Students pursuing a degree in sustainable plant systems learn fundamental plant and soil science principles and techniques aimed at developing improved crop plants, and best practices for managing field-, greenhouse-, and agricultural crops, as well as urban landscapes. The School of Plant Sciences (SPLS) and Department of Soil, Water and Environmental Science (SWES) provide instruction for this interdisciplinary undergraduate degree. Their joint efforts prepare students for a broad array of careers in modern agriculture, land management, and agronomic crop production in the Western United States and throughout the world. The academic program in Environmental Horticulture provides practical training and a rigorous foundation in basic sciences to prepare students to enter graduate degree programs and be competitive for industry positions. Students in this program will learn principles and cultural practices for propagating, producing, marketing, and using intensively cultivated herbaceous and woody crop plants for agricultural and ornamental purposes. Environmental Horticulture aims to promote science-based applications that increase plant yield or longevity and enhance environmental quality, while reducing inputs such as labor, fertilizer, water, and chemical pesticides.
