Abstract:: Field studies designed to study residual effects from fertilizer molybdenum were initiated in September 1971 on established grass-clover pastures at ten sites in Western Oregon. Treatments were 0.0 and 1.12 kg molybdenum /ha on plots receiving 0-35-0-20S fertilizer (elemental sulfur-S) and 0.0, 0.56, 1.12 and 2.24 kg molybdenum /ha on...

Abstract:: In a series of greenhouse experiments, isolates representing serotypically distinct subpopulations of Rhizobium leguminosarum bv. trifolii recovered from root nodules of field-grown subclover Trifolium subterraneum cv. "Nangeela"), were evaluated for their symbiotic effectiveness potential, their effect on regrowth potential of subclover, and for their competitive abilities to form nodules. Isolates...

Abstract:: Previous research had identified four serogroups of Rhizobium trifolii indigenous to Abiqua soil (fine, mixed, mesic, Cumulic Ultic Haploxerolls). Nodulation of subterranean clover (Trifolium, subterraneum L.) by two of the serogroups, 6 and 36, was influenced by the application of CaC0₃ to the soil. The studies described in this thesis...
