The College of Agriculture and Life Sciences (CALS) is the second largest undergraduate college at Cornell University and the third largest college of its kind in the United States. Through teaching, research, and extension -- the three components of our land-grant mission -- we strive to improve the nation's food supply and maintain its safety, to enhance the environment, and to help people improve their lives.

  • Brown Rot of Stone and Pome Fruit 

    Strickland, David; Carroll, Juliet; Cox, Kerik (New York State IPM Program, 2019)
    Brown rot occurs on all stone fruit worldwide and afflicts blossoms, twigs, and fruit, both pre- and post-harvest. Several closely-related fungal species, collectively known as Monilinia spp. cause the disease. In stone ...
  • Anthropogenic phosphorus inputs to a river basin and their impacts on riverine phosphorus fluxes along its upstream-downstream continuum 

    Zhang, W.S.; Swaney, D. P.; Hong, B.; Howarth, R. W. (Wiley, 2017-12-23)
    The increasing trend in riverine phosphorus (P) loads resulting from anthropogenic inputs has gained wide attention because of the well-known role of P in eutrophication. So far, however, there is still limited scientific ...
  • Toward a better understanding and quantification of methane emissions from shale gas development 

    Caulton, D.R.; Shepson, P. B.; Santoro, R.L.; Sparks, J.P.; Howarth, R. W.; Ingraffea, A.; Camaliza, M.O.; Sweeney, C.; Karion, A.; Davis, K.J.; Stirm, B.H.; Montzka, S.A.; Miller, B. (National Academy of Sciences, 2014-04-29)
    The identification and quantification of methane emissions from natural gas production has become increasingly important owing to the increase in the natural gas component of the energy sector. An instrumented aircraft ...
  • Sulfur and carbon isotopes as tracers of salt-marsh organic matter flow 

    Peterson, B.J.; Howarth, R. W.; Garritt, R.H. (Wiley, 1986-08-01)
    Stable isotopes of sulfur and carbon were used to trace the dominant flows of organic matter from producers to macroconsumers in Great Sippewissett Salt Marsh on Cape Cod. Spartina alterniflora and sulfur-oxidizing bacteria ...
  • Human health effects of a changing global nitrogen cycle 

    Townsend, A. R.; Howarth, R. W.; Bazzaz, F. A.; Booth, M. S.; Cleveland, C. C.; Collinge, S. K.; Dobson, A. P.; Epstein, P. R.; Holland, E. A.; Keeney, D. R.; Mallin, M. A.; Rogers, C. A.; Wayne, P.; Wolfe, A. H. (Wiley, 2003-06-01)
    Changes to the global nitrogen cycle affect human health well beyond the associated benefits of increased food production. Many intensively fertilized crops become animal feed, helping to create disparities in world food ...
