Excursion program Wageningen Soil Meeting

Tuesday, September 20th 2011

Excursion day, with various options. Most of the excursions will leave around 08.30 at the Hof van Wageningen and return around 17.30 hrs; transport, coffee/tea, packed lunch and a refreshment are included.

You can subscribe by e-mail to wageningensoilmeeting@wur.nl or at the reception desk at the start of the conference. All excursions have a limit of the amount of participants. We can advise you to subscribe as early as possible. The excursions will be guided by scientists and most of the excursions have a scientific character; some are combined with a cultural or culinary treat.

All our excursions include shorter or longer walking trips in the open air, so we advise you to bring watertight easy walking or hiking shoes and rain clothes with you. The average temperature in September is 19 degrees Celsius, with a fair possibility of rainfall.

1. Excursion to the National Park Hoge Veluwe

Excursion leader: Roel Dijksma, Wageningen UR, Section Hydrology and Quantative Water Management

National Park Hoge Veluwe is a relict from glaciers that covered the Netherlands during Saalien (2 104 – 1.2 104 years ago). It is a large complex of ice-pushed ridges with an elevation up to 110 m+NAP. Excess rainwater can infiltrate in the sandy soil and feeds the underlying aquifer. This groundwater rises to the surface in springs and brooks in the surrounding area. In this excursion the geology and related water management of the region will be shown. The excursion will start on top of an ice-pushed ridge with an overview to the adjacent river landscape. Then we will visit an old mill-brook, which is fed by Veluwe water, and some of the upper branches of this brook (manmade springs). This field trip is followed by a visit in the afternoon to the National Park Hoge Veluwe and the Kröller Muller Museum which hosts many famous paintings of Dutch masters such as Van Gogh. De Hoge Veluwe National Park is the largest actively managed conservation area in private hands in the Netherlands. The Park covers 5,400 hectares of woodland, heathland, peat bogs and drift sand. It enjoys a wide variety of plants and animals and provides habitats to extremely rare Red List species.

You have the possibility to have a guided nature walk in the park or enjoy a visit to the Kröller-Müller museum on your own.

This trip will leave by bus at the Hof van Wageningen on 08.30 hrs and return around 17.30 hours.

2. Geological and landscape evolution of the Rhine-Meuse delta

Excursion leader: Kees Kasse, VU university Amsterdam, Section Climate Change and Landscape Dynamics

The excursion will demonstrate the geological and  landscape development of the Rhine-Meuse delta in the western and central Netherlands during the Late Pleistocene and Holocene. The impact of climate, sea-level rise and man on delta evolution will be demonstrated in several excursion stops. We will make a west to east transect through the delta starting at the present-day coast where the (sub)recent coastal development and dune formation will be shown. East of the present-day dunes older Holocene coastal barriers systems are present and their relation to Holocene sea-level rise will be explained. The western part of the Netherlands consists of Holocene back-barriers deposits like tidal flat sediments and peats that will be shown by coring. Human reclamation of the peat lands since the late Middle Ages, peat digging and destruction of the landscape followed by lake drainage in historic times will be shown in the field and museum. Further to the east the impact of the river Rhine on the Holocene delta formation is more prominent and a fossil fluvial Rhine course will be visited. Finally, the impact of continental (Scandinavian) glaciation (~150,000 years ago) on the Rhine-Meuse delta and its influence on landscape evolution until the present day will be elucidated in the central Netherlands.

This trip will leave around 08.15 hours at the Hof van Wageningen and return around 17.30 hours.

3. A combined excursion in Wageningen: Wageningen Campus and Mushroom excursion, wine tasting at the Wageningse Berg.

Excursion leader Mushroom excursion: Thom Kuyper, Wageningen UR, Section Soil Biology and Biological Soil Quality

The excursion starts with a tour of the Wageningen campus, including laboratories and a lunch in the Atlas building. In the afternoon you will visit the forest of the Oostereng around Wageningen, guided by a soil and mushroom expert. Oostereng is the name for a number of forest fragments between Wageningen and Bennekom. We will visit the forest fragment close Oranje Nassau Oord. It lays within walking distance of the vineyard. The forest consists of plantations of conifers (Pinus, Pseudotsuga, Larix), and there are also stretches with various deciduous trees (Quercus, Betula) and a lane with old beech trees (Fagus). The soils in the area are generally sandy and have a low pH. At some places remains of the old plaggic soils are present, and there are characterised by higher nutrient levels, especially P. Due to the dominant tree species the major humus profile types are mor and moder. The trees are almost all forming ectomycorrhizal associations. During the excursion we will show the common mushroom species that can be found on such soils in the Netherlands. We will explain which species are mycorrhizal (and show the distribution of mycorrhizas over the soil profile) and which ones are saprotrophs (decomposers) of litter and wood. For litter decomposers we will show extensive bleaching by some (not all) species and the spatial pattern in soil carbon and nutrients that it can generate. During the last five years 160 species of mushrooms have been recorded. However, total species richness of mushroom will probably be a factor 3-5 higher.

The afternoon program will be concluded by a a wine tasting experience accompanied with special Dutch cheeses at the Wageningen winery on the special soils (terroir) of the Wageningse Berg (=“Mountain”; height 42 m (!)).

This trip will leave at the Hof van Wageningen on 09.30 hrs and return at the Hof van Wageningen around 17.30 hours.

4. An excursion about 200,000 years of landscape formation in the surroundings of Wageningen: consequences for current day use.

Excursion leaders: Jetse Stoorvogel and Arnoud Temme, Wageningen UR, Section Land Dynamics.

The Saalien ice age has set the scene for today’s landscape around Wageningen: the cover ice reached the area and deep depressions and pushed moraines were formed. Since then, the landscape was further shaped by a combination of climate change, geomorphological processes, soil formation, vegetation dynamics, and human influence. This excursion tells the fascinating story of this dynamic landscape and discusses the consequences for current day use.

This trip will leave by bus at 8:30 from the ‘Hof van Wageningen’ and returns at ca. 17.30 (We will have relatively little ‘bus time’ but spend most of the time in the field).

5. An excursion to The Netherlands Open Air Museum: Holland in just one day.

The Netherlands Open Air Museum uses authentic buildings, objects and true stories to bring the past to life. Come with us on a journey through the last two hundred years. The museum, with its farmyards, farmhouses, cottages and businesses, farmer’s café and shops, is a hive of activity. The living history will make a lasting impression, bringing back memories and astonishing you by turns. Immerse yourself in the past and get to know the Dutch people and their history.

We will have a guided tour in the museum, with a scientific explanation about the type of buildings in the Netherlands, specifically related to the soil conditions of that area. In the afternoon we will also have the opportunity to visit the HollandRama experience and enjoy the museum by ourselves.

This trip will leave at the Hof van Wageningen on 09.30 hrs and return at the Hof van Wageningen around 16.00 hours.

19.30 Conference diner – Hotel de Wereld, Restaurant O’Mundo

Hotel de Wereld is located in the city centre of Wageningen. It reopened in the spring of 2004 after a complete renovation and resumed its former function of a hotel. In the past 'De Wereld' has known many different designations, the most impressive of which is that it was the backdrop for the signing of the German surrender on May 5, 1945. The modern and stylish interior now contrasts nicely with the building's historic character.
On the ground floor of Hotel de Wereld you will have the opportunity to enjoy the culinary treats on the chef's menu in Restaurant O Mundo. The restaurant is awarded a Michelin star since 2009 for its innovative, honest kitchen and its use of pure ingredients with special attention to vegetables. A light, contemporary style restaurant with clean lines, serving modern personalised cuisine prepared in the kitchen guests can peak into.
