Preliminary findings from the first three years of UC Davis' 100-year experimental agriculture research project will be reported during a scientific symposium on Thursday, Jan. 23.More than a dozen researchers will make presentations on topics ranging from soil nutrients to cover crops to weeds, from 8:30 a.m. to 11:30 a.m. in the Hanna Room of Asmundson Hall at the university."We'll also be discussing the reasons for superior performance of our organic tomato crop compared to our inorganic tomato crop last year," said Ford Denison, director of the Long Term Research on Agricultural Systems project. "We suspect that it had something to do with last year's unusually rainy weather and the resulting wet soils."The long-term research project was established in 1993 to cover 100 years, examining various farming methods and how they influence the environment as well as the long-term sustainability of agriculture. The research plots are located on a 300-acre agricultural site off Russell Boulevard, about six miles west of the main UC Davis campus.
