Bacterial communities are highly diverse with each being distinct in composition. Agrobacterium tumefaciens is a common soilborne plant pathogen. Some A. tumefaciens strains can cause crown gall disease, in which infected plants develop a tumor. This bacterium disrupts the host plant by genetically transforming plant cells thereby manipulating the plant’s physiology to benefit the pathogen. Competitive interactions …

Changes In Soil Microbiology Under Conventional And No-Till Production During Crop Rotation, C. J. Hsiao, G. F. Sassenrath, L. Zeglin, G. Hettiarachchi, C. Rice

Kansas Agricultural Experiment Station Research Reports

Soil microbial activity is important for crop production. Soil microbes are involved in nutrient and water cycling within the soil, and interact with crop plants to provide the basic nutrient and water resources needed for crop production. Claypan soils have unique physical characteristics that impact soil biology. This study explored the tempo­ral changes in soil microbiology in a claypan soil under conventional and no-till produc­tion during a crop rotation of corn/winter wheat/soybean/fallow commonly planted in southeast Kansas. We found soil microbial activity changed more in the top two inches of soil than in the lower soil layers. Wheat resulted in …
