Water flows are measured and water sample are collected and analyzed for salinity, nutrients and pesticides. Results illustrating the state of the water quality of IRFs are presented. The collected database since 2005 is important for guiding present and future research on non-point pollution induced by intensive irrigation and establishing corrective measures. The results will be disseminated among farmers advancing the fertilization, irrigation, and manure management strategies that are considered more adequate to reduce the environmental effect of irrigation.enIrrigationNitrogenPesticidesPhosphorusWater qualitySuelos y riegosConference MaterialCalidad del aguaRiegoFósforoNitratosPesticidas
