| dc.description | Ten leafy spurge (Euphorbia esula L.) infested sites were selected in two counties of northeastern South Dakota. Soil samples were taken at 15-cm intervals down to 60 cm from infested areas and adjacent noninfested areas
to determine the effects of soil characteristics on ecesis of leafy
spurge. Samples were analyzed for nitrates, organic matter, phosphorus, potassium, zinc, iron, manganese, copper, calcium, magnesium, pH, and
soluble salts. Significant differences were infrequent and attributed to chance. Soil mineral composition, pH, organic matter, and soluble salts did not appear to influence ecesis of leafy spurge. Discriminant analysis was conducted but none of the variables were valuable in classifying the
soils as infested or noninfested. | en_US |
