To estimate amounts of N2 fixed by free-living organisms in soil under annual tillage and minimum-tillage. To determine how soil zone and soil texture affect free-living N2 fixation. To determine how community structure and activity of free-living N2 fixing bacteria is affected by tillage management. To evaluate if/how annual climate affects structure and activity of free-living N2 fixing bacteria. To evaluate how soil moisture affects free-living N2-fixing community structure.
