The Doctor of Philosophy in Soil Science at Washington State University is a comprehensive program that gives students the opportunity to specialize in the physical, chemical, biological, mineralogical, geomorphological, and fertility aspects of soils. The program combines theory with practical applications, allowing students to gain hands-on experience through laboratory work and field trips. Students will also have access to state-of-the-art equipment in order to conduct research on topics such as unsaturated water flow, soil-plant relationships, nutrient budgets of cropping systems, movement and transformation of xenobiotic chemicals, and microbial ecology. Upon graduation, students will have the skills and knowledge needed to make meaningful contributions towards improving land use management practices or developing agricultural waste recycling solutions that can benefit both urban and rural communities alike. With a strong network of faculty advisors and alumni support, this program provides graduates with excellent career prospects and the potential to make a lasting impact in the field of soil science.
