Assess nutrient composition of irrigation water for efficient farming

Irrigation water in regions with high nitrate levels (above 25 mg/L) can supply up to 50 kg N/ha per season, contributing significantly to crop nutrition. Regular analysis of nutrients like nitrate, phosphorus, potassium, calcium, magnesium, and trace elements enables precise fertiliser adjustments, reducing input costs and minimising environmental risks such as leaching and runoff. This practice enhances nutrient use efficiency, prevents imbalances, and supports sustainable farming, especially in Mediterranean and southern European areas where irrigation for cereals and potatoes is common. Field kits and laboratory testing inform nutrient input tracking, improving planning and reducing over- or under-fertilisation.
