Agricultural chemistry deals with the study of chemistry and biochemistry in relation to agricultural production. It also focuses on the processing of raw products into foods and beverages as well as environmental monitoring and remediation. Agricultural chemistry is a multi-disciplinary field that integrates various fields such as microbiology, genetics, entomology, physiology and other sciences related to agriculture. It focuses on the relationships between plants, animals, bacteria and their environment. Agricultural chemistry studies the various life processes by which humans get food and fiber. As an applied science it works on the processes to increase yields and reduce costs. Chemurgy is an important branch of this discipline that deals with the usage of agricultural products as chemical raw materials. Agricultural chemistry aims to expand the understanding of causes and effects of biochemical reactions related to the growth of plants and animals in order to develop the chemical products that will help in establishing the desired control of these reactions. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of agricultural chemistry. It presents researches and studies performed by experts across the globe. This book will provide comprehensive knowledge to the readers.
