THIS is how the BERNABÉU PITCH is preserved | Real Madrid

Madridistas we're back with a new episode of the Santiago Bernabéu Stadium's transformation And now we're going to reveal all the secrets that the field maintenance hides Let's start For today's segment I'm joined by Hugo Díaz Hugo how are you How are you doing Very well Fernando How are you Nice to have you here today Hugo is the project leader for ATJ which is the field automation right That's right Then you're the person who's going to tell us a bit about all the secrets that the playing field holds There are quite a few aren't there That's right they are not few Well first of all obviously we are not in a game day It's the first thing that impresses me is that there's no playing field here right There's no playing field Why is that He has completely disappeared Well the playing field is currently in his den We have it in the cellar safely stored Meanwhile we are using the available space we have here A multifunctional slab of about 8 000 square meters And in this case what is being done is to continue with the installation of the 360-degree video marker That's right Very well and also if you look if we walk this way we have these lanes that I understand are where the trays move right Yes specifically here what circulates are cars Cars are the elements used to move and transport the trays from their position in the split mode to their position in the underground How long does the whole process of bringing the trays and storing them usually take Well the total time of the automatic system will be around 6 hours a little less than 6 hours Very well so we've come to the west sideline area which during games is covered with a blue carpet but right now it has been removed and what is now visible is this What is this This is the lid the lid of the hypogeum This is a metal structure weighing approximately 750 tons which is responsible for covering the hypogeum Sure because right now the cap is where the last tray is it would be grass right Correct this is where the sixth tray is located roughly up to where we are now This is where the field ends in match mode Let's go to the hypogeum if you like Perfect let's go to the hypogeum to see it We are currently at level 4 of the underground complex and before going into detail Hugo I need to tell you that you're very used to being down here but for an average person this is crazy This structure this thing you have created is impressive It also seems very interesting that we are here on the playing field and you can still see the lines where the post hole is that would be the penalty spot I understand that precise work is extremely important It's fundamental it's fundamental We have to keep in mind that for example the penalty spot is a good example it's cut in half and once it's raised the two parts have to fit together as is obvious Very well Madridistas here are all the interesting facts Hugo many thanks for being with us today it's been a pleasure Now what we're going to do is continue with José who will tell us some secrets about grass maintenance We're with José María who is the head of pitch and gardening at Real Madrid We made a video with you when the grass was on the surface but things have changed a lot since then haven't they Muchísimo now we are in the underground area and here the growing conditions are completely artificial conditions in which we try to simulate as much as possible the appearance of being outdoors I like it I'll take advantage of the fact that the machine is running right now Tell us what is this machine and what is its function And by the way now that we're here how much light does the grass need and how much watering does it need on a daily basis roughly Right now in this phase we're in we have approximately 16 hours of growth light with the first and last hour simulating sunrise and sunset It is increasing intensity during the first hour and decreasing intensity until it turns off in the last hour During the day for work we have this white light which is a working light to see well and the irrigation we are watering once or twice during the day with the irrigation frames Let's say we put a nozzle on the outlet we have different types of nozzles there is one that provides more water for irrigation yet when we need to apply fertilization treatments We change the nozzle so the spray is much finer distributing it better over the grass blade and allowing it to absorb the nutrients well I have also noticed that the worker currently working with the machine is wearing slippers why is that Well we all who come into contact with the grass have to do this right away here we look for the best conditions for growth But we also need to be very careful about possible diseases that could enter because in these optimal conditions they could also develop easily Then we are very careful with machine disinfections with clothing disinfections and we are using these disposable shoe covers so that there is no external contact with the inside of the grass We went down to level 6 because here you can immediately tell the different light tones for me but they actually have all their functionality right Yes what you can see here is how the grow light works This pinkish light you see is the one we use to provide the necessary light spectra for the plant's photosynthesis With this we ensure the plant grows properly and we also have the feature that for the first time here a system has been implemented that allows us to modulate those wavelengths To function according to the plant's needs provide more of one type of lighting and another so that the plant develops properly according to our needs with the development In the end we need to have the best conditions here in the greenhouse for light temperature and irrigation and we achieve this through all these systems Correct what we have aimed for is to have the best temperature and humidity conditions with the climate control system we also have a CO2 injection system to promote growth and photosynthesis José thank you so much for sharing a bit of the secrets we have here in the hypogeum We hope you enjoyed this video as always if so like it and see you in the next one
