17.15 - 18.00 Workshop SLAGFERTILISER *) D. Mudersbach (Germany) A. Morillon (France) 18.00 Hrs Departure for Hotel Akersloot from Conference Centre Tata Steel IJmuiden Evening free *) Fertilisers produced from ferrous-slags have been used in agriculture since the end of

19th century. The objective of the RFCS research project SLAGFERTILISER (Jul 2011 to Dec 2014) is to evaluate the effects of currently produced iron and steel slag (BFS, BOFS and LFS) fertilisers and liming materials on crop yields and quality as well as on selected biological and chemical soil parameters in different soil and climate conditions throughout Europe. The partners of the project are: FEhS-Institute, ArGe Httenkalk, Dillinger Htte, voestalpine, ILVA, RUUKKI, Uni Pisa and AGES. Different field trials, long term (f.i. since 1956 in Fuchsenbigl) and short term tests have been carried out in Finland, Germany and Austria. In addition 24 lysimeter tests are carried out in Italy with the soil and water mimicking that from around ILVA steel plant which have been characterised. All new test fields and lysimeters are fertilised with e.g. BOF slag. This will enable comparison of the effects of silicate liming materials under different climatic and soil conditions. The workshop will start with a short introduction to the SLAGFERTILISER project by the coordinator. Two speakers will each give 15 minutes presentations to the current investigations and results. The presentations will be followed by a discussion.

Tourist information

1) Hotel Akersloot 2) Alkmaar 3) Haarlem 4) Amsterdam

Alkmaar Beautiful city, shopping city, cultural city Although Alkmaar is and continues to be a Dutch cheese city, the title covers only part of what it has to offer. For years the city has been entitled to call itself one of the best shopping cities in the Netherlands. As you wander through the streets with their impressive monuments you will be amazed at the beauty of the old town. Shopping, enjoying a drink or visiting a museum? The number of stores has been increased. This makes shopping particularly enjoyable, as many unique stores are now housed in the historic buildings that line the narrow streets. Alkmaar is home to the Dutch Cheese Museum, the Stedelijk Museum Alkmaar, the de Boom Beer Museum and the Beatles Museum. See a totally different side to the city on a canal cruise. Cheese Market Every Friday morning, from early April to early September, there is a cheese market. Unfortunately not in October. The cheese bearers can be seen working in Waagplein (Weighing Square) from 10:00 to 12:30. This colourful, world-famous spectacle is inextricably linked with the city. More information about the Cheese Market: www.cheesemarket.nl.

Haarlem

A hospitable city with a historic heart

Haarlem is one of the most beautiful old cities in the Netherlands. It is a delightful, safe city with ca. 150,000 inhabitants. One of the citys tallest landmarks, the striking tower of Grote of Sint Bavokerk (St Bavos Church), is visible for miles around.

Haarlem lies on the river Spaarne and has a beautiful historic city centre with many attractions including the Frans Hals Museum and Teylers Museum.

There is a wide range of cafs and restaurants in the cosy city centre. And you will find a surprising number of specialist and trendy shops in the side streets of the main shopping streets.

Haarlem is sometimes called the most Flemish city of the North. The monuments created by city master builder Lieven de Key and the large number of places to eat and drink give the city a southern feel.

Amsterdam

Autumn the perfect time to visit

Amsterdam has a moderate maritime climate, resulting in an enjoyable lingering autumn season. By late September, the canals take on a golden hue from the trees reflected in them. The shorter days and the glow of the streetlamps and the illuminated bridges makes you feel like youre walking in a scene from an Old Masters painting.

A cultural harvest

Autumn marks the kick-off of the cultural season each year in Amsterdam. That means new shows, updated productions, exciting exhibitions and a top selection of festivals. Culture vultures should check out Amsterdams impressive theatres and concert halls, and visit at least one of the world-class museums.

Cosy inside

Amsterdam offers plenty of indoor diversions year-round, including the ever-popular canal cruises, shopping for souvenirs or a new wardrobe, or of course exploring the citys nightlife. During the day, kick up your feet at the public library. The newest branch near Central Station has a great section for children and a caf on the top floor with an amazing view of the city. In the evening, get to know Amsterdams cinemas, which play a variety of films from the latest hits to art-house rarities generally in their original language. But perhaps the best thing to do on a chilly autumn day is to search for Dutch gezelligheid (something like a cosy or amiable atmosphere). A great way to start is by heading to a quaint brown caf or intimate restaurant. Grab a corner seat near a window, order a cup of coffee, tea or hot chocolate with whipped cream and watch the world go by as the sun fades behind the Amsterdam facades.
