  • The effects of season and agriculture on nitrous oxide production in headwater streams

    Received for publication January 3, 2008. Streams and rivers are a globally significant source of nitrous oxide (N2O), a potent greenhouse gas. However, there remains much uncertainty in the magnitude of N2O emissions from these sources, partly due to an incomplete understanding of the factors that control microbial N2O production in lotic sediments. During 2004–2005 we measured sediment N2O ...

  • France: DryExactpro dry feeding system for 1,600 weaners - Case Study

    Big Dutchman pig equipment and feeding systems are used on pig farms in more than 100 countries on all five continents. Naturally, this includes the "End of the Earth", and for good reason: French department no. 29, Finistère, derives its name from the Latin "Finis Terrae" and is the westernmost corner of Brittany, i.e. right where France drops into the Atlantic Ocean. It has much ...
