The latest volume in the Long-Term Ecological Research series, presenting two decades of research on the sustainability of temperate, row-crop ecosystems in the Midwestern United States. This compilation of research from the KBS LTER site is significant and could be utilized to inform policy makers and the agricultural industry as well as direct USDA funding. Continuing this research would certainly further advance the understanding of the wide-ranging impacts that arise from agriculture and because agricultural lands comprise over 40% of the Earths land (Owen 2005), the influence could be considerable.
