There are many options for those wishing to study an agriculture-based degree due to the nature of the breadth of the subject. With the exploration of modern concepts such as GM, environmental change, sustainability as well as the business and scientific sides, potential students are spoiled for choice for employment and degree options. In most cases, an undergraduate degree should be enough to find good employment and students in the US taking an undergraduate degree have a distinct advantage over other countries due to the size of the industry here. There remains a shortage of agriculture graduates too, so it should not be difficult to find gainful employment. For those entering into agriculture as a career, once you have chosen this as a major it would be wise to choose such related subjects as chemistry, nutrition, biology and any environmental options your college or university might offer. With an undergraduate degree, you can manage farms and ranches, fisheries and forests, work with soil conservation or many other “outdoors” options.
For research degrees, for example those related to the environment, genetics and selective breeding, agricultural engineering and technology, an advanced degree is a likely requirement – typically an MS if you want to focus on lab work rather than field work.
