This four-page publication describes work of the STRIPS Research Team, Science-based Trials of Row-crops Integrated with Prairie Strips, in the context of an Iowa landscape and agricultural production. Findings also are presented from the team's experimental watershed sites at the Neal Smith National Wildlife Refuge in Jasper County.
This is an evaluation of seven one-year food system projects funded by the Local Food & Farm Initiative (LFFI). The initiative is funded by an annual appropriation from the Iowa Legislature and administered from the Leopold Center.

This 28-page publication describes field machinery used on six Iowa fruit and vegetable operations. The case studies looked at how size, diversification, marketing strategies and production methods impacted decisions regarding machinery. Here's a summary of the findings in a two-page handout [PDF] about the project that was supported by a 2012 Leopold Center research grant and a one-year 2013 research grant.
This study, conducted every five years, indicates three major trends: increasing age of Iowa farmland owners, an increasing amount of land that is cash rented rather than by crop share agreements, and a shift of land ownership away from people who are not full-time residents.

This fact sheet summarizes research that was part of a five-year project to explore residual nitrate in a variety of cropping systems. The experiment was conducted on a farm in an area where the City of Sioux Center owns several shallow wells that supply more half of the municipal water supplies. The research was supported by this Leopold Center grant.
This report summarizes the statewide impact of the local food industry on Iowa's economy in connection with efforts of the Regional Food Systems Working Group (RFSWG).
