<p>Good advice, Ophiolite! </p>
<p>Keya - I would contact the Geology program and the Crop and Soil program at MSU and let them know your interests and background. If things sound good on both ends, you'll probably have to take a few background undergrad. courses in either Geology or Soils during your Graduate program, depending on your choice. On the soils side, you could definitely do lab/research work after finishing a Graduate program. I don't have enough experience with Geology to give you an opinion on career prospects there. FWIW, my major professor got a B.S. degree in Chemistry and never made less than a A in a Math course. You sound like a good candidate for this line of work - please keep us updated on the process!</p>
