Agrochemistry or agronomy chemistry is a branch of science that focuses on studying the chemical processes and interactions involved in agriculture and crop production. Synonyms for agrochemistry include agricultural chemistry, crop chemistry, plant chemistry, soil chemistry, and fertilizer chemistry. These terms all describe the application of chemistry principles and techniques to improve and optimize crop yields, protect crops from pests and diseases, and maintain and improve soil quality. Each of these fields is important to the advancement of modern agriculture and the production of food for the world's growing population. By understanding the chemical makeup of plants, soil, and fertilizers, farmers can make data-driven decisions to optimize their crop production and protect the environment.
