Diversification practices reduce organic to conventional yield gap

Diversification practices reduce organic to conventional yield gap.

Agriculture today places great strains on biodiversity, soils, water and the atmosphere, and these strains will be exacerbated if current trends in population growth, meat and energy consumption, and food waste continue. Thus, farming systems that are both highly productive and minimize environmental harms are critically needed. How organic agriculture may contribute to world food production ha...

Closing the Corn Yield Gap: Management Practices that Improve Soil Quality and Net Productivity but Reduce Global Warming Potential

Meeting the projected global demand for food and fuel from corn systems while conserving natural resources and improving environmental quality can only be achieved by the intensification of existing corn systems. Yield analysis of the central U.S. Corn Belt indicates that there is a large exploitable yield gap for corn. Since 1999, we have been experimenting with optimizing corn management syst...

Supplier diversification under binomial yield

February, 2008 We consider supplier diversification in an EOQ type inventory setting with multiple suppliers under binomial yield and zero leadtimes. We characterize the optimal policy for the model and show that, in this case, it does not pay to diversify and it is better to use a sole supplier. This result constitutes a contrast with the previous ones in the literature assuming various yield ...

Lower Prevalence of Antibiotic-Resistant Enterococci on U.S. Conventional Poultry Farms that Transitioned to Organic Practices

BACKGROUND In U.S. conventional poultry production, antimicrobials are used for therapeutic, prophylactic, and nontherapeutic purposes. Researchers have shown that this can select for antibiotic-resistant commensal and pathogenic bacteria on poultry farms and in poultry-derived products. However, no U.S. studies have investigated on-farm changes in resistance as conventional poultry farms trans...
