Agronomy deals with which field?

• A. Crops and soil
• B. Livestock
• C. Ocean ecosystems
• D. Food science

Answer: (A)

The main idea here is the focus on growing crops and managing the soil to support that production. Agronomy centers on field crop production and soil relationships—how soil properties, nutrients, moisture, and management practices like tillage, irrigation, fertilization, pest and weed control, and conservation affect yields and crop quality. It’s about optimizing how crops are grown in real-world farming systems.

That’s why crops and soil is the best fit. Livestock concerns animal production, health, and management; ocean ecosystems fall under marine or environmental sciences; food science deals with processing, safety, and quality of foods rather than growing crops in fields.
