Occurrence and Stand Density of Tridens flavus (L.) Hitchc. as Related to Some Soil Factors1
- L. E. Foote and
- J. A. Jackobs2
Surface soil samples were collected from within 47 stands of Tridens flavus (L.) Hitchc. “purpletop.” Plant stands were rated as thin, medium, or thick according to the approximate distance between bunches and stand sites were classified as wet, mesic, or dry. The soils were tested for pH, extractable phosphorus (P2 test), readily extractable phosphorus (P1 test), potassium, and texture. There was some indication that occurrence of the species might be associated with phosphorus availability and pH. Occurrence of the species was not associated with any particular soil texture contrary to previous reports. Thick stands of Tridens flavus tend to occur on sites where some soil condition is not particularly favorable for the growth of other plants. These conditions may be of excessively dry or wet soils caused by either topography or a high sand content; or high pH and the resulting relative low availability of phosphorus and other elements.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
