The Greenhouse

We went to the greenhouse of mister van Leeuwen in Honselersdijk. He grows roses there on 6000 square meters. In the shed is a machine that puts the roses into bundles and puts a plastic wrap over it.

In the greenhouse are assimilation lamps, and the roses grow in substrate mats. The plants need CO2 for assimilation, and the grower puts extra CO2 from the electricity generator in the greenhouse, so the plants grow faster. The total amount of workers is variable, and so does the number of flowers which go to Germany, it depends on the demand. Germany has always been a big demander of flowers, the biggest part of the horticultural products are going to Germany.

The windmill of Nootdorp- Windlust:                                                

   

-The windmill was originally built in Delft in 1787. It came to Nootdorp in 1885.

 

 

-The Windlust is a mill for grain in Dutch it’s called stellingmolen.

 

-Today the windmill lost its importance. The people don’t need it anymore for producing flour. It would be just too expensive. Back in the early days it was the only way to get the valuable product.

 

-Garrets are working by wind. Their movement activates the rest of the mill so the grinding can start. This is all running by the power of the wind.

 

-Length of one garret:4,67 meter

  Height: 23,6 meter

 

-The grain is coming from Holland. From  farmers in the neighbourhood.

 

-The windmill isn’t producing flour anymore.

 

 

 

 

Amsterdam:

 

-in The 17th century was Amsterdam one of the richest cities in Europe. They were the number one in world trade and with their powerful merchant fleet they were unreachable. 

 

 

 

 

 

 

 

 

 

 

Schiphol Airport

 

 

 

 

 

 

●Schiphol is the biggest airport in the Netherlands and also one of the biggest in the hole                                                           world. The motorway goes trough the airport, so some of the planes have to drive trough  a flat bridge to chance the airstrip. It has 3 airstrips, 1 for landing and 2 for taking of.

 

●Schiphol is a very important economy factor for the region. There are working many people from the region, not only at the airport itself, but also in the firms which have a building near the airport. There are many transport (export/inport) enterprises there, but also big enterprises like Yamaha. So if the airport would be closed one time, it would be a real catastroph for the hole region.

 

●Every year, more than 62million passengers use the airport to travel to each place on the whole world. There are working more than 60.000 people at th airport, also in the stores, etc.
