Letter Of WeLcOmeDear Workshop Delegates and Friends,

It is our pleasure to extend to you a hundred thousand welcomes, Céad míle fáilte. You are all very welcome to Wexford in the heart of the sunny southeast for the 17th International Nitrogen Workshop.

The Conference Organising Committee has worked hard to provide an outstanding programme of speakers and presentations, which we hope will give rise to a stimulating, informative and sociable Workshop.

We are confident that the Workshop will provide an opportunity for delegates to meet each other, build collaboration through friendship and discuss new developments in policy relevant nitrogen science.

For the first time the Nitrogen Workshop will be using a remote controlled voting system for all delegates to give their opinions/perceptions/recommendations to various Nitrogen related research questions that have been devised to assist in providing policy related research advice. I encourage all workshop participants to embrace the system, ensure that they always have their controllers and to participate fully in the short electronic surveys.

Above all the Organising Committee would like all participants to enjoy their time in Wexford and savour the wonderful food and drink from the region. Should you have queries or require assistance please talk to one of the Workshop Assistants in the white conference shirts or at the registrations desk.

Finally we would like to thank all our sponsors for all their support, without which the Workshop would not have been possible.

We look forward to your contribution.

With kind regards,

Karl Richards Karl Richards

fIeLD trIpS fiEld Trip 1. EU DAIRYMAN PROJECT FARM VISITThis field trip will visit one of the commercial dairy pilot farms participating in the EU Dairyman Project. The farming system and project will be described by the farmer, and an advisor and research scientist working on the project. Dairyman aims to strengthen rural communities in the regions of North West Europe (NWE) where dairy farming is a main economic activity and a vital form of land use. This project also aims lead to a more competitive dairy sector, stronger regional economies and an improved ecological performance with the rural area.

bAnKingMost banks open from Monday to Friday between the hours of 10:00 – 16:00. Each bank has one late opening day per week and all have bureau de change. ATM machines are available and most credit cards are widely accepted particularly Visa and MasterCard, as well as Cirrus and Maestro.

elecTriciTyThe electrical supply throughout Ireland is 230 volts (50 cycles). Plugs are 3-pin flat. Adapters are therefore required for 2-pin appliances. En-suite bathroom shaving points normally have 110 and 240 volt outlets for shaving appliances.

TiPPingIn restaurants and taxis it is customary to add a gratuity of approximately 10% to the bill. In some restaurants Service Charge is already included in the bill as presented to the customer.

sHoPPingThere are a variety of shops in Wexford Town and further information is contained in the tourist literature available on registration. Further Tourist advice is available from the Tourist Centre which is located on the south end of the Quay in Wexford town

WeATHerThere is a reason Ireland is so green! Influenced by the Gulf Stream, Ireland has a mild temperate climate with summer temperatures generally ranging from 14 to 16 ⁰C (60-70 degree Fahrenheit). Rain can be expected at any time (even when sunny) so please have your poncho provided or your own water proof clothing available at all times.
