PhD Soil Science and Agriculture Chemistry is a post graduate course which is meant for those who want to pursue a carrier in agricultural science particularly in the field of soil science. Students get to focus on areas of study such as the soil chemistry, physics, microbiology, fertility, and conservation, and its implication on plant nutrition and sustainable agriculture. The expected time to complete the full-time PhD studies in Soil Science and Agriculture Chemistry is 3-5 years. This is a 1-2 years program, intensive on advanced courses in soil science, which is then followed by 2-3 years dedicated to research and writing of dissertation under the supervision of an assigned faculty member. In the research stage, students conduct field, laboratory, or modeling research on an innovative issue in soil science or agricultural chemistry and are required to write and defend a dissertation when they are through with their studies in order to earn the PhD degree.
The most common entrance exams accepted for admission in a PhD Soil Science and Agriculture Chemistry program are: GRE (Graduate Record Examination General Test), TOEFL or IELTS for foreign universities, GATE (Graduate Aptitude Test in Engineering) for Indian universities. C+ or better in Chemistry, Biology or Agricultural Sciences subjects in undergrad are also crucial essential criteria for the application. Further, there may be requirement of masters degree in any of the related natural sciences fields. Another part of the application is particularly important, such as research experience, publications, internships, statement of purpose, and letters of recommendation. The basic requirement of getting into institutes coupled with sound academic background serves as the key prerequisite for admission.
