Though farming has been around since the start of human history, agrobiotechnology has only been around since about the 1920s. It truly came into its own in the 1953s, however, and especially once the structure of DNA was analyzed.
It wouldn't be outrageous to say that agrobiotechnology is the most advanced applied science today. Typical students will not generally have access to genetic engineering laboratories straight away, though, with numerous groundwork subjects like math and chemistry to master first.
Aside from the high-yielding, drought-resistant crops like soy and corn that feed much of the world, agrobiologists also develop, research, and apply numerous novel farming techniques, chemicals, and environmental protection efforts. Their skills also find application in other industrial settings, like the manufacture of biofuel.
Agrobiologists tend to have very broad curiosity and a passion for science. As their working circumstances and their colleagues may change over time, some adaptability is helpful too. They must also be willing to apply painstaking patience over a period of years - many experiments may take that long or fail altogether.
