Planting vegetables in the sand has been generating good results for farmers in São Paulo Do you know about hydroponics in the sand? This technique has generated good results for São Paulo farmers. It is more economical than the traditional model, made of PVC tubes, which costs 10 times more. The traditional hydroponics system is a technique that does not use soil. The most common is the cultivation of plants inside PVC pipes, through which water mixed with nutrients passes. But some of the dangers of this technique are running out of energy, the pumps not working and, in a few hours, the farmer ends up losing all production. To overcome this bottleneck, researchers from the University of São Paulo brought hydroponics in sand to Brazil in the 1990s, which replaces PVC pipes with beds filled with sand. Initially, the novelty pleased tomato growers and, today, it is used in almost all vegetables. See the full report in the video above. Most watched videos from Globo Rural
