Gregg Sanford is an Associate Scientist in the Agronomy Department at UW-Madison. As a cropping systems agronomist, he is interested in diversified agricultural systems and how management philosophy ( e.g. conventional, organic, regenerative) and cropping systems diversity (e.g. simple to complex rotations, pastures, native systems) affect the productivity, profitability, and environmental outcomes (particularly carbon sequestration) of these systems.
Gregg manages a network of long-term research sites throughout the state including the Wisconsin Integrated Cropping Systems Trial (WICST). WICST is a large scale (60 acre), long-term (30 year) cropping systems experiment located at the UW-Madison’s Arlington Agricultural Research Station. With systems spanning conventional, organic, cash-grain, dairy-forage, perennial bioenergy, and livestock grazing enterprises, WICST is arguably the most diverse long-term cropping systems experiment in the world and one of the longest running organic research experiments in the U.S. (after Rodale est. 1981). The large-scale nature of the trial ensures real-world results while the robust experimental design facilitates evaluation of long-term trends while accounting for interannual climate and market variability.
In addition to his research responsibilities he teaches two courses for the University of Wisconsin-Madison’s 134-year-old Farm and Industry Short Course. These courses cover the production and management of grain crops (corn, soybean, wheat) and forage crops (alfalfa, clovers, pasture). He is currently developing a new online summer course for the Agronomy Department called “A Field Guide to Farming”.
