What if a farmer had a stoplight to let them know when they needed to water their fields?🚦🌱 That's kind of what VirtualIrrigationAcademy is trying to do. It's using innovative sensors to help small farmers in 24 countries monitor soil moisture and decide when to water with just a glance. These simple, color-coded sensors improve crop yields, save water, and boost farmers' incomes. Here's how it works: The sensor displays a blue LED light, which signals to the farmer that irrigation isn’t needed at the moment. If, on the other hand, the sensor flashes red, the farmer knows that irrigation is needed. In between these extremes is a green light, which indicates a state of equilibrium but one that could shift quickly. “Everyone can understand colors and patterns,” says Simon Dyer, VIA’s Managing Director. “The tools, the physical products, have taken the stress experienced by a plant in terms of its need for water, and converted it into a color, and in that way a farmer can understand:...
