Nitrates and organic nitrogen compounds from fertilizer and manure enter groundwater through leaching and reach surface water through runoff from agricultural fields. A high level of nitrate makes water unsuitable as drinking water.
NettetThis pollution is mainly caused by inefficient fertilisation. To address this, it is crucial that farmers apply mineral and organic fertilisers in the right dose, taking into account crop needs and nutrient availability in the soil, and at the right time to minimize loss of nutrients to surface and groundwater.
