环境物理学是一门科学学科，致力于确定环境因素如何影响农业和自然生态系统中的生物和物理过程。环境物理学家通过观察生物和物体在其所居住的环境中的行为，并通过诸如以下的环境参数来数学描述行为，试图发现控制土壤-植物-大气系统中质量和能量传输的基本原理。辐射能，温度以及水，营养物以及其他天然和人造化合物的浓度。土壤与作物科学系的环境物理学研究正在解决许多复杂的环境问题，从土壤中的水和污染物迁移到全球气候变化对生态系统结构，功能和生产力的影响。
Environmental Physics is scientific discipline that focuses on determination of how environmental factors affect biological and physical processes in agricultural and natural ecosystems. Environmental physicists seek to discover the underlying principles that govern mass and energy transport in the soil-plant-atmosphere system by observing the behavior of organisms and objects in the environments in which they reside, and mathematically describing the behavior in terms of environmental parameters such as radiant energy, temperature, and concentrations of water, nutrients, and other natural and manmade compounds. Research in environmental physics in the Dept. of Soil and Crop Science is addressing a number of complex environmental issues ranging from water and contaminant transport in soils to the impact of global climate change on ecosystem structure, function and productivity.
