History of agricultural science
1. Agricultural science began with Gregor Mendel's genetic work, but in modern terms might be better dated from the chemical fertilizer outputs of plant physiological understanding in eighteenth century Germany. In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the term «agricultural science». The Hatch Act was driven by farmers' interest in knowing the constituents of early artificial fertilizer. The Smith-Hughes Act of 1917 shifted agricultural education back to its vocational roots, but the scientific foundation had been built.
2. Agronomy and the related disciplines of agricultural science today are very different from what they were before about 1950. Intensification of agriculture since the 1960s in developed and developing countries, often referred to as the Green Revolution, was closely tied to progress made in selecting and improving crops and animals for high productivity, as well as to developing additional inputs such as artificial fertilizers and phytosanitary products.
3. However, environmental damage due to intensive agriculture, industrial development, and population growth has raised many questions among agronomists and has led to the development and emergence of new fields. New technologies, such as biotechnology and computer science, and technological advances have made it possible to develop new research fields, including genetic engineering, improved statistical analysis, and precision farming.
