Abstract

The objectives of this study were (1) to determine the nature of early weed populations on some of the principal cropped soils in Ellis County, Kansas, (2) to determine the presence or absence of any “indicator species” for each sampled soil series and (3) to determine if certain combinations of prisere species occur on any of the sampled soil series. Species composition and occurrence were recorded on the 12 soil series studied. Plant species differed throughout the various soil series, although Eragrostis cilianensis (All.) Link., Kochia scoparia (L.) Schrad., Panicum capillare L., Setaria viridis (L.) Beauv., Solanum rostratum Dunal and Triticum aestivum L. were cosmopolitan species; while Amaranthus retroflexus L., Euphorbia dentata Michx., Helianthus annuus L., Salvia reflexa* Hornem. and Salsola kali L. var. tenuifolia* Tausch were nearly so (See Appendix I). Some of the 12 soil species supported plants that appeared to be indicator species.
