If you're interested in pursuing a career in agronomy, you should take college preparatory courses covering subjects such as math, science, English, and public speaking. Science courses, such as earth science, biology, and chemistry, are particularly important. Since much of your future work will involve calculations, you should take four years of high school math. You can learn a lot about farming methods and conditions by taking agriculture classes if your high school offers them. Computer science courses are also a good choice to familiarize yourself with this technology. You should also take English and speech courses, since soil scientists must write reports and make presentations about their findings.
