Popis:	Atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] applied at sublethal concentrations to rangelands, has resulted in herbage production and/or enhanced plant N concentration of desirable warm-season grasses beyond that expected from weed control alone. This investigation was conducted to determine whether this is a metabolically regulated plant response, the result of enhanced soil N availability via microbially mediated processes, or both. Aerobic and anaerobic laboratory incubation studies with an atrazine-amended, rangeland soil indicated no direct effect of atrazine on soil-mediated N transformations [...]
