Employers in northern Iowa are trying to fill a bounty of agricultural jobs. Local economic development officials are touting a series of jobs that are directly and indirectly related to farming. The list includes work in cooperatives, ethanol plants and feed mills, as well as full- and part-time jobs. Low unemployment rates in area counties can make it tough to find employees. The rate in many counties around Mason City ranges between 3 and 5 percent, while the statewide average is 4.5 percent. Jennifer Andrade, an IowaWorks business marketing specialist, says her groups is encouraging more businesses to focus on outreach by visiting local high schools.
