Dr. Bullock leads the Data-Intensive Farm Management (DIFM) research team that generates 
and analyzes "Big" agronomic data to improve the way the world fertilizes crops.
DIFM works with participating farmers, using GPS-reliant precision agriculture technology to
conduct large-scale agronomic field trials on farmers' own fields, to generate yield, input
management, and field characteristics data in quantities and of quality only recently imaginable.
DIFM's research also looks at the effects of fertilizer management practices on water quality,
with the aim of discovering efficient means of reducing the loss of nitrogen fertilizer into the 
Mississippi River basin.
