State agricultural colleges are institutions of higher education in the United States that focus on teaching and research in agriculture, natural resources, and related fields. They were established under the Morrill Act of 1862, which aimed to promote education in practical subjects to support the agricultural industry and rural communities. These colleges often provide a range of degree programs, including agronomy, animal science, and environmental science. They also conduct research to improve farming practices and sustainability, and they often collaborate with local farmers and businesses to address regional agricultural challenges.
