Abstract

Analysis of soil in which corn (Zea mays L.) has been grown annually for 9 yr with or without yearly applications of 3.4 kg/ha atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] indicated that long-term atrazine use had little effect upon soil microbes or biochemical processes. With the exception of a transient inhibition of bacterial growth during the first week after field application, repeated applications did not affect the numbers of viable bacteria or fungi, relative abundance of bacteria producing hydrolytic enzymes, or soil enzyme levels.
