O Pote de Barro que Rega Sozinho por Semanas

The world's most efficient irrigation technique is 4,000 years old. It saves 70 to 90% of water. It costs less than R$25. And it has almost disappeared from textbooks. The clay pot buried next to the roots regulates the flow on its own. No timer. No sensor. No electricity. The physics of unglazed clay does what no modern system can at this cost. Embrapa: 3.5 liters per pot per day. UC Riverside: 50 to 70% more efficient than surface irrigation. Kenya 2013: 97% water savings vs. furrows. 43% more yield per unit of water. It works in the countryside, in garden beds, and on apartment balconies. ━━━━━━━━━━━━━━━━━━ CHAPTERS ━━━━━━━━━━━━━━━━━━ 0:00 The self-watering clay pot 1:20 4,000 years of history 2:24 The physics of clay 7:19 How to install and use 13:35 Who keeps this knowledge? 17:53 R$25 on your balcony ━━━━━━━━━━━━━━━━━━ Irrigation # Home Garden # OllasIrrigation # ClayPot # UrbanGarden # WaterConservation # Embrapa # NortheasternBacklands # GreenBalcony # Sustainability # NaturalIrrigation # AncestralTechnique # AgroSub
