How much fertiliser is wasted by over irrigation?

Over-irrigation can lead to significant fertilizer wastage, as excess water can cause nutrients to leach away from the root zone of plants into the groundwater or runoff. Studies suggest that as much as 30-50% of applied fertilizers can be lost due to over-irrigation, depending on soil type and crop. This not only reduces the efficiency of nutrient use but can also contribute to environmental issues such as water pollution. Effective irrigation management is essential to minimize these losses and promote sustainable farming practices.
