Agronomy today is very different from what it was 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. Modern agriculture depends heavily on
engineering and technology and on the biological and physical sciences.
Irrigation, drainage, conservation and sanitary engineering, each of which is
important in successful farming, are some of the fields requiring the
specialized knowledge of agricultural engineers. Agricultural chemistry deals
with other vital farming concerns,
