japanese uses different words for these meanings, and some expressions are more common in specific contexts like agriculture, medicine, or metaphor.
Describing earth, ground, farmland, or regions where plants grow well.
The most direct and common adjective for fertile soil or land. Used in both spoken and written Japanese.

Means 'rich' or 'abundant' and can describe fertile land, but is broader and often used for rich natural environments or resources.

Describing an environment, period, or conditions that foster something, often negative like crime or conflict.

肥沃 (ひよく) is only for land/soil. Using it for a person's fertility would be unnatural and confusing. Use 繁殖力のある or medical terms instead.
肥沃 is specifically about soil fertility for agriculture. 豊か is broader, implying natural richness, and can be used for forests, seas, etc. For farmland, 肥沃 is more precise.
