Study Notes
Overview of Biology and Agricultural Science
- Biology is the scientific study of life, with a focus on organisms, cells, genes, evolution, energy processing, and internal regulation.
- Biologists study life at various levels of organization, from molecules to populations, using the scientific method.
- Agriculture science, also known as agriscience, is a multidisciplinary field that applies biology and other sciences to the practice and understanding of agriculture.
- Agricultural scientists, also called agriculturists, are professionals in this field.
- The history of agricultural science dates back to the 18th century, with experiments on the use of gypsum as a fertilizer.
- In 1843, long-term field experiments were initiated at Rothamsted Research in England, some of which are still ongoing.
- In the United States, the Hatch Act of 1887 marked a scientific revolution in agriculture by emphasizing the study of agricultural science.
- The Hatch Act was driven by farmers' interest in understanding the constituents of artificial fertilizers.
- The Smith-Hughes Act of 1917 shifted agricultural education towards vocational training, but scientific research remained an important aspect.
- Agricultural science encompasses exact, natural, economic, and social sciences to address the complex challenges of agriculture.
- The field of biology and agricultural science are interconnected, as biology provides the foundation for understanding the life processes that underpin agriculture.
- Both fields contribute to the development of sustainable agricultural practices and the improvement of food production.
