The Department of Agronomy seeks to teach the study of the farm-field, its crops, and its science and management. It originally consisted of three sub-departments to do this: Soils, Farm-Crops, and Agricultural Engineering (which became its own department in 1907). Today, the department teaches crop sciences and breeding, soil sciences, meteorology, agroecology, and biotechnology.
History
The Department of Agronomy was formed in 1902. From 1917 to 1935 it was known as the Department of Farm Crops and Soils.

Abstract
Soil compaction can be defined as a reduction in porosity or an increase in bulk density resulting from external or internally applied forces (Alakukku, Laura, 2012). It is regarded with soil erosion, as the costliest and most serious environmental problem caused by conventional agriculture (FAO, 2003). Globally it is estimated that about 4% of agricultural lands or 64 million hectares are affected by compaction, with the majority of this associated with vehicular traffic (Flowers and Lal, 1998). The negative effects of soil compaction have been reported on nearly every continent in the world (Hamza and Anderson, 2005) and these effects have been shown to persist, especially at depth for periods of many years (Alakukku, 1996; Radford et al. 2007; Lowery and Schuler 1994; Logsdon et al. 1992; Hakansson et al. 1988).
