The IDR-Irriga application is a solution developed by the Institute of Rural Development of Paraná IAPAR-EMATER, with the premise of guiding irrigators in decision-making, recommending the ideal irrigation depth for different crops. With an intuitive graphical interface, the app also integrates weather forecasts, providing a complete analysis of water losses in soybean, corn and bean crops throughout their development cycle. Based on soil, water, plant and atmosphere interactions, IDR-Irriga promotes the efficient and sustainable use of water in irrigated crops.
