Abstract:: Twelve high effective Rhizobium trifolii strains were evaluated at four locations in southwest Oregon for the ability to effectively nodulate Mount Barker subterranean clover. All twelve strains possessed antibiotic resistance markers to facilitate identification of strains when extracted from nodules. No significant differences in plant dry weight means could be...

Creator:: Yap, Kathryn H. M.
Abstract:: Although much has been learned about the comparative nodulating behavior of simple mixtures of rhizobial strains under non-soil situations, it is unclear how these findings relate to the factors influencing nodulation success by the complex mixtures of strains found within soil-borne rhizobial populations. Information on the structure and physiological behavior...

Creator:: Hartel, Peter G.
Abstract:: A study was conducted to determine the effects or temperature, solar radiation, rainfall, and saturated flow on fecal coliform numbers in sewage sludge-amended soils. To determine this, four 4.6 X 13.7 m field plots were each amended in summer and in winter with 800 liters of anaerobically-digested sewage sludge, and...

Abstract:: Straw has many uses, as feed, roughage, animal bedding, but these requirements are not sufficient to utilize the available production. In areas where grasskseed is produced, post-harvest straw is burned in the field to help prevent crop disease the following year. This treatment is very wasteful in terms of straw...
