Using sophisticated statistical techniques and the U.S. Department of Agriculture’s nutrient database, a team of scientists quantified the degree of nutrient decline in 43 garden crops from 1950 to 1999 (Donald Davis et al., 2005). Their findings are consistent with and reinforce the findings of an earlier study in Great Britain (Anne-Marie Meyer, 1997). All […]

For more than ten years, scientists at U.C. Davis in California have conducted a Long-Term Research on Agricultural Systems project (LTRAS). The impacts of conventional and organic management on tomato production and tomato nutrient concentrations have been a major focus of this effort. On June 23, 2007, the American Chemical Society’s Journal of Food and […]
