Meteorological fluctuations define long-term crop yield patterns in conventional and organic production systems

Abstract Variability in meteorological patterns presents significant challenges to crop production consistency and yield stability. Meteorological influences on corn and soybean grain yields were analyzed over an 18-year period at a long-term experiment in Beltsville, Maryland, U.S.A., comparing con...
