Nitrogen Fertilizer Remains In Soils And Leaks Towards Groundwater For Decades
Nitrogen fertilizer applied to crops lingers in the soil and leaks out as nitrate for decades towards groundwater — “much longer than previously thought,” scientists say in a new study.
Thirty years after synthetic nitrogen (N) fertilizer had been applied to crops in 1982, about 15 per cent of the fertilizer N still remained in soil organic matter, the scientists found.
After three decades, approximately 10 per cent of the fertilizer N had seeped through the soil towards the groundwater and will continue to leak in low amounts for at least another 50 years.
Their paper, “Long-term fate of nitrate fertilizer in agricultural soils,” was published this week in the Proceedings of the National Academy of Sciences of the United States of America.
The findings show that losses of fertilizer N towards the groundwater occur at low rates but over many decades, That means it could take longer than previously thought to reduce nitrate contamination in groundwater, including in aquifers that supply drinking water in North America and elsewhere..
“There’s a lot of fertilizer nitrogen that has accumulated in agricultural soils over the last few decades which will continue to leak as nitrate towards groundwater,”.
Canada and the U.S. regulate the amount of nitrate allowed in drinking water. In the 1980s, surveys by the U.S. Environmental Protection Agency and the U.S. Geological Survey showed that nitrate contamination had probably impacted more public and domestic water supply wells in the U.S. than any other contaminant.”
