Free Microbial Water Testing for Produce Growers in Kansas and Missouri

Kansas State University and the University of Missouri continue to offer free microbial water testing to all fruit and vegetable growers in KS and MO, even in light of the COVID-19 situation. We can provide this free testing until our generous grant funding from the USDA National Institute of Food and Agriculture (grant 2019-70020-30358) runs out.
