The Department of Soil Science offers the Master of Science and the Doctor of Philosophy degrees with emphasis on soil chemistry, soil genesis and classifica- tion, soil microbiology, soil physics, soil fertility, forest soils and environmental quality. The nonthesis de- .gree Master of Agriculture is also offered. The interests of the students and the facilities avail- able will determine the area of specialization for the research problem. Students will present a thesis or dissertation in their major field; however, Ph.D. can- didates will be expected to qualify in all areas of soil science, Prerequisites: Students who expect to do graduate work in the Department of Soil Science should pres- ent the bachelor's degree from a recognized college of agriculture with a major in soils or the equivalent in other sciences. Their backgrounds should include at least one course in each of the following: general soils, soil fertility, soil genesis and classification, gen- eral bacteriology, general botany, plant physiology, general field crops, general inorganic chemistry, qual- itative analysis, and organic or biochemistry. Those not meeting the above requirements will be required to make up any deficiency early in their graduate work. Students will be held responsible for such basic undergraduate courses' as are deemed necessary for the pursuit of their special program. SOS 5132-Tropical Soils (2) Prereq: SOS 3022.
