Continued Evaluation of Roadside Development and Erosion Control Experiments. Part I. Causes and Control of Soil Erosion on Oklahoma Highways. Part II. Maintenance of Vegetative Ground Covers on Oklahoma Highways. Part III. Weed Control and Eradication on Oklahoma Highways

摘要

This report records the findings of a one-year extension of a study for which a final report in three parts was completed in 1968. The extension made it possible for the researchers to make additional observations and measurements of experimental plots established for the first study. Recommendations are listed to hasten more effective implementation of the study results. Basically, the data reported is used to reiterate and reemphasize the need to improve vegetation management practices for better erosion control, greater thrift and density of ground covers, and more effective control and eradication of weed species.
