  • Evaluation of an operational method for the estimation of emissions of nitrogen compounds for a group of farms

    The aim of this article is to evaluate a practical method for estimating nitrogen emissions on the scale of a group of farms, to be used in Life Cycle Assessment (LCA). The method rests on the estimation of nitrogen inputs and outputs to calculate the surplus of the annual nitrogen balance on the scale of a farm. The different gaseous nitrogen losses (NH3, NO, N2O, ...

  • Farm digester progress in Pennsylvania

    The Commonwealth of Pennsylvania is home to about 7,000 dairy farms with an average herd size of less than 100 cows. While nutrient and odor management are of great importance to these farms, their overall economic viability appears to be the primary factor driving installation of anaerobic digesters over the past few years. “Pennsylvania has 30 dairy digesters and about 5 swine digesters ...

  • Integrated assessment of runoff from livestock farming operations: Analytical chemistry, in vitro bioassays, and in vivo fish exposures

    Animal waste from livestock farming operations (LFOs) can contain varying levels of natural and synthetic androgens and/or estrogens, which can contaminate surrounding waterways. In the present study, surface stream water was collected from six basins containing LFOs. Aqueous concentrations of 12 hormones were determined via chemical analyses. Relative androgenic and estrogenic activity was ...

  • The Effect of Off-farm Work on the Intensity of Agricultural Production

    Changes in agricultural production methods have been associated with environmental pressure and a loss of natural habitats. This paper explores the extent to which farmer participation in off-farm work (an increasing phenomenon in most developed countries) changes the intensity of agricultural input use focusing, in particular, on fertilizer and crop protection product use. A sample selection ...
